Description
Discover powerful hydration with The INKEY List Polyglutamic Acid Serum. The serum is designed to intensely hydrate the skin for a smoother, replenished appearance.
The serum is powered by a 3% polyglutamic acid complex which forms a film across the skin’s surface to lock in up to four times more moisure than hyaluronic acid. 2% Invisaskin plumps the skin with hydration, minimising the appearance of fine lines. Creating the perfect makeup canvas, the formula leaves skin with a dewy, glowing finish.
