What's the common denominator with stretch marks, acne scarring, and wrinkles? While all of these skin issues occur for different reasons, they all come about because of a lack of collagen. Collagen is the substance that plumps up the skin and gives it youthful appearance.
Thanks to the aging process, the skin's collagen is lost over time. Other insults damage the skin such as sun damage, acne infections, or folliculitis for example.
When you make small punctures in the skin, it responds by becoming inflamed and will produce collagen as part of the healing process. Micro-needling damages the skin in a minor way and the end result is increased collagen production -- smoother, younger looking skin.
To amplify the microneedling process, serums are used on the skin. These skin care products have active ingredients that work below the surface of the skin for even better results.
