9) Retinol for Dull Skin
Retinol brightens dull skin. Pregnancy, stress, sun damage, unhealthy lifestyle choices like smoking, binge drinking alcohol, or environmental pollution can all contribute to dull skin. Retinol acts by reducing the production of melanin by skin cells. Skin diseases like melasma, which discolors the skin, are caused by these cells. The skin grows healthier and appears more radiant due to retinol’s ability to stimulate skin cell renewal.
