Protective Effects of 

Topical Antoxidants (Skin)





December 2011

Interesting article on cream (Ann Fonfa says she heard of it years ago). Excuse the 'hyped' up title. Good information on eggplant/tomato/pepper-based product. Remember more antioxidants are helpful in reducing sunburn and cancer risk. See article below.

“Dietary glucoraphanin-rich broccoli sprout extracts protect against UV radiation-induced skin carcinogenesis in SKH-1 hairless mice.” Photochem. Photobiol. Sci., 2010, 9, 597’ DOI: 10.1039/b9pp00130a.

This comes from the lab that first looked at broccoli and broccoli sprouts (Johns Hopkins, MD)

Unprotected prolonged exposure to sunlight raises the risk of ultraviolet (UV) radiation to cause or accelerate skin aging as well as skin cancer. Albena T. Dinkova-Kostova, from Johns Hopkins University (Maryland, USA), and colleagues fed broccoli sprout extracts, high in glucoraphanin, a precursor to compounds in broccoli that have been identified as potent anti-carcinogens, to laboratory mice previously exposed to UV radiation.

The researchers found that a daily dose of 10 moles of glucoraphanin inhibited the subsequent development of skin tumors, with skin tumor incidence reduced by 25% and tumor volume by 70%.

Dr. William Grant of the Sunlight, Nutrition and Health Research Center (SUNARC), San Francisco, suggests maintaining a high dietary antioxidant status in order to guard against skin cancer. (posted 6/05)

Protective Effects of Topical Antioxidants in Humans

Dreher F, Maibach H

Curr Probl Dermatol. 2001;29:157-164

Human studies have convincingly demonstrated pronounced photoprotective effects of 'natural' and synthetic antioxidants when applied topically before UVR exposure. Particularly with respect to UVB-induced skin damage such as erythema formation, the photoprotective effects of antioxidants are significant when applied in distinct mixtures in appropriate vehicles.

Topical application of such combinations may result in a sustained antioxidant capacity of the skin, possibly due to antioxidant synergisms. And, since UVA-induced skin alterations are believed to be largely determined by oxidative processes, topical administration of antioxidants might be particularly promising.

In fact, topical application of antioxidants or antioxidant mixtures resulted in a remarkable increase in the minimal dose to induce immediate pigment darkening after UVA exposure and diminished the severity of UVA-induced photodermatoses in humans.

In conclusion, regular application of skin care products containing antioxidants may be of the utmost benefit in efficiently preparing our skin against exogenous oxidative stressors occurring during daily life. Furthermore, sunscreening agents may also benefit from combination with antioxidants resulting in increased safety and efficacy of such photoprotective products.
