Lactic acid, derived from natural sources such as milk, has emerged as a versatile ingredient in cosmetics. With mild exfoliating properties, lactic acid promotes cellular renewal, helping to improve the texture and radiance of the skin. Additionally, it acts as a humectant, promoting moisture retention. Its inclusion in cosmetic products aims to soften the appearance of fine lines, promote even skin tone, and offer a healthy glow. Lactic acid is known for being skin-friendly, making it a popular choice in skincare routines for those seeking a more radiant and revitalized complexion.
