As a natural component of the skin’s acid protection barrier, lactic acid is a fruit acid or AHA. Gentle but thoroughly it removes dead skin from the surface, reduces their thickness and softens them. Fine lines and wrinkles are smoothed out. The soft tingling sensation following application is prove for a stimulation of the blood circulation and that skin is optimally prepared for the nutrients to follow, like e.g. vitamins. Used in hyper-pigmentation, lactic acid aids in brightening of the skin.
