So, how to handle and use dermarollers?
Tip # 1. Handle dermaroller correctly and put a clear protective covers
It is important to know, how you will handle the dermaroller device because you can accidentally break it, if you are not careful. The roller heads are detachable, so you need to be extra careful in removing and putting it back together. Take note that dermarollers are stuffed with microneedles which are prone to breakage.
The microneedles are located on the rollers, so you need to use clear covers to make sure that it not easily damaged. It is important to use clear covers, so you can easily check whether the microneedles are in good condition. The covers will also prevent breakage of the needles in case you accidentally drop it. It will also keep you from pricking your fingers in case you hold it incorrectly.
Tip # 2. Know how to remove the cover correctly.
Every dermaroller device that you bought online or in a drugstore comes with a clear cover. You should know how to remove the cover properly, so you will not get close to the sharp needles. Look for the “Push” word on the clear safety cover which is found on the top and the bottom part of the device. Then, you need to attach the head of the roller to the handle to prevent it from falling. After that, you press the top and bottom part using your thumb and index fingers. Then you slowly pull the cover. In this way, you will not cut your fingers when you remove the cover.
Tip # 3: Learn how to change the roller heads.
Your dermarollers comes with detachable rollers heads with different sizes of microneedles. The microneeedle length that are available for homecare treatment kits are 0.5 mm, 0.75 mm, and 1 mm. Medical dermarollers or those device use in the dermatologist clinic have longer needle length and are used only by trained professionals.
Keep in mind that microneedles in dermarollers are sharp, so you need to be extra careful in removing the clear cover.
Then, you press slowly down on the right and left side of the plastic cover using the thumb and index finger. Then gently pull the roller head with the thumb and index finger. Then slowly put back the other roller head with your microneedle length of choice into the handle.
Tip # 4: Familiarize yourself with the different microneedle size and its uses.
You have to know the different sizes and uses of microneedles so you can effectively use the device as per your skin’s condition. Shorter needle length like 0.25 mm needles are designed for effective delivery of topical agents and serum on the skin. It does not induce bleeding so it will not stimulate collagen production. It is actually painless.
The 0.5 mm to 1 mm needle size is used for moderate and deep scarring, wrinkles and many others. If you are not sure which roller to use better to start with 0.5 mm first, because it is much safer for beginners like you. For safety purposes, you can ask your dermatologist on what is the appropriate needle size to treat a particular skin condition.
Be very careful in using any product to your skin. If you are unsure of what you are doing, better ask for professional advice so you won’t regret at the end.
You have to take note that bleeding is not a parameter to determine if the device is effective or not. It doesn’t mean that you bleed a lot the device is already effective. For 0.25 mm and 0.3 mm, you will not expect any bleeding and pain at all because it is used only for drug delivery while 0.5 and 1 mm needle size may cause mild to moderate bleeding.
Tip # 5. Know how to roll the dermarollers properly
When you are using the dermaroller, make sure that you do not roll it excessively. Too much rolling may cause significant bleeding particularly if you are using 1 mm needle. The pattern on how to roll the dermarollers depends on the area of the skin being treated, the severity of the condition and the depth of the scars.
Again, it is very important to emphasize that if you are not sure of what you are doing, better seeking consult first to a trained professional. It is better to be on the preventive side rather than making irreversible mistake that you will regret later on.
Tip # 6. Know how the effects of the dermarolling therapy on the different parts of the body
You have to know how a certain part of the body reacts with dermarolling therapy, so you won’t be caught in surprise if you see bleeding or not. The face is very vascular part of your body, so you would really expect significant bleeding, while other parts of the body with too many fat deposits may not cause that much bleeding.
The key here is that you don’t have to expect bleeding when you’re doing dermarolling therapy. Don’t roll excessively just to stimulate bleeding because certain body parts have different reaction to dermarolling therapy.
Hope you learn on how to use dermarolling therapy the right way. Follow these tips so you won’t inflict any harm on your skin!
