A humectant moisturizing amino acid that is a part of the skin's Natural Moisturizing Factor. It helps to retain water on the skin’s surface and is slightly acidic, thereby helping to balance the pH of a skincare product.

Aspartic acid is a non-essential amino acid. Amino acids are the building blocks of all proteins in our body.
In skincare, aspartic acid (or its ionized form, aspartate) is used as a humectant moisturizing ingredient due to its ability to retain water.
Aspartic acid, as the name suggests, is mildly acidic, which makes it useful as a pH adjuster towards slightly acidic pH, similar to the pH of the skin. The proper pH also protects the product from degradation and oxidation.
