Anti-aging addresses how to prevent, slow, or reverse the effects of aging and help people live longer, healthier, happier lives. It includes scientific research and applications in genetic engineering, tissue engineering, and other medical advances, e.g., finding treatments and cures for Alzheimer’s disease. It includes anti-aging psychology, e.g., coping skills for resiliently handling change, stress, and aging. Life extension is the part of anti-aging focused on living as long as possible.

The anti-aging marketplace includes nutrition, physical fitness, skin care, hormone replacements, vitamins, supplements, and herbs. Alternative medicine and holistic approaches have often been an incubator for approaches initially shunned by traditional medicine.

Your Skin's Anatomy

skin consists of 3 layers - the epidermis and dermis, and subcutaneous tissue.

1st Epidermis: The epidermis is located on the outer layer of the skin and can be seen visibly on the surface. The epidermis is the thinnest of layers, but also ironic is the obstacle of grate protection for the whole body. The epidermis is the thinnest on the eyelids to 05 mm and the thickest on the palms and soles at 1.5 mm. The thickness of the epidermis varies for different types of skin. The epidermis also contains the pigment melanin, the skin of his color.

There are 5 delicate layers of cells that make up the entire epidermis. From the bottom (most internal) to top (most external) the layers are named:

stratum basal

stratum spinosum

stratum granulosum

stratum licidum

stratum corneum

Approximately all twenty-seven days new skin is regenerated by the skin cell turnover. The lower layer, also known as the stratum corneum, is where new skin cells originate. As cells are created they crowd and are pushed upwards in the next higher level. As the cells in the upper layers, flat and they finally die. How old, dead skin cells reach the outer surface, they are replaced by Slough off the upward move cells them.

2nd Dermis: The Middle Layer support of the epidermis is known as the dermis. The dermis is a complex matrix of the hair follicles, Blutgefae, and tallow (oil) glands.

The dermis, contains elastic fibers known as the protein collagen and elastin fibers called fibroblasts, and "glue like" cells synthesize that collagen and elastin together, to the skin elasticity, support and suppleness.

Elastin how the word is the elastic protein that works with collagen in the dermis, the skin of crucial importance snap or spring, which would be the main corporate structure. Diminish our elastin in skin over time, causing the skin to loosen and sag.

The dermis layer is also responsible for wrinkles. Collagen, the fountain of youth is the most abundant protein, of which 75% of the skin. Overtime, environmental factors and aging to reduce the body's ability to manufacture collagen.

3rd Subcutaneous tissue: Subcutaneous tissueis the layer of fat and connective tissue with graeren Blutgefae and nerves. This layer works to regulate the temperature of the skin itself and the body. The thickness of this layer varies throughout the body and from person to person.
