"Taken to its most basic level, dermarolling introduces tiny punctures to the skin, which makes the skin think it has been damaged," said Dr. Elisa Bennett, a board certified PA-C specializing in dermatology. "This will, in turn, send collagen and elastin in to 'save the day' to heal this 'damage,' which can decrease the appearance of fine lines, acne scarring, hyperpigmentation, and more. In other words: it addresses the concerns of almost every patient that walks through my door."
You can microneedle at home with a tool like the GloPRO Microneedling Regeneration Tool ($199) or have it professionally done. "The 'immediate' effects of dermarolling is, in fact, not a long-term change of the skin. Instead it is edema swelling, which can make the skin look more plump and therefore decrease the appearance of fine lines. The more long-term effects will take up to four to six weeks, as well as multiple treatments."
Microneedling can also make the skin more receptive, so apply your products shortly after for better absorption. Dr. Bennet noted, "It is said that dermarolling can increase the absorption of products by up to 30 percent. The most important products to use after the procedure are hyaluronic acid and vitamins C and E."
