POLYGLUTAMIC ACID
Safety grade: A
Polyglutamic acid is a natural amino acid polymer that acts like a moisture magnet for your skin. It works similarly to hyaluronic acid by attracting and holding water to keep skin hydrated and plump.
This ingredient conditions and hydrates the skin by binding moisture to the outer layers, helping to improve skin softness, smoothness, and overall appearance.
