What is AHA (alpha-hydroxy acid) ? How to use ?

AHAs are often used to treat a variety of skin issues, such as dry skin, flaking, and uneven skin tone. They can help reduce the appearance of fine lines and wrinkles, and improve the overall health and appearance of your skin. AHAs are found in serums, creams, and lotions, and are often used in combination with other skin care ingredients.

There are many types of AHAs, including glycolic acid, lactic acid, and citric acid. Each type of AHA has a different strength and pH level, and it is important to choose the type and concentration of AHA that suits your skin type and concerns.

AHAs can be effective in improving the health and appearance of your skin, but they can cause side effects such as dryness, irritation, and sensitivity in some people. It is important to use AHAs as directed, and if you are new to AHAs, it is important to start with a low concentration. It is also important to use sunscreen when using AHAs, as AHAs can increase your skin's sensitivity to the sun.

In summary, alpha hydroxy acid (AHA) is a type of organic compound that is commonly used in skincare products to improve the texture and appearance of the skin. AHAs work by exfoliating the skin and are available in several types, including glycolic acid, lactic acid, and citric acid. While AHAs can be effective in improving the health and appearance of the skin, it is important to protect your skin from sun exposure and to use AHAs as directed.
