Dermal filler products
With the increasing popularity of injectable cosmetic solutions to reverse the signs of aging, there have been a number of dermal filler products in the market since the 80s starting with collagen-based fillers that proved safe for people. Before that, dermal filler substance used paraffin and silicone which had mild to serious health complications and are rarely, if ever, used these days.
Now, aesthetic procedures have discovered a much safer injectable substance in Hyaluronic based dermal filler products, eclipsing collagen fillers that enjoyed widespread use at the start of the 21st century. Fat dermal injections have likewise been popular among people wanting to have younger looks. Whichever dermal filler products are used, statistic from the American Society for Aesthetic Plastic Surgery or ASAPS show significant growth in the use of dermal fillers.
Similar statistics from the UK have not been available but it should be no different. Injectable dermal filler products are a lot safer with none of the risks involved in plastic surgery and considerably cheaper besides.
How They Work
As we age, the skin losses the collage and fatty volume under the skin so that they become thin and wrinkled and the lines produced when we frown or smile become permanent. You can either resort to plastic surgery to remove and stretch sagging skin or use injectable dermal filler products that do a safer, cheaper and more instant job at erasing those lines and wrinkles.
In general, these filers are injected under the skin to produce more volume and plump-up furrows and creases to bring them to the same level as the rest of the skin. The results are instantly smoother skin and less pronounced furrows and creases. Some have permanent results but most are temporary and require regular follow-up sessions with your doctor or cosmetologist to touch-up the dermal filling as they dissipate or get absorbed into the underlying tissues within 3-9 months.
Local topical anesthetics are applied to numb the pain and some tests are done to check on allergic reactions to the dermal filler products.
Collagen-based Dermal Filler Products
Collagen is a naturally produced protein occurring in connective tissues in animals and humans. They comprise the bulk of non-permanent dermal filler products since it was first FDA-approved in the early 80s starting with the Zyderm and Zyplast brands.
The substance is often extracted from cows and figures in many bovine collagen products such as CosmoPlast/CosmoDerm and ArteFil dermal filler products. ArteFill is more of a permanent dermal filler that can last years compared to other collagen dermal filler products that require regular touch-ups with 3-6 month intervals. Collagen extracts from pigs have recently found its way in collagen dermal filler products with the approval of Evolence by the FDA in 2008.
Hyaluronic Acid Based Dermal Filler Products
Like Collagen, Hyaluronic acids are naturally occurring compounds in both animal and human connective tissues, but are polysaccharides or carbohydrates rather than protein. They have proven to be safer than collagen based dermal filler products with manageable or no side effects. And because they have better bio-compatibility, allergy tests can be dispensed with. It is not surprising that hyaluronic dermal fillers like Restylane®, Perlane®, Juvederm® and Hylaform® have overtaken collagen based dermal filler products as the 3rd most popular aesthetic dermal filling substance in the US alone.
