PCA
Ingredient Info
PCA (pyroglutamic acid) is a naturally occurring amino acid derivative that acts as a humectant, helping skin retain moisture. In skincare, it's valued for its hydrating properties and is often used in serums and moisturizers to improve skin softness and suppleness.
Benefits
- Humectant that draws moisture into the skin
- Supports skin hydration and barrier function
- Lightweight ingredient suitable for most skin types
Science: Research shows manganese-complexed PCA (MnPCA) enhances hair follicle growth markers by increasing growth factor receptor activity and promoting key proteins like versican and VEGF in dermal papilla cells. PCA itself has a strong safety profile as an endogenous skin compound with minimal sensitization risk.
