What Is A Dermaroller? It is a skincare/cosmetic device used to help rejuvenate the skin, stimulate hair growth, treat acne scarring, and reduce signs of aging. It can fill in fine lines and wrinkles, reduce under-eye bags and dark circles, improve skin texture, reduce the size of pores, and fade blemishes and marks. The dermaroller was introduced in the mid-90s, however, it got traction within the last few years as it is an accessible, effective, and relatively non-invasive skin treatment. Over a short period of time, it has gained mass popularity and acceptance as it is a simple, cheap, safe, and effective technique requiring minimal training.
It also can be used for intradermal delivery of drugs and vaccines. Studies suggest that 90% of the serum gets absorbed into the skin during dermarolling. The dermaroller dilates the infundibulum and hence that serves as an additional route of penetration of the drugs and cosmeceuticals.
Types Of Dermarollers
Five basic types of medical dermarollers registered with the FDA are as follows and most dermarolling devices are adopted from these elementary types
- C-8 (Cosmetic type), is the basic dermaroller with a needle length of only 0.13 mm (130 ?m) used for enhancing penetration of topical agents. It is completely painless.
- C-8HE (Cosmetic type for hair-bearing surfaces, scalp) has a needle length of 0.2 mm (200 ?m). Even this length is below the pain threshold.
- CIT-8 (CIT: Collagen Induction Therapy) has a needle length of 0.5 mm (500 ?m) and helps in collagen induction and skin remodelling.
- MF-8 type has a needle length of 1.5 mm (1500 ?m). This creates deeper microchannels on the whole epidermis and dermis and at the same time destroys scar collagen bundles.
- MS-4 is the only dermaroller that has a smaller cylinder, 1 cm length, 2 cm diameter, and subsequently 4 circular arrays of needles (total 96 needles) that have 1.5 mm length. It is used in areas where better precision and deeper penetration is required. It is mostly used on facial acne scars.
- Devices similar to MS-4 are available with needle lengths of 0.5–0.75 mm, which are used for thin-skinned areas such as the periorbital and perioral regions.
Home Care Dermaroller
Home-care dermarollers (C-8) are used by patients themselves as they are of needle length less than 0.15 mm . They can be used twice or thrice a week for up to 100 times. After use, the rollers should be cleaned in hot tap water and shaken dry
Precautions To Be Taken
- Individuals with pre-existing eczema, psoriasis, and warts should not use rolling as it is likely to exacerbate the condition.
- Avoid derma rollers in active acne (open wounds or cysts).
- A person needs to have a fairly high threshold for pain and discomfort caused during the procedure.
- One needs to take care of device hygiene by cleaning it with a sterilizing agent and soaking in alcohol-based soak.
- Cleanliness of skin is utterly important as the procedure is associated with blood.
- Ensuring fineness of the needles, as thick and blunt needles would damage the skin.
- Need to take precautions in people with health conditions like diabetes which can slow down wound healing.
- Taking anticoagulants or other medications, if required.
