Lactic acid is an alpha hydroxy acid (AHA) derived from milk and fruit sugars. It is widely used in cosmetics for its exfoliating and hydrating properties. Lactic acid helps to gently exfoliate the skin, removing dead skin cells and promoting cell turnover. This leads to smoother, brighter skin and can help reduce the appearance of fine lines, wrinkles, and hyperpigmentation.

Commonly found in serums, peels, and cleansers, lactic acid is suitable for all skin types, including sensitive skin, due to its mild nature compared to other AHAs like glycolic acid. It also helps to improve the skin’s natural moisture factor, keeping it hydrated and plump.

Benefits of Lactic Acid in Cosmetics

1. Gentle Exfoliation:
   • Removes dead skin cells and promotes cell turnover for smoother, brighter skin.
2. Reduces Fine Lines and Wrinkles:
   • Helps to minimize the appearance of fine lines and wrinkles by promoting collagen production.
3. Improves Skin Texture:
   • Enhances skin texture by smoothing rough patches and evening out the skin tone.
4. Hydrates and Plumps:
   • Increases the skin’s natural moisture factor, keeping it hydrated and plump.
5. Reduces Hyperpigmentation:
   • Helps to lighten dark spots and even out the skin tone by promoting a more uniform pigmentation.
6. Mild and Suitable for Sensitive Skin:
   • Less irritating than other AHAs, making it suitable for sensitive skin types.
7. Boosts Skin Radiance:
   • Improves overall skin radiance by removing dull, dead skin cells and revealing fresher skin underneath.
