If hyaluronic acid is the drink, polyglutamic acid is the seal. The INKEY List’s Polyglutamic Acid Serum is a powerful hydration layer designed to lock moisture into the skin’s surface, leaving skin looking plump and smooth — and helping makeup sit better through the day.
Why We Like It: it’s the finishing hydration step — skin feels cushioned, never sticky, and foundation goes on smoother over it.
Best For: dry or dehydrated skin, and anyone whose makeup settles into fine lines by midday.
