Key Ingredients
Multi-Weight Hyaluronic Acid

With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the lower layers of the skin into the upper layers. This leaves the complexion visibly nourished and supple.

Vitamin B5

Also known as panthenol, vitamin B5 helps the skin to retain moisture, while supporting the regeneration of skin cells for visibly plumper skin.

Natural Moisturising Factors (NMFs)

A unique combination of natural components in your skin (sodium PCA, glycerin, urea, proteins, sugars, 15 different amino acids, lactic acid, and creatine) which bind and hold moisture for optimal skin hydration.

Saskatoon Berry

Packed full of wonder-antioxidants called anthocyanins (pronounced 'ANtho-SYa-nins'), this Canadian superberry can help to block the enzyme which breaks down hyaluronic acid, therefore preserving the skin's natural moisture levels for visible plumpness.
