It visibly dimishes hyperchromatic spots and brightens the skin. Additionally it is able to reduce acne lesions and to alleviate melasma on ethnic skin. These tetrapeptides inhibit ultraviolet light (UV)-induced expression of the pro-inflammatory cytokine interleukin-6 (IL-6) by skin epithelial cells and fibroblasts. Furthermore, the tetrapeptides repress the upregulation of matrix metalloproteinase-1 (MMP-1) by skin fibroblasts induced by either direct exposure to UV rays or treatment with media conditioned by UV-treated keratinocytes. The small size and bio-activity of the tetrapeptides render them suitable for use in therapies directed to inflammatory skin disorders and as active ingredients in skin care products.
