Lactic acid is a popular ingredient in skincare products, known for its exfoliating and brightening properties. It is a type of alpha hydroxy acid (AHA) that is derived from milk and other natural sources. In this article, we will explore what lactic acid is, how it works on the skin, its benefits, how to use it, and some popular products that contain lactic acid.
What Is Lactic Acid?
Lactic acid is a type of AHA, a group of acids that are commonly used in skincare products for their exfoliating and skin-renewing properties. Lactic acid is derived from milk, but it can also be produced synthetically. It works by breaking down the bonds between dead skin cells on the surface of the skin, allowing them to be sloughed off more easily. This helps to reveal smoother, brighter skin underneath.
How Does Lactic Acid Work?
Lactic acid works by exfoliating the skin, which means it helps to remove dead skin cells from the surface of the skin. This process helps to unclog pores, reduce the appearance of fine lines and wrinkles, and improve skin tone and texture. Lactic acid is also known to help increase cell turnover, which can lead to a more youthful-looking complexion.
The Benefits of Lactic Acid in Skincare
There are several benefits to using lactic acid in skincare products. Some of the most notable benefits include:
- Exfoliation: Lactic acid helps to remove dead skin cells, resulting in smoother, brighter skin.
- Hydration: Lactic acid is a humectant, which means it helps to attract and retain moisture in the skin.
- Brightening: Lactic acid can help to lighten dark spots and hyperpigmentation, resulting in a more even skin tone.
- Anti-aging: Lactic acid can help to reduce the appearance of fine lines and wrinkles, leading to a more youthful complexion.
How to Use Lactic Acid in Your Skincare Routine
Lactic acid can be found in a variety of skincare products, including cleansers, toners, serums, and masks. When using lactic acid products, it is important to start slowly, especially if you have sensitive skin. Begin by using the product once or twice a week and gradually increase the frequency as your skin becomes accustomed to it. It is also important to wear sunscreen during the day when using lactic acid, as it can make the skin more sensitive to the sun.
