I. Introduction

AHA (Alpha Hydroxy Acids) is a water-based acid, that appears in fruits, plants, and lactose. AHA is commonly used in cosmetic product lines for dry skin care, anti-aging, reducing wrinkles, and improving skin. AHA can also moisturize the skin thanks to its ability to hydrate the water, helping the skin stay smoother and brighter.

AHA can work in the epidermis, promoting growth and enhancing the thickness of skin structure, strengthening the quality of elastin and collagen fibers. When in contact with the skin, they quickly remove horny layers and dead cells through cell ion interference, stimulating old cells to quickly peel off and release themselves to the outside.
