Skin Hazards from Sun Exposure Resource: cancer/ss/slideshow-sun-damaged-skin

The Dark Side of Sun Exposure  Effects of sun exposure put us at higher risk of cellular damage, early wrinkling, age spots, actinic keratoses, and skin cancer -- including the most serious type, melanoma.

Suntan  Tanned skin may be revered as beautiful, but that golden color you see is the result of injury to the epidermis, the top layer of skin.  To prevent sun damage, use a sunscreen of SPF 30 or higher when outdoors.

Sunburn (1 st Degree)  Sunburn is skin damage from the sun's UV rays. Most sunburns result in redness, heat to the touch, and mild pain, affecting only the outer layer of skin (first degree burns).

Sunburn (2 nd Degree)  A second degree burn – damaging deep skin layers and nerve endings - - is usually more painful and takes longer to heal. It's characterized by redness, swelling, and blistering

Wrinkles  The sun's rays make skin look old and wrinkled years before it should. More than 80% of the signs of skin aging in adults are the result of the tans they had as teens before the age of 18

Uneven Skin Tone  Too much sun also causes irregular coloring or pigmentation of the skin. Some areas of the skin appear darker, while others look lighter.

Freckles  Flat, pigmented spots on the skin, freckles are usually found on sun- exposed areas of the body.

Melasma  Melasma (or chloasma) is characterized by tan or brown patches on the cheeks, nose, forehead, and chin.

Actinic Keratosis  The small, scaly red, brown, or skin-colored patches caused by too much sun exposure commonly occur on the head, neck or hands, but can be found elsewhere on the body. They're the early beginnings of skin cancer

Squamous Cell Carcinoma  This nonmelanoma skin cancer may appear as a firm red nodule, a scaly growth that bleeds or develops a crust, or a sore that doesn't heal.

Basal Cell Carcinoma  The most common form of skin cancer, basal cell carcinoma is the most easily treatable and least likely to spread, though it can damage surrounding tissue.

Melanoma  Melanoma is not as common as other types of skin cancer, but it's the most serious and potentially deadly. Possible signs of melanoma include a change in the appearance of a mole or pigmented area.

Cataract  A cataract is a cloudy area in the lens of the eye that blocks the passage of light to the retina
