Microneedling increases the production of collagen and other healing factors by causing trauma to the skin. Collagen is an essential protein that helps keep the skin looking youthful, with a firm, smooth, and stretchy texture. Aging causes the decline of collagen in the skin, contributing to wrinkles and other signs of aging. Skin can also lose collagen due to injuries, such as acne scarring, stretch marks, or other scars. It is important to realize that microneedling is not a quick fix, as it involves the growth of new skin. It can take several months for a person to see the full results of the procedure.
Microneedling works by encouraging your skin to make more collagen. The idea is that pinpricks from the procedure cause slight injury to the skin and that the skin responds by making new collagen-rich tissue.
This new skin tissue is, in turn, more even in tone and texture. It’s normal for the skin to lose collagen via age or injury. By encouraging the skin to make new tissue, there may be more collagen to help make the skin firmer, too.
