Given the discovery of many antimicrobial defense compounds on the skin which protect against infection , I was wondering if there were any compounds that protect the skin against sunlight in addition to melanin ?
Further, I wanted to know if any such compounds were more effective in dry sweat rather than wet ?
Finally, I wanted to know if skin microflora could play a role in the secretion of sunlight protective compounds ?
Ancient times, people have used different herbs or plant extracts to combat ageing. Curcumin, resveratrol, epicatechin, ellagic acid and apigenin are used in cosmetic formulations to combat skin ageing.
Some injested compounds can help in increasing natural skin protection to sunburn. It doesn't replace suncream but can help. They are the compounds usually found in sun supplements. Some compounds of interest are French maritime bark extract (Commercial name: Pygnogenol), Polypodium leucotomos (a South American fern), Rosemary and grapefruit extract (Commercial name: NutroxSun). Most peer reviewed research on these was funded by the commercial company selling them.
I am working on a topical product that is shown to re-nature the diseased skin, no matter what kind of damage, Acne, Psoriasis, wound, tinea pedis, etc. There is a common deficiency in all dermal diseases. We have shown efficacy in Acne, Psoriasis, onychomycosis, tinea pedis. There is a possibility that applying the same approach can protect the skin from sun damage. The problem is that will require a long-term study. Same reason why we don't know much about skin natural defense. It takes a long, long time to prove anything! We will tackle and expand our studies on psoriasis soon. Hope that we can repeat the great results that we got to date.
