A new study by a branded ingredient (GliSODin) containing superoxide dismutase (SOD) showed significant reduction in susceptibility to sunburn.

In the double-blind, placebo-controlled study, UV skin burn was induced on the inner forearms of healthy subjects before supplementation with either placebo or GliSODin. The color of the skin was measured and changes in skin due to inflammation were assessed.

GliSODin supplementation resulted in an increase in the minimum exposure to UV rays necessary to produce skin burn. In particular, phototypes II (people with fair skin) required eight times greater exposure than that of the placebo group. Further, the redness induced by the skin burn decreased more quickly in the GliSODin group and the increase in the number of capillaries in small blood vessels, demonstrating a reduction in inflammation, was higher in the GliSODin group compared to placebo.

According to researchers, "This study confirms the efficacy of GliSODin in the prevention of the consequences of oxidative stress resulting from exposure to the sun. The efficacy is of particular interest for phototypes II (fair-skinned) that represent a major part of the consultations in dermatology."

The study, which included 50 participants, was conducted by researchers at Center Hospital University, Besancon, France, and was presented at the Annual Congress of Dermatological Research meeting in Brest, France in May.
