Human and mammalian skin undergoes a variety of changes associated with chronological aging. Various environmental factors, disease states and genetic disorders may accelerate both the appearance of aging skin and also the structural and functional changes associated with aging skin. Ultraviolet radiation from the sun is one of the classic known and well-defined means of accelerating or worsening the aging of the skin and this is frequently termed photoaging. Other environmental factors, such as oxidative stress, free radicals, environmental toxins such as ozone and cultural customs or habits such as tobacco smoking are other known probe accelerators in photo aging skin. A wide variety of other factors known and unknown contribute to accelerated or premature aging of the skin. This invention discusses methods where electromagnetic radiation, in particular, light, can be used to photobiomodulate the activity of living cells to delay, diminish, retard or even reverse the structural and functional effects of aging of the skin and other living cells and tissues. In particular methods described for improving the appearance, structure, function of aging skin, including up and down regulating the genotypic markers for the phenotype of aging skin.

The invention provides the use of silica for cosmetic and/or medical treatment of skin, including improving and enhancing the skin-barrier, anti-aging treatment and photo-protective treatment. The invention is based on the finding that silica exhibits a multi-faceted biological effect useful in the cosmetic and/or therapeutic treatment of skin for the above purposes. Specifically, it has been shown that silica induces markers (involucrin, filaggrin and transglutaminase-1) for skin barrier formation in keratinocytes, induces collagen expression in dermal fibroblasts and inhibits UVA-induced up-regulation of photo-aging markers (matrix metalloproteinase MMP-1 and cytokine IL-6).

The present invention relates to a composition for the skin whitening and wrinkle improvement, comprising an extract of Vaccinium uliginosum as an active ingredient.

Thus, the extract will be useful for the prevention of skin photo aging caused by ultraviolet radiation, the enhancement of skin whitening and the improvement of wrinkles. In addition, the Vaccinium uliginosum extract is suitable to use as a component for improving skin wrinkles in cosmetics, foods and drugs, because the Vaccinium uliginosum extract can achieve the effect of improving skin conditions, even when it is applied to the skin or used internally.
