Lactic acid is a type of alpha hydroxy acid (AHA) that is naturally found in milk, fruits, and vegetables. In skincare, it is commonly used as an exfoliant to remove dead skin cells, improve skin texture, and brighten the complexion. Lactic acid can be produced from a variety of carbohydrate-rich starting materials, such as sugar beet, corn, or molasses.

• Exfoliation: Lactic acid works by breaking down the bonds between dead skin cells, allowing them to be gently removed from the surface of the skin. This can help to reveal smoother, brighter skin.

• Hydration: Lactic acid is a humectant, meaning it can help to draw moisture into the skin and improve skin hydration. This can be especially beneficial for those with dry or dehydrated skin.

• Anti-aging: Lactic acid can help to stimulate collagen production in the skin, which can improve the appearance of fine lines and wrinkles.

• Improvement in hyperpigmentation: Lactic acid can also help to fade dark spots and other forms of hyperpigmentation by gently exfoliating the skin and promoting cell turnover.

• Gentle: Compared to other AHAs, lactic acid is one of the gentlest and is less likely to cause irritation or sensitivity.

Overall, lactic acid can be a beneficial ingredient in skincare, especially for those looking to improve skin texture and hydration. However, as with any skincare ingredient, it is important to use it properly and in the correct concentration to avoid any potential side effects.
