AHA is often used to treat various skin issues such as dry skin, flakiness, and uneven skin tone. It can help reduce the appearance of fine lines and wrinkles and improve the overall health and appearance of the skin. AHA can be found in serums, creams, and lotions, and is often used in combination with other skincare ingredients.

There are many types of AHA, including glycolic acid, lactic acid, and citric acid. Each type of AHA has different strengths and pH levels, and it is important to choose the type and concentration of AHA that is suitable for your skin type and concerns.

 AHA can effectively improve skin health and appearance, but it may cause side effects such as dryness, irritation, and sensitivity in some individuals. It is important to use AHA according to the instructions, and if you are not familiar with AHA, it is advisable to start with a low concentration.When using AHA, it is also important to use sunscreen, as AHA can increase the skin's sensitivity to the sun.

In summary, alpha-hydroxy acid (AHA) is a type of organic compound 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 effectively improve skin health and appearance, it is important to protect the skin from sun exposure and to follow the instructions when using AHAs.
