Rosacea is developed in the dermis (middle) layer of the skin. While the exact cause is unknown, environmental and genetic attributes have been noted. Rosacea shows up, mainly on the face, in the form of small pimples, redness and flushing. In LED light therapy, a red light penetrates the dermis layer, resulting in cell reproduction and reduction of redness. When treated with the Touch Activated LED Mask by SevenSkin Beauty, the visible blood vessels have a 50% – 75% reduction after less than five treatments.
