According to a recent article in the February issue of Archives of Dermatology, “dermal fillers” containing hyaluronic acids seem to promote collagen production.  Hyaluronic acid is a natural compound found in skin and connective tissue.  When injected, its molecules bind to water in the skin “hydrating and firming” its structure.

NASHA (non-animal stabilized hyaluronic acid) injections promote collagen production through several mechanisms:

• Stimulation of growth factor
• Inhibition of collagen breakdown
• Mechanical stretching of fibroblasts (cells that secret collagen)

The physical streching of fibroblats will induce production of compounds which promote collagen production and suppress chemicals that breakdown the skin’s cell structure thus, over time will repair and prevent further damage to the skin.

Note: hyaluronic acid rapidly diminishes as we age, and is directly associated with dehydration and wrinkles.

The FDA is warning consumers about certain products widely used to numb the skin during or after common cosmetic procedures.  Topical anesthetics in gel or cream form are usually applied to lessen a patients discomfort during these common procedures.  These seemingly harmless topical numbing creams may actually be life threatening if administered incorrectly, two young women have already died.

Look out for: lidocaine, tetracaine, benzocaine, and prilocaine.  Some of these products are prescribed and some are available over the counter, specific doses do in fact numb the skin, however; an overdose can become toxic and may cause seizures, convolutions, comatose and even death.  If you are currently using any of these products you should consult with a doctor to prevent possible misuse.
