Skin care is vital to many people's daily beauty and health routines. Among the essential ingredients that play a prominent role in improving the health and beauty of the skin, we find fatty acids. These acids come in different types and are found in many skin care products , and in this article we will discuss their role and importance.

Definition of fatty acids:

Fatty acids are organic compounds composed of long chains of carbon and hydrogen atoms, and are characterized by their ability to be effectively absorbed into the skin. These acids are divided into several main categories, including:

1. **Essential fatty acids (omega-3 and omega-6):** They play an important role in restoring the skin barrier and maintaining hydration. These acids can be found in oils such as fish oil and flaxseed oil.

2. **Alpha hydroxy acids (AHAs):** They are used to exfoliate and lighten the skin. Examples include glycolic acid and lactic acid, which are found in products such as facial scrubs .

3. **Beta Hydroxy Acids (BHAs):** They are used to control oil and combat acne. Salicylic acid is one example of this type of acid.

4. **Hyaluronic acids (HA):** maintains skin hydration and fills wrinkles. Hyaluronic can be found in skin care serums and moisturizers.

The role of fatty acids in skin care products:

1. **Skin exfoliation:** Acids such as AHAs and BHAs are used to remove dead cells and stimulate the growth of new cells, which improves the texture of the skin and makes it appear fresher.

2. **Moisturizing the skin:** Fatty acids such as alpha hydroxy acids and hyaluronic acids retain moisture in the skin, making it appear smoother and more elastic.

3. **Anti-acne:** Acids such as salicylic acid help clean pores and limit the spread of acne.

4. **Reducing wrinkles:** Acids contribute to improving skin elasticity and significantly filling wrinkles.

5. **Skin lightening:** Acids are used to reduce pigmentation and dark spots on the skin.
