Polyglumtamic acid

Polyglutamic acid is a powerful amino acid known for its exceptional ability to hold up to 5000 times its weight in water, making it an advanced hydration ingredient in skincare. It works by forming a lightweight moisture-binding film on the skin’s surface, helping to lock in hydration and prevent water loss. In addition to delivering intense, long-lasting moisture, polyglutamic acid helps boost the production of the skin’s natural moisturising factors, improving overall hydration levels and skin resilience.

Hyaluronic acid

Hyaluronic Acid molecules have the unique ability to carry a 1,000 times their weight in water, more than any other biological substance. Hyaluronic Acid is also a “smart nutrient” as it can adjust its moisture absorption rate based on the humidity – relative to the season and the climate. This improves your skin’s moisture content whilst at the same time strengthening your skin’s barrier, helping your skin to look and feel softer, smoother, and plumper.

Clinically proven

In clinical testing, 95% of users reported visibly improved hydration, with skin feeling noticeably softer, smoother, and more plump. This boost in moisture helps enhance overall skin texture and vitality, leaving the complexion looking healthy, refreshed, and radiant.
