Safest finer needles (33G) Compare to the general derma roller with diameter 0.35mm (plated with chemical gold), the new finer roller is made by cone-shape needles with diameter 0.2mm, tip sharp between 0.01mm-0.02mm, all needles plated with 24K genuine gold. With the new needles manufacture technology, the surface of the needle is much more smooth than the general types, combined with 24K gold plated, they will through the skin quickly and easily, which also with help decrease the painful feelings during the process. The finer roller micro needles are atraumatic cone shape needles with new technology 0.2mm diameter stainless steel with HV 370-420, that during the skin puncture process, creates micro and finer wound that seals within minutes after the treatment. What`s more, the highest HV ensure the needles hard enough during the thousands treatments without curved tip and blunt tip; which will not damage and leave the micro metal filing into skin. Because of the finer needles 0.2mm, the blood exudation will be less during the puncture process, more when the finer needles slice through tissues without risk causing traumatic skin, vessel and nerve damage. Comfortable treatment process Based on the 33G-0.2mm needles design, when the needles penetrate into skin during the process, the finer diameter will through the skin quickly with less pressure, however, General needles need much more pressure from the operator to penetrate into the skin. This less pressure will make the patients feel comfortable, and with less pain feeling during the process. Pain patients feel with penetration score 33G VS 30G

Innovative wave design roller drum design The roller drum is with wave design, all the needles though the wave crest without the gap, so during the penetration process, the drum will not contact and press the skin, only leave the needles into skin, which also help reduce the pressure on skin and the pain feeling. The another benefit of the wave design is all the liquid or serum will trough the valley , leave them on skin without push to the sides, this can help skin absorb effectively. Ergonomic design for the handle The handle is designed with special curve, to ensure the operator hold comfortably, the sides and bottom silicone increases the contact friction. More, giving the different sizes of operator palm, the handle designed with three different grip ways.

Micro needle roller sterilization Usually, there are two ways that used for the micro needle roller sterilization, 25KGy Co-60 Gamma Ray and the Ethylene Oxide gas ( EO Gas) according to directive EN2852006+A2:2009, or ISO 10993 What is Co-60 Gamma Ray Sterilization Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. The Benefits and defects of the Co-60 Gamma Ray There are most benefits for the Co-60 sterilization way, such as no need special demands for the product package,the gamma ray will through the package to be inside, even the plastic,tinfoil. More the sterilization process just takes hours to finish,much quicker and easier. But there is some defects for the Gamma sterilization, specially for the medical use device that made with plastic materials, during the sterilization process, the gamma ray will generate high temperature, which will cause the plastic to change colors, the light color the plastic materials, the obvious changes, such us with transparent PC and ABS materials, clearly changes to be semitransparent yellow, however, the deep color plastic after gamma ray sterilization without obvious changes, such as dark black. So, if need the Co-60 sterilization, must consider the plastic color changes caused the high temperature process. What Are Ethylene Oxide And Sterilization By Ethylene Oxide Ethylene oxide (EO) is a gas commonly used to sterilize medical devices and products chemically. Ethylene oxide is a potent and highly penetrating alkylating agent. These characteristics make it an extremely effective sterilizing agent. However, at certain levels, ethylene oxide is also capable of causing cancer. Sterilization by ethylene oxide kills microorganisms through exposure to ethylene oxide gas under vacuum and humidity. EO is used either as 100% EO or in combination with carbon dioxide. What Items Can Be Sterilized By Ethylene Oxide Standard devices and materials sterilized with ethylene oxide are plastic materials (such as plastic devices), gowning materials, heat-labile equipment, and powders. Materials that can be moist heat sterilized can also be sterilized via ethylene oxide. However, if all materials in your device or product are easily sterilized via moist heat, moist heat is the cheaper and easier sterilization option. How Is Sterilization By Ethylene Oxide Performed? The exposure time