Skin needling, often called micro-needling therapy, is a minimally invasive skin-rejuvenation procedure that involves the use of a needling machine containing multiple fine needles. The needles puncture the skin to create a controlled skin injury. Each puncture creates a channel through the outer layer. This triggers the body to fill these microscopic wounds by producing new collagen and elastin in the papillary dermis resulting in improvement in skin texture and firmness, as well as reduction in scars, acne scars, wrinkles, fine lines and shrinking pore size, and stretch marks.

Because the epidermis remains intact, the procedure can be repeated safely and is also suited to regions where laser treatments and deep peels are not typically performed. It is sometimes the preferred treatment over laser as there is no risk of burning. The procedure is well tolerated by patients with minimal downtime. The number of needling sessions depends on the individual skin condition.
