The Skin Cycle
Skin is the largest organ of the body. It consists of three layers of tissues: the epidermis, the dermis and the subcutaneous layer. The epidermis is the paper-thin outer layer of the skin. The outer layer of the epidermis consists of dead cells that are always flaking or washing off. These are replaced by new cells manufactured in the lower portion of the epidermis, which move upward to the outside of the skin. As they do so, the cells harden and die.
This cycle of cell production and replacement slows as we age. It takes about 28 days for the average, middle-aged adult. As we grow older, this skin cycle slows to about 45-60 days in our 40's and 50's. It can further slow to about 60-90 days in our 50's and 60's. As this process slows, dead cells accumulate on the surface of skin causing sagging and collapse of structure or what we see as lines, wrinkles, and deeper folds. Bacteria can become trapped causing blemishes and breakouts. Discolored and irregular cells can also become trapped causing spots, discoloration, and sometimes more serious skin conditions.
Skin Rejuventation Cycle
Other factors can affect the skin cycle, including: hormones, nutrition, sun exposure, illness, and stress.
When the outer surface of skin is made of newer skin cells, skin feels softer and looks more luminous with less lines and imperfections. By maintaining an average 28-day or faster replacement cycle through healthy lifestyle choices and a regular skin care routine that addresses the basics of skin, your skin will appear smoother and more youthful.