for most EO sterilizations is relatively long (around 6 hours). The gas aeration period is also lengthy, up to 24 hours or more. After loading items into an ethylene oxide sterilization chamber, a vacuum is applied. Next, the chamber is filled to the desired relative humidity. Then an appropriate concentration of EO gas is added. Items undergoing sterilization rest in the EO gas under vacuum and humidity for the desired exposure time. Finally, the gas is slowly and safely evacuated from the EO sterilization chamber, and the sterilized items are given ample aeration time to support EO off-gassing. For sterilization validations, the D value of biological indicators used for EO sterilization validations may range up to 10-fold over the range of relative humidity values. The Benefits and defects of the EO Gas sterilization For the derma roller system line, which made most by kinds of different plastics, the benefits are obvious, that will not cause color change, so no need consider the materials choose during the produce, and meets the different color demands from customers. According to the EO gas sterilization process, it obviously show that the process will take much longer time than Co-60 gamma ray, and need consider the gas residue, which is harmful and dangerous for human body. So, often after the sterilization process, it often needs 7 days gas release to ensure the residue is safety to human health. More, in the micro needle roller system line, the EO gas sterilization way needs special package way for the product. Often, we use two kinds of package ways. First, a cheaper package way,plastic-paper bag, which will also save much labour cost, just need machine to seal the bag. But this package design has few defects. 1. The plastic and paper bag is easy to broken 2. During the sterilization process the risks that wet bag or bulge bag phenomenon will happen 3. The valuation date is shorter considering the goods will not be transferred or stored under standard environment , often the valuation is one year. Second, the plastic-Tyvek paper package design. This way materials cost is much higher and need more labour cost. But it is no easy to happen broken phenomenon and even under the no standard environment, the valuation will be as long as three years.

There are various sizes of derma roller needles ranging between 0.2mm and 3.0mm, each suited for particular sets of skin complications. Needles 1mm long and below are suitable for the treatment of simple operations while longer ones are recommended for more prominent skin ailments. In this article, the focus will be mainly on different needle sizes, who, when, and how to use each one of them for the best results. 0.2 – 0.3mm size skin roller needle The 0.2 to 0.3mm size skin roller needles are the smallest of derma roller microneedles which are used basically for what is referred to as transdermal absorption, or simply, enhanced absorption of skin care products. It does not stimulate the growth of collagen, but it does thicken the epidermis making it easier for the skin to respond positively to various skincare products. Regardless of the derma roller size, the skin is likely to exhibit redness and irritation from regular use. However, the 0.2/0.3mm needle can be used every other day with no side effects. As long as the rolling is not done forcibly, there should be no bleeding, save for minor blood spots which should be normal. It is the most suitable needle size for the areas around the eyes and the neck, therefore; avoid using longer needles on these regions. 0.5mm size derma roller needle The 0.5mm derma roller needles are the perfect size of needle for anyone looking to treat shallow wrinkles, UV damage, light scarring, and hyperpigmentation. It also helps in the boosting of product absorption for quicker and more efficient results. Derma rolling naturally causes loss of skin moisture and dryness, so longer needles must be used carefully. The 0.5mm needle can be utilized weekly or twice a month without any reverse contraindications. Users experience minimal pain and blood spotting which heals within a short time, therefore; numbing cream should not be necessary. Effects will vary from user to another, and while some might exhibit excessive reddening and skin irritation from weekly use, others will not. Your skin reaction to derma rolling should help you determine the frequency at which you can use the 0.5mm size needle. Beginners should practice caution with the choice of needles, hence; should not use the 0.5mm needle on a weekly basis. 