About
The carnitine salt of pyrrolidone carboxylic acid (PCA) — a humectant and skin-conditioning pairing. Gentle profile, modest evidence.
Carnitine PCA combines L-carnitine, a quaternary ammonium compound normally found in muscle tissue and used topically for skin-conditioning and claimed metabolism-support effects, with PCA (pyrrolidone carboxylic acid), a natural moisturizing factor component and strong humectant. As a salt it delivers both in a single raw material. Both parent components have been reviewed by CIR (as sodium PCA and as carnitine / acetyl-L-carnitine HCl) with favorable conclusions, though this specific salt is less extensively documented. Skin tolerance is generally excellent at typical cosmetic use levels (0.1-2%).
