Skin needling, also known as microneedling, dermarolling and collagen induction therapy, is a procedure used to treat scars and other skin imperfections. It involves puncturing the skin to incite the skin's natural wound-healing process. Dermatologists perform the procedure, which has minimal recovery time and often involves a commitment to multiple office visits combined with at-home care, notes the Journal of Cutaneous and Aesthetic Surgery.
Introduced in the late 1990s, skin needling is offered as a more affordable alternative to laser resurfacing for patients seeking relief from skin imperfections, such as acne scars, stretch marks, wrinkles and even sun damage, according to literature published in the Journal of Cutaneous and Aesthetic Surgery. A roller equipped with approximately 200 needles creates microscopic holes in the skin. This process promotes the formation of natural collagen, elastin and new capillaries as the skin repairs itself.
Skin needling may be combined with topical treatments (such as retinol, peptide or vitamin C creams), notes the International Dermal Institute, as well as other modalities (such as microdermabrasion, subcision or chemical peels) to maximize benefit. Pin-point bleeding during treatment and skin reddening post treatment have been reported, according to the Journal of Cutaneous and Aesthetic Surgery. Measures to protect treated skin from the sun are advised, and antibiotics may be prescribed to prevent skin infection.