1.0mm size derma roller needles These derma roller size needles are more effective in inducing the production of collagen as compared to smaller needles. Besides helping in the reduction of hyperpigmentation and UV damage, the 1.0mm dermaroller needles can treat stretch marks, scars, and even wrinkles efficiently. Users of these needles are also known to enjoy a smoother skin texture, as well as an even complexion. These size needles can be used comfortably on the cheeks, forehead, and the lower neck, but care should be taken along sensitive areas around the eyes and behind the ears. Owing to deeper needle penetration, users will experience moderate pain which will require a recovery period of up to a week, depending on the aggressiveness of the operation. A numbing cream is necessary, especially to those people who are less tolerant of pain or have more sensitive skins. Beginners are advised to go through derma roller treatment once in every 4 to 6 weeks, and not more than twice in a month as that stagnates collagen production. Procedures can only be repeated once the patient has recovered fully from the previous procedure. 1.5 – 2.0mm size dermaroller needles These are medium size derma roller needles that can be used for the treatment of several skin ailments, mostly those found in other parts of the body other than the face. They are ideal for the back of the hands, abdomen, thighs, arms, and the decollete areas, for treatment of mild to not-so-severe scars, wrinkles, and stretch marks, but must not be used by beginners without prior derma rolling knowledge or professional supervision. As expected, needle penetration goes deeper with size; hence, the 1.5mm derma roller and the 2.0mm derma roller size needles are bound to cause relative pain during treatment. An anaesthetic must be used before the operation to ease the pain on the patient, but the aftermath should last for less than 7 days. Repeat procedures can only be done after full recovery of patients, in most cases between 6 weeks to 2 months. 3.0mm size derma rollers microneedles These are long needles that should not be used as easy-fix solutions. There are risks involved and are only recommended for use in the presence of a professional. The 3.0mm long needles are not ideal for facial procedures as the skin on the face is said to be much lighter compared to that of other parts of the body. Depending on the frequency and the intensity of the procedure, 3.0mm derma roller size needles should be used on hardened regions such as thighs, feet, arms, lower and upper back, butts, and the back of the hands. For people with severe burn scars and stretch marks, these are the perfect needle sizes because of their ability to penetrate much deeper into the skin. Users will experience various drawbacks that should be normal after treatment. As a precaution, however, application of anaesthetic is mandatory. Light bleeding, swelling, reddening, and dryness characterize any operation where needles 3.0mm long are used. The recovery period should normally be between 7 and ten days, during which time all other skin procedures must be stopped. Another derma roller treatment cannot be repeated until after two months when the patient has fully recovered.

Precautions before Derma Roller Treatment In as much as micro-needling, or simply derma rolling can be effective, you are supposed to be extra cautious. There are common mistakes that people commit in their quest for correcting their various conditions besides using the wrong sizes of needles. If you have active acne, a skin disease, or a sore skin, do not undergo any derma roller treatment. Consult your doctor in case you are under any medication before going through a procedure. To avoid skin disease transmission, always use your personal kit and avoid sharing. Do not roll forcibly; this causes irregular swelling and unnecessary irritation that takes longer than normal to heal. Do not apply make-up or tanning lotion immediately after treatment as derma rolling creates micro-passages into the deeper skin layer. Derma roller results Using the right derma roller size at the right time translates to effectiveness. What people must realize is that micro needling is a long-term process whose results might take some time to manifest. It is normal for the skin around the operating region to plumb as a result of growth and blood pumping into those areas. This normally takes less than 24 hours, although side effects like reddening and dryness might be prolonged depending on the magnitude of the procedure. Reduction and the gradual disappearance of stretch marks, scars, and wrinkles happen when new elastins and collagens accumulate under the skin, which should be after 3 to 6 procedures. It is imperative to understand that using the wrong size of needles for skin treatment only aggravates the condition, and it might take you even longer to correct.

