Prevent Sun Damage Beyond Sunscreen with Topical Antioxidants

by Marie Veronique

We’ve discussed how UVB rays could harm skin via direct DNA damage. The subsequent chromosomal alterations and mutations can initiate skin cancers, particularly the squamous or basal-cell types associated with UVB. Even if we use a non-nano zinc oxide sunscreen daily to block UV rays, sunscreen alone just does not provide complete protection.

Breakthroughs in Sun Protection: Understanding UVB

by Marie Veronique

UV exposure is responsible for 90% of human nonmelanoma skin cancer. Of the UV light reaching the earth, 90% of the waves are UVA lengths (320-400 nm) and only 10% are the shorter UVB wavelengths (280-320 nm). Both UVA and UVB are studied for their skin cancer-causing potential, however focus has been on UVB. This is at least partially because UVB is considered a  complete carcinogen—a substance able to initiate, promote and progress the development of skin cancer.
