Lactic acid is a natural chemical that helps the body produce energy. When the body produces too much lactic acid, it can lead to skin problems. One of these problems is dark spots, which are due to the accumulation of melanin. Melanin is a pigment that gives skin its color. Dark spots are caused by the overproduction of melanin. Lactoflora Peel Lightening Facial uses a combined approach of lactic acid and tryosinase to break down the melanin and lighten the skin. ToNearMe helps ypu get best of facial!
