Microneedling, also known as collagen induction therapy or collagen therapy, is a cosmetic procedure that uses tiny sterilized needles to prick the skin and cause small wounds. These wounds stimulate the body's natural response to produce more collagen and elastin, healing the skin and making it look younger. Nano needling is a similar procedure that uses microscopic hair-like cones to separate cells in the epidermis and allow active products to be pushed into the skin's upper layers, providing benefits such as pigmentation reduction, increased cell turnover, and skin rejuvenation with no downtime. Both microneedling and nano needling are effective and safe skin treatments.
