A primary response to the sun’s ultra violet B (UVB) light is erythema solare which is the most common acute sunlight induced damage to cells. There is increasing research showing that antioxidants such as carotenoids and tocopherols protect against damaging photo – oxidative reactions and may be supportive in preserving healthy skin. Carotenoids are types of antioxidants that are present in human skin and contribute to ultra violet ( UV ) light protection. Natural carotenoids have been shown to protect the ski n from DNA damage under exposure to the sun better than synthetic lycopene. Tomato fruit extract contains a natural source of the carotenoid lycopene as well as other phytonutrients like phytoene and phytofluene that help protect against cellular damage through their ability to absorb UVA and UVB light.
Premature aging of the skin is measured by parameters such as roughness, scaling, smoothness, and wrinkling of the skin. Lycopene and α – tocopherol support the skin’s defenses to environmental stress and help to maintain the skin’s ability to protect against photo – aging. The presence of lycopene in the skin may also correlate to decreased roughness of the skin surface. † Research has shown that volu nteers with higher lycopene levels in their skin were shown to have less skin roughness as measured by skin imaging lines and wrinkles. Lycopene supplementation was also shown to support skin density and thickness.
