Potassium PCA

Description

Potassium PCA (Pyrrolidone Carboxylic Acid) is a naturally occurring humectant derived from amino acids found in human skin. This water-soluble ingredient plays a crucial role in maintaining skin hydration and supporting the natural moisturizing factor (NMF) of the skin. Potassium PCA has the ability to attract and retain moisture, helping to keep the skin plump and hydrated.

In skincare formulations, Potassium PCA is valued for its excellent moisturizing properties and its ability to enhance the skin's barrier function. It has a low molecular weight, allowing for easy penetration into the skin's upper layers. This ingredient is particularly beneficial for dry, dehydrated, or sensitive skin types.

Potassium PCA is known for its compatibility with various skin types and its non-irritating nature. It can be effectively combined with other hydrating ingredients to create synergistic effects. In addition to its moisturizing benefits, Potassium PCA may help in reducing transepidermal water loss (TEWL) and improving skin elasticity. It is commonly used in a wide range of skincare products, including serums, moisturizers, and toners, typically at concentrations between 1-5%.
