Lactic acid is a type of alpha-hydroxy acid (AHA) that is commonly used in skin care products. It is derived from milk and is known for its exfoliating properties. The benefits of lactic acid in skin care include:
- Exfoliation: Lactic acid helps to remove dead skin cells, leading to a brighter and smoother complexion.
- Hydration: Lactic acid can help to hydrate the skin by increasing the skin’s natural moisturizing factor (NMF).
- Brightening: Lactic acid can help to improve the overall tone and texture of the skin, making it look brighter and more radiant.
- Anti-Aging: By increasing cell turnover, lactic acid can help to reduce the appearance of fine lines and wrinkles.
- Treating hyperpigmentation: Lactic acid can help to reduce the appearance of dark spots and hyperpigmentation.
It is important to note that lactic acid can cause some irritation and dryness, especially in higher concentrations. It is important to start with a lower concentration and build up as your skin adjusts, and to always use a sunscreen when using products containing lactic acid.
