Alpha Hydroxy Acids

Other Names: AHA; α-Hydroxy Acid; Fruit Acid

1. Definition Alpha Hydroxy Acids:

Alpha Hydroxy Acids (AHAs) are a group of naturally occurring acids found in fruits, milk, and sugar cane. They are commonly used in skincare products for their exfoliating properties.

2. Use:

AHAs are used in cosmetics to help improve the appearance of skin by exfoliating dead skin cells, promoting cell turnover, and stimulating collagen production. This can result in smoother, brighter, and more even-toned skin.

3. Usage Alpha Hydroxy Acids:

AHAs are typically found in products such as cleansers, toners, serums, and peels. It is important to follow the instructions on the product packaging and start with a lower concentration to avoid irritation. AHAs can increase sun sensitivity, so it is recommended to use sunscreen daily when incorporating them into your skincare routine.
