Derived from milk, fruits, or vegetables, it works by gently breaking down dead skin cells on the surface, promoting cell turnover and revealing smoother, brighter skin. Lactic acid is known for its ability to improve texture, reduce the appearance of fine lines, and enhance skin hydration. Additionally, it can help address issues like hyperpigmentation and uneven skin tone, making it a popular ingredient in various skincare products, including cleansers, toners, masks, and serums. It is generally suitable for most skin types, but individuals with sensitive skin may want to start with lower concentrations to minimize the risk of irritation. Regular use of lactic acid can contribute to a more radiant and rejuvenated complexion.
