As dehydrated skin can contribute to acne and congestion, lactic acid comes in as a hero to treat acne as it helps to moisturize the skin. It helps to reduce the appearance of acne by speeding up the rate of cell turnover and helps to produce new skin cells and provide you with healthy skin. 

2# Kills Bacteria- Accumulation of bacteria is not just the cause behind that stubborn acne but can also cause various skin problems and infections. Lactic acid can inhibit the growth of dangerous microorganisms on skin and bacteriocins  produced by this acid can kill the bacteria by disrupting the integrity of the cell membrane. 

3# Diminishes Wrinkles- The best way of reducing the early signs of aging, lactic acid penetrates through the epidermis and dermis of the skin. Due to this process the lactic acid helps to increase the cell turnover by exfoliating and sloughing the dead skin cells naturally. 

4# Helps to hold in the moisture- Milk has taken over the beauty industry lately and is a part of many beauty products such as face wash, moisturizers, creams, lotions, etc. Lactic acid helps to improve the natural moisture factor of the skin. It helps to keep it moisturized and improves its moisture holding capacity of the skin.