A derma roller is a small roller that has a number of small needles on it that you use to make holes in your skin, a process called microneedling. The idea is that these tiny holes can help your skin produce more collagen, a protein that helps with healthy-looking skin. It can also open up your skin to serums and hydration products. Typically, you use this treatment on your face, though you can use it on other areas of your body, particularly areas that have scarring. Using a derma roller is fairly simple, though you should clean both your skin and the derma roller before and after use. 1 Disinfect the roller before use. Tiny needles are penetrating your skin, so obviously you want to disinfect those needles first. Soak the roller in 70% isopropyl alcohol. Leave it for 10 minutes. 70% is better than 99% because it doesn't evaporate as quickly. After it's soaked for 10 minutes, pull it out, and shake off the excess alcohol. Let it air dry for a few minutes. 2 Wash your skin in warm water. It's important to start with clean skin. For example, you could use a gentle foaming cleanser for your face to thoroughly clean your skin. Bar soap or shower gel and water for other parts of your body are fine. The point is you need to start with clean skin, and it's fine to use your typical cleansers. However, you don't want to start with anything too harsh, so skip facial cleansers with things like salicyclic acid in them. Opt for something gentler. 3 Disinfect your skin if you're using longer needles. Longer needles mean deeper penetration, which in turn can lead to infection. If you're using needles longer than 0.5 millimeters long, you should disinfect your skin in addition to the roller. Gently swipe rubbing alcohol (70% isopropyl) all across your skin. 1. Begin with a numbing cream if you prefer. Most people aren't sensitive to the needles, but if you're sensitive to pain, you can use a numbing cream first, particularly if you have needles that are 1.0 millimeter or longer. Rub a lidocaine cream into the area, and leave it for 20 minutes before you start rolling. · Wipe off any excess cream before you roll. 2 Roll vertically. Start on one edge of the area. Roll up it from top to bottom, avoiding the eye socket area if you're doing your face. Lift it up, and roll over the same area again, repeating 6 times in total. Move the roller over and repeat. Keep going until you've done the whole area. If you're using longer needles, such as 1.0 millimeter or higher, you may see some light bleeding. However, if you notice more than pinpricks of blood, you should stop. You may need a smaller needle. 3 Roll horizontally. Starting at the top or bottom, roll across the area horizontally. Lift up, and roll over the same area again. Roll over it 6 times altogether. Move down or up a little bit, and repeat the process until you've done the whole area. You can also go diagonally, but that can lead to uneven needling. 4 Stop rolling after 2 minutes, particularly on your face. You can overdo it with microneedling, especially on your face. Therefore, it's a good idea to limit each rolling session to under 2 minutes if you can. 5 Use a derma roller every other day or so. Using it too often can lead to inflammation. At most, try using your derma roller 3 to 5 times a week, making sure to give your skin a break every now and then. Some people only use this treatment every 6 weeks, for instance. 1 Rinse your face. After you're done, rinse off your face. You can just use water, since you've already cleansed your face, but you need to remove any blood traces. You can also use a gentle cleanser if you prefer.[7] 2 Hydrate your skin. It can help to use a hydration product after you're done. For instance, a sheet mask can help you hydrate and heal. Another option is applying an anti-aging or anti-wrinkle serum after you're done. These serums will penetrate more deeply because of the micro holes. 3 Clean the roller in dish soap and water. Wash your roller off using dish soap and hot water. Dish soap is better than other soaps at removing the tiny particles of blood and skin on your roller. Put the soap and water in a clean container, and shake the roller around in the water. 4 Disinfect the roller after use. Shake off excess water. Put the roller in 70% isopropyl alcohol. Let it soak for 10 minutes before shaking off the alcohol. Give it a chance to air dry before putting it away. Don't share your derma roller with anyone else. Because it penetrates the skin, you could share blood-borne diseases

A derma roller is a small cosmetic roller used to keep your skin healthy and treat acne and scarring. To avoid contaminating your skin, clean your derma roller before and after you use it. Use rubbing alcohol or hydrogen peroxide to sterilize your derma roller, sanitize your derma roller with purifying tablets, or use soap for a quick clean. With some disinfectant and patience, you can easily clean your derma roller. Method1 Sterilizing Your Derma Roller 1 Rinse your derma roller under warm water for 2-3 seconds. Turn on your faucet, and hold your roller under the water for a few seconds to get rid of any superficial debris, like dead skin or blood.[1 ]This helps remove skin particles that may not come off with just alcohol. 2 Pour isopropyl alcohol or hydrogen peroxide in a small dish. Fill up the bowl with 60-90% rubbing alcohol or hydrogen peroxide so the roller is completely covered. If you use less than 60% isopropyl alcohol, it will not sanitize your derma roller.