Professional-grade serums are typically more lightweight products with higher concentrations of active ingredients. Serums are traditionally always applied first, as they penetrate quickly and are more for treating a specific condition. Professional-grade serums are formulated to improve texture, lighten dark spots, diminish fine lines and wrinkles or boost hydration.
A professional-grade serum with botanical extracts will help to reduce inflammation, regulate the level of oil in the skin and brighten your skin's complexion. An alpha hydroxy acid (AHAs) serum will stimulate your skin's cellular turnover, while promoting the health of the new skin cells that replace the dead skin cells. AHAs also help with fading pigmentation and dark spots. Retinoids in a serum will act as a messenger to cells deep within the skin, prompting increased production of collagen and elastin, reducing the depth and appearance of fine lines and wrinkles.
