Arginine
An amino acid used to gently balance a formula's pH and to soften skin feel, often as a milder alternative to harsher pH adjusters.
What it does
Arginine is a naturally occurring amino acid. In formulas it commonly serves to neutralize acids and bring pH into the target range, and it contributes a conditioning, water-binding quality. It is a gentle, multi-purpose helper ingredient rather than a headline active.
