Microneedle dermarollers are plastic roller devices with 200 very fine needles protruding from the barrel. Various needle lengths are available for variable depth of penetration through the skin. When rolled over the skin, tiny microchannels are formed, and as these heal up, collagen is produced. Hence the treatment is often termed collagen induction therapy.
The freshly created microchannels also allow easy product penetration. The treatment is thus fantastic for rejuvenation, where a meso-rejuvenation cocktail can be added for additional anti-aging effects.
Dermarollers are often used for reduction of acne scars, being at least as expensive as laser therapy at a fraction of the price. It can also be used to reduce stretch marks and on the scalp to increase the penetration of products used to reduce hair fall.
The treatment is associated with a degree of discomfort especially when longer needles are used. There is a short period of recovery after the treatment, in that mild to moderate redness and sensitivity may be experienced for 2-3 days after the treatment. The treatment can be repeated for better results.
