SEM of Human Skin. The top layer of the epidermis is composed of flattened, dead skin cells that form the surface of the skin. The dead cells from this layer are continuously being shed and replaced by cells from the living epidermal layer below it (red). The lowest layer (not seen here) is the dermis. The skin is the body's largest organ, accounting for around 15% of the body's weight.


The toned, radiant plumpness of young skin is due to its high collagen and elastin content. At 18, almost 80% of the dermis, the living layer of the skin, is made up of collagen. But things go south pretty quick after that. Generally we lose 1.5% of our collagen each year, leaving our skins wrinkled and prune-like when we get to 90.#DrinkGoldCollagen

Why does our skin seem to change as we get older? And what can we do to prevent this? The answers are to be found deep below our skin’s surface, in the dermis, the living layer of cells and connective tissues that generate the outer, visible epidermis.#DrinkGoldCollagen

Chemical peel is a noninvasive procedure which results in improvement of epidermis condition and often also of dermis condition. In this purpose we use the influence of various chemical substances (chemical peel) or mechanical (microdermabrasion) or physical processes (CO2 laser, nitrous oxide, liquid nitrogen).


Chemical peels are broadly defined by the depth of damage in the skin that they produce. They are categorized as superficial, medium, and deep. Superficial peels do not damage skin below the epidermis, the most superficial skin layer. Medium peels may reach to the superficial layer of the dermis, the deeper layer of the skin. Deep peels generally reach the deeper layers of the dermis.
