AHAs, or alpha hydroxy acids, are a type of organic acid that can be used to exfoliate the skin. They are water-soluble and work on the skins surface, making them effective for treating surface-level concerns such as enlarged pores, fine lines, and dull complexions. Here are some of the benefits of using AHAs for skin:

• Collagen production: AHAs may help promote collagen production by destroying old collagen fibers to make way for new ones. This can help improve skin elasticity and firmness.

• Anti-aging: AHAs are known for their anti-aging effects, and can help reduce the appearance of surface lines and wrinkles.

• Skin cell turnover: AHAs promote skin cell turnover, which can help reduce skin discoloration by encouraging old, discolored skin cells to turn over.

• Improving skin texture: AHAs can remove rough or flaky skin without causing irritation, reducing the appearance of dry skin, blemishes, and keratosis pilaris.

• Evening out skin tone: In theory, long-term use of AHAs may reduce skin discoloration by encouraging the old, discolored skin cells to turn over. The American Academy of Dermatology recommends glycolic acid for discoloration.

AHAs can be found in a variety of skincare products, such as cleansers, toners, moisturizers, scrubs, peels, and masks. They are generally safe and effective, but it's important to use them as directed and to protect your skin from sun damage when using them.
