Lactic Acid

Rating: BEST

It is an alpha hydroxy acid (AHA) derived from milk and is widely used in skincare for its exfoliating, hydrating, and skin-renewing properties. It is known for its ability to promote cell turnover and improve overall skin texture.

Benefits in Skincare:

  1. Exfoliation: Lactic acid helps remove dead skin cells from the surface of the skin, promoting a smoother and brighter complexion. It is gentler than some other acids, making it suitable for sensitive skin.

  2. Hydration: Unlike many other exfoliants, lactic acid has humectant properties, meaning it can draw moisture into the skin and help maintain hydration levels. This makes it beneficial for dry or dehydrated skin.

  3. Improved Skin Texture: Regular use of lactic acid can lead to a more refined skin texture, reducing the appearance of roughness, fine lines, and uneven skin tone.

  4. Collagen Production: Lactic acid can stimulate collagen production, which helps improve skin elasticity and firmness, contributing to a more youthful appearance.

  5. Brightening Effect: By promoting cell turnover and exfoliating the skin, lactic acid can help reduce hyperpigmentation and dark spots, leading to a more even skin tone.

  6. pH Balancing: Lactic acid can help balance the skin’s pH, supporting the skin’s natural barrier function and promoting a healthier complexion.

  7. Anti-Aging Properties: Its exfoliating and hydrating effects make lactic acid an effective ingredient for reducing the signs of aging, including fine lines, wrinkles, and dullness.

Lactic acid is commonly found in a variety of skincare products, including cleansers, toners, serums, and peels. It is typically recommended to start with lower concentrations and gradually increase usage to allow the skin to acclimate, especially for those with sensitive skin. Proper sun protection is also advised when using products containing lactic acid, as AHAs can increase skin sensitivity to UV rays.
