cellular shape and composition. Eventually the skin cells die and produce the outer layer which resists abrasion and forms a barrier against loss of nutrients and water.

Additionally, skin contains specialized cells. Melanocytes are one example, and are the cells responsible for producing melanin which gives the skin, hair, and eyes color, and helps provide protection from the UV portion of sunlight. There are also glands that produce oil and sweat. Oil glands, or sebaceous glands, usually surround a hair follicle and are often associated with acne. Sweat glands release water mixed with salts.

Skin is more easily damaged, repairs more slowly, and sags and wrinkles as the elastic fibers decrease and the hypodermis loses fat.

Skin cells lose their regenerative ability, and the buildup of dead skin cells dulls the appearance of the skin. The accumulation keratin can cause skin to take on a rougher appearance.

Studies have shown that the majority of Americans are dehydrated at any given time. Insufficient water consumption, coupled with the diuretic effects of caffeine, cause much of the cumulative damage linked with aging of skin. Additionally, when diet and hydration are considered, you must also think about alcohol intake. Reducing the amount of alcohol helps in several
