The cosmetic procedure that uses fine needles to puncture the skin and promote collagen production is microneedling. It is also called collagen induction therapy, skin needling, or dermarolling, depending on the device and context.
A professional device creates many tiny, controlled punctures in the skin. These micro-injuries activate part of the body’s wound-healing response, encouraging remodeling involving collagen and elastin. Microneedling is used in dermatology and cosmetic care for concerns such as acne scars, some wrinkles, and uneven skin texture. Research has also examined its use alongside treatments for hair loss and pigmentation.
Microneedling is not the same as laser resurfacing, which uses light energy, or a chemical peel, which uses a chemical solution to remove or damage selected layers of skin. Dermabrasion mechanically abrades the skin with a rotating instrument and is generally more aggressive. Results and risks depend on needle depth, technique, skin condition, and hygiene; temporary redness, discomfort, swelling, pinpoint bleeding, or irritation can occur.
