Lactic acid is an alpha-hydroxy acid (AHA) that is commonly used in skin care products due to its gentle yet effective exfoliating properties. Here are some of the benefits of lactic acid for skin:

• Exfoliation: Lactic acid helps remove old, dull cells on the skins surface by dissolving the bonds that hold them together, which results in a brighter, smoother, and more even-toned complexion.

• Hydration: Lactic acid is a component of the skin’s natural moisturizing factor (NMF), which is a blend of compounds naturally found in the skin that helps it hold on to moisture. By using lactic acid, you can help improve your skins ability to stay hydrated.

• Anti-aging: Lactic acid stimulates collagen production, which helps to firm the skin and improve signs of aging.

• Improves skin texture: Lactic acid helps to improve the overall texture of the skin by smoothing rough areas and unblocking and cleansing pores.

• Treats hyperpigmentation: Lactic acid can help treat moderate to severe hyperpigmentation, which happens when certain spots on your skin have more than the normal amount of melanin. It can fade out age spots and reduce the appearance of wrinkles and highly visible pores.

Lactic acid is one of the gentlest forms of AHA, so its safe to use on sensitive skin in the right concentrations. It is commonly found in lotions, creams, cleansers, essences, exfoliators, facial treatments, serums, and toners. When using lactic acid, it is important to follow the instructions carefully to ensure the best outcome. It is also important to wear sunscreen when using lactic acid on your skin, as it can cause the skin to be more susceptible to sun damage.
