Photoageing is premature ageing to the skin caused by repeated exposure to UV light primarily from the sun but also from artificial UV sources. ‘Photo’ is derived from the Greek word ‘phos’ which means ‘light’ - therefore, ageing of the skin caused by light.
Photoageing is different from chronological ageing as the damaging effects of UV rays from the sun (or UV tanning resources) alter the normal structures of the skin.
What is Collagen? – The word collagen comes from the ancient Greek word ‘kolla’ which translates to ‘glue’ and the function of collagen is to hold our body and our skin together like glue, providing firmness and strength. Collagen is a protein which is produced by the fibroblasts and is the most abundant protein in the body. In fact, 30% of the protein in our body is collagen and collagen makes up 70% of the protein in the body.
We need collagen in the body to form fibrils and as we age, our collagen production decreases, resulting in weaker connections and then wrinkled, slackened, aged skin occurs.
Advanced Nutrition Programmes approach to the skins need for collagen is to stimulate its natural production and protect it from degradation, rather than creating something with ‘collagen’ in it. Collagen is a very large molecule so its penetration in a product is just not possible via topical skincare and internal versions of ‘collagen’ would feed our body first. We want to focus on its synthesis via fibroblast cell stimulation instead.
