Sun Damage or Solar Elastosis affects people who have had long term sun exposure. Excess exposure to sun without protection can result in many unwanted skin issues, such as uneven skin tone and texture, brown spots, freckles, wrinkles, and sometimes skin cancer. The sun delivers UVA and UVB radiation, both of which penetrate the epidermis (top layer) and dermis (deep layer). Your skin produces a melanin pigment as a defense to absorb UV radiation. UVB rays can lead to sunburns, but UVA rays penetrate deep into the dermis, where the skin’s collagen and elasticity lives. When this layer gets attacked by sun damage, free radicals are released and cause harm to your skin cells’ DNA, causing those unwanted skin problems.
In sun-damaged skin, there is generally increased pigmentation which can vary in color from yellow to brown and can be uniform or patchy. As it gets more severe, the skin takes on a yellow color with the development of wrinkles and furrows.
