The Ultimate Guide to Lactic Acid: Benefits, Uses, and Side Effects

Lactic acid: A Key Ingredient in Skincare and Bodycare Products

If you have ever used any skincare, body care or hair care products, then chances are you have heard of lactic acid. It is a key ingredient in many of these products and is known for its numerous benefits. Lactic acid is a type of alpha-hydroxy acid or AHA, which is derived from milk. In this article, we will explore how lactic acid works, its benefits, and how it is used in various skincare and bodycare products.

What is Lactic Acid?

Lactic acid is a type of AHA that is naturally found in milk and other dairy products. It is made through the fermentation process of natural sugars in milk. Lactic acid is also produced by our muscles when we exercise or engage in physical activity, which causes fatigue and soreness. However, lactic acid in skincare products is derived from non-dairy sources such as sugar beets, corn, and grapes.

How Lactic Acid Works?

Lactic acid works by gently exfoliating the skin, removing the dead skin cells on the surface. This process helps to reveal brighter, smoother and more even toned skin. Lactic acid also stimulates collagen production, which helps to reduce the appearance of fine lines and wrinkles. Additionally, lactic acid has humectant properties, which means that it attracts and retains moisture in the skin. This makes it an effective ingredient for hydration and improving skin texture.
