Collagen Crème Serum helps to firm and smooth the appearance of the skin at any age. Collagen does its restructuring work best at night, during alpha sleep, but it can also be applied in the morning. Crème Serum contains 15% pure marine (non-shark) Collagen, plus MSM, Hyaluronic acid and plant extracts to amplify the effect. Contains nut oil. May not be suitable for people with a fish allergy.
