A professional-grade serum for men with botanical extracts will reduce inflammation, regulate the level of oil in the skin and brighten the complexion. A serum with alpha hydroxy acids, or AHAs, for men will stimulate skin cellular turnover, while promoting the health of the new skin cells that replace the dead skin cells. AHAs also help with the fading of pigmentation and dark spots. Retinoids in a serum for men will act as a messenger to cells deep within the skin, prompting increased production of collagen and elastin that reduce the depth and appearance of fine lines and wrinkles.
