Photoaging is the primary cause of premature skin aging. UVA and UVB lights from the sun as well as fluorescent and tanning lamps produce extensive damages to the skin. They cause skin redness and sunburn, produce free-radicals, damage skin collagen and elastin, stimulate the production of melanin (black pigment), cause wrinkles, skin sagging and other visible signs of aging. Excessive UV exposure also causes DNA mutations, and promotes immunosuppression and the production of cancerous cells.
Dr. Jeff sunscreen products protect the skin from UV damages by absorbing, reflecting and scattering UV rays. They also contain antioxidants to counteract free radical damages as well as herbal extracts to hydrate and nourish the skin.
