Microneedling stimulates the production of collagen in your skin. The theory is that the procedure's pinpricks cause minor skin irritation, and the skin responds by repairing the pricks by producing new collagen-rich tissue. As a result, the new skin tissue has a more equal tone and texture. It's natural for the skin to lose collagen as it ages or as a result of an accident. More collagen may be produced as a result of encouraging the skin to build new tissue, resulting in tighter skin.
