Hyaluronic Acid and Its Use for Skin Rejuvenation

This is the authors' abstract. We don't add key points for this paper.

The skin envelopes the total surface of the body and it is made up of the epidermis, an epithelial tissue of ectodermal origin; by dermis, a conjunctive tissue of mesodermal origin, which serves as sustainment and is responsible for its nutrition; and by the hypodermis or adipose tissue. This last one is a special type of conjunction in which there is a predominance of adipose cells (adipocytes), specialized in storing lipids in the form of triacylglycerol (TAG); non-polar, hydrophobic and water-insoluble substances. It embodies the organism's main energy reservoir. And its regulation ensues by nutrients and afferent signals of the neural and hormonal systems.
