Aging Changes in Skin

Aging changes in the skin show is almost common signs and is suffered by everyone, as they grow older. These aging signs include wrinkles, thinning of skin, dryness, high sensitivity, freckles and sometimes pigmentation etc.

Skin is supposed to be the most visible signs of aging. Exact indication of increasing age includes wrinkled and sagging skin, whitening or graying of the hair.

Skin protects us from the environmental pollution. It regulates the body temperature, by maintaining fluid and electrolyte balance.  Skin bears the receptors for sensations such as touch, pain, and pressure.

Skin is made up of many layers; it can be divided into three main layers. The outer layer is called epidermis, which is made up of skin cells, pigment, and proteins. The middle layer is called dermis and is made up of blood vessels, nerves, hair follicles, and oil glands. It is the dermal layer that provides nutrients to the epidermal layer. Each layer of skin comprises of connective tissue with collagen fibers. These fibers maintain the elasticity of skin and provide flexibility and strength to the tissues.

Skin changes are due to environmental factors, genetic mutations etc. The major factor, effecting skin is sun exposure. The intensity of impact can be evaluated by comparing areas of the body that have regular sun exposure and areas that remain protected.

Skin pigments are responsible for protection against sun as well as other factors.  Fairer individuals show more aging skin changes as compared to individuals with darker skin because darker skin has more pigments.  As we age epidermal layer becomes thin.  But the number of cell layers remains same.  The count of pigment containing cells or melanocytes diminishes, but increasse in size. This causes thinning, pale, and translucent effect.  Alterations in the connective tissue shrink the strength and elasticity of skin.
