How to use

Apply 1 pump onto your fingertips (a little goes a long way!) then rub into the skin, massaging into the face and neck until absorbed. Using before your moisturiser and after any water-based products in your routine.


With its unique formulation, C-Deep effectively and efficiently boosts and stimulates the skin's collagen production - an essential protein that gives the skin its youthful firmness and elasticity. In addition, Tetrahexyldecyl Ascorbate stimulates the skin's Hyaluronic Acid production, helping to hydrate and plump skin cells and reduce the appearance of fine lines and wrinkles. The result is a noticeably more youthful complexion.
