Bruising often a result of skin having lost its fat padding and becoming more susceptible to injury. Some drugs may cause bleeding under the skin. Bruises that persist should be examined by a dermatologist. Wrinkles changes in the elastic tissue from exposure to sunlight, effects of gravity, or motion factors in the skin. A dermatologist can treat wrinkles with dermatologic surgery.
Skin diseases more common in older people include shingles, leg ulcers, and seborrheic dermatitis.
To avoid skin damage from sun exposure, always use a sunscreen with an SPF rating of 15 or higher, a hat with a brim, and protective covering of arms and legs. Don t deliberately sunbathe, and limit sun exposure during the 10 AM to 4 PM hours of greatest sun intensity. Avoid deliberate tanning in tanning salons or under sun lamps. If your skin is already sun damaged you can still benefit from these measures. The skin damage caused by long-term cigarette smoke is avoided by smoking cessation.
