Stretch marks happen when the collagen beneath the skin’s uppermost layer breaks down and stretches out.
The body’s natural ability to repair supporting connective tissue and maintain hydration of cells diminishes after age 25.
By around 40 years of age, your body stops manufacturing collagen. This results in fine lines and wrinkles, loss of skin elasticity, poor hair, nail and joint quality.
Up to 30% of all protein in the body is collagen
Up to 70% of the protein in connective tissue is composed of collagen
About 80% of the dermis — the part of your skin that’s under the epidermis (outer layer) — is collagen.
Collagen is the most abundant protein in the body.
Applying creams and serums that contain collagen has zero effect upon actual skin collagen levels – the protein molecules are too large to penetrate the skin. Topical products can however help to boost collagen in the skin – look for products containing vitamin c, retinoids, peptides & AHA’s.