[2]You can use a plastic Tupperware container or ceramic dish, for example 3Soak your derma roller for 60 minutes to thoroughly sanitize it. Place your derma roller upside down in your container. The needles of your roller should face upwards. 4 Rinse your derma roller with warm running water for 30-60 seconds. After your derma roller soaks for an hour, remove it from your container and hold it under running water. This gets rid of any remaining skin particles and leftover alcohol or peroxide.[3 5 Lay your roller upside down on a paper towel and let it air dry. After you sanitize your roller, it is important to keep it free of germs. Flip the handle around so the roller is upside down, and put it on a clean paper towel. Let the roller sit for 10-20 minutes.[4] Air-drying is the best method to dry your derma roller. Towels can get caught in the needles. 6 Put your derma roller back in its protective container after it is dry. Once your roller is dry, place it inside its container and fasten the lid. This way, your derma roller stays clean and disinfected.[5]If you store your derma roller elsewhere, you can spread bacteria to your face when you next use it. Method2 Using Purification Tablets to Sanitize the Roller 1 Use either specialty tablets or denture tablets to clean your roller. Many derma roller companies sell purifying tablets to make cleaning easy. If your roller came with a tablet, read the instructions detailed on the packaging. If your derma roller does not have a cleaning tablet, use denture tablets instead .Denture tablets are designed to sanitize, and you can safely use them on your derma roller 2 Fill a container with warm water as outlined in the instructions. Different purifying tablets will call for varying levels of water. Typically, they use about 1 c (240 mL) or so. Measure the water with a measuring cup, and pour it into a small dish.[6] If your derma roller cleaning container has a fill line on the outside, simply use that as a guideline as you fill it. 3 Put 1 tablet inside your container and submerge your derma roller. Rip open the packaging around the individual tablet, and place the tablet into the water. Once you dunk the purifying tablet in the water, the chemicals in the tablet mix with the water to create your sanitizing solution. This happens instantly, so place your derma roller into the water right after the tablet.[7] Make sure the entire derma roller is completely covered for a thorough clean. 4 Leave your derma roller in the solution as outlined in the directions. Follow the directions on the packaging to ensure your derma roller is completely sanitized. Some purifying tablets only need to soak for 5-10 minutes.[8] If you are using denture cleaning tablets, leave your derma roller in the solution overnight. 5 Rinse your roller lightly in warm water before placing it on a paper towel. Once your derma roller has soaked thoroughly, use warm water to rinse off the solution. Then, set the roller on a clean paper towel for 10-20 minutes so it can air dry.[9] If you pat your roller to dry, it may bend the needles. If the needles are bent, they may scratch your face. Method3 Utilizing Other Cleaning Techniques 1 Soak your roller in soapy water for 20 minutes for a superficial clean. Fill up a plastic container halfway with warm water from your faucet. Add 3-5 drops of dishwashing liquid or Castile soap, and mix it up with a spoon. Then, place your derma roller in the container upside down. Soak your derma roller for 10-20 minutes. This gets rid of any surface blood or skin cells. 2 Use a clean, soft toothbrush if you want to scrub away dirt or residue. Derma rollers have many small needles that poke into the pores of your skin. Dirt, blood, and dead skin can get trapped in between the needles. For a deep clean, use a new, clean toothbrush with soft bristles. Turn on warm water, and hold your roller underneath the stream. Brush your roller gently with your toothbrush for about 60 seconds. This gets rid of dirt and residue that alcohol or soap may not lift off. While this is optional, it provides a deep, thorough clean. If you use a used toothbrush, you can spread bacteria to your roller. Roll your roller over a wet sponge to get rid of any remaining debris. Place the wet sponge on a clean, flat surface. Then, move your roller back and forth across the top of the sponge. Do this for 20-45 seconds to get rid of dirt and residue that other methods may not remove. This is optional, though it is a good idea if you frequently use your roller or have an older roller. Use a new, clean sponge to avoid contaminating your face. 4 Rinse your roller in warm water and let it air dry. Use warm water from your faucet to wash your roller off and get rid of any dirt, skin, blood, or debris that came loose when cleaning it. Then, place your roller upside down on top of a clean paper towel. Your roller should dry in about 10-20 minutes. Tips Regularly cleaning your derma roller may make it last longer. A roller typically is good for 15 uses. Sterilization removed all microorganisms, while sanitizing thoroughly cleans but an allowable amount of microorganisms remain Warnings Avoid using harsh chemicals like bleach on your derma roller. These chemicals can damage your skin when you use the roller. Do not use boiling water when cleaning your derma roller. This can damage the needles. If you don`t clean the derma roller, it can grow bacteria, which transfers to your skin the next time you use it.
