Detailed answer

Lactic acid is an alpha hydroxy acid (AHA) that helps in exfoliating the skin. By gently removing dead skin cells and unclogging pores, it can help reduce blackheads. Lactic acid also has antibacterial properties that can minimize the occurrence of acne and breakouts. However, it is important to use a lactic acid cleanser appropriately and in moderation, as excessive use can cause skin irritation and dryness. It is recommended to start with a lower concentration and gradually increase if tolerated well. It is also advisable to use a moisturizer and sunscreen while using lactic acid cleansers to protect and hydrate the skin.
