New study supports antioxidant supplements for ageing skin

Taking a dietary supplement containing coenzyme Q10 and a selection of antioxidants and minerals can decrease skin roughness and fine wrinkles, according to a new study.

In the study, 60 female subjects were randomly assigned to either the supplement or a placebo (1). According to the researchers, the depth of skin roughness and fine wrinkles were not significantly different between placebo and treatment group at the beginning of the study, but by the end of week 4 there was a significant reduction in the treatment group. By the end of the study after 12 weeks, skin roughness and fine wrinkles had reduced by 21.22 %, compared to a 1.7 % improvement in the placebo group.

A reduction in pore size, skin roughness and fine wrinkles, was seen by those in the treatment group at a significantly higher level than those taking the placebo, but there were no perceived changes in pigmentation levels.

The supplement, taken once daily, contained antioxidants such as coenzyme Q10, beta-carotene, green tea extract and vitamin E acetate as well as minerals (zinc and selenium). The researchers hypothesized that coenzyme Q10 helped fight oxidative damage preventing DNA degradation and collagen destruction. In addition, vitamin E acetate might also help to reduce collagen degradation and the minerals zinc and selenium might help to support the cell’s own antioxidant enzyme SOD (superoxide dismutase).
