Everything about AHA
AHA is one of the signature ingredients in COSRX. You probably think of it first as an ingredient to soften skin texture and exfoliate dead skin cells. In fact, AHA has many other skin benefits beyond exfoliation. Let's take a look at various functions of AHA and when it's best to use it.
AHA
More precisely, it's called Alpha-Hydroxy Acids, and it's a type of water-soluble acids that can be easily obtained from plants. Other acids known by AHA include glycolic acid, lactic acid, citric acid, malic acid, and mandelic acid.
Each of these acids has a different molecular structure and size, so they have slightly different functions, but they all have a common function as AHA.

① Exfoliation and Skin Texture Refinement
Every day, our skin naturally undergoes a process called turnover, where old dead skin cells are shed and new ones are replenished. However, as we age or are continuously exposed to UV rays, this natural function diminishes, and old dead skin cells accumulate on the surface of the skin without being shed in time, leading to concerns about rough skin texture.
AHA is great at removing old dead skin cells on the surface of the skin and refining skin texture. It work by breaking down the 'desmosome,' which is the adhesive substance between keratinocytes, weakening the adhesion between cells and promoting exfoliation. Thanks to this function, AHA is great for turning uneven, dull skin into smooth skin in a short amount of time.
② Remodeling
The replacement of old skin cells with new ones is the fundamental mechanism to keep beautiful and healthy skin. AHA has a remodeling effect that reorganizes the skin from both natural aging and premature aging induced by UV exposure. It helps increase the turnover rate of skin cells that have slowed down and speed it up again so that it can be filled with new skin cells.
