Human skin requires some sunlight for optimal health and luminosity, yet excessive solar exposure can lead to premature ageing and skin cancer.

Healthy skin glows with brilliance. This radiance can be recreated and enhanced by a complex of metallic oxides and pigments, including melanin, zinc and iron oxides which also act as visible skin perfectors and pre-emptive solar protectors.

Proactive strategies for solar protection include topical Pre-Vitamin D, which is converted to Vitamin D on exposure to UV light, and Acetyl Tetrapeptide, which supports thermal protection.
