Collagen injections are used to plump up creased, furrowed, or sunken facial skin. It is easily administered and takes approximately fifteen minutes to one hour per session. Sedation is not required and local anesthesia may be included with the injection.
The side effects are temporary throbbing, stinging, or burning for several hours. Faint redness should fade in twenty-four hours, though some individuals may remain discolored for three to ten days. The duration of results is variable due to collagen is gradually absorbed by the body. Therefore, plumping effects may disappear within a few months to one year.
The main risk involved is an allergic reaction to collagen including rash, hives, swelling, or flu-like symptoms. A skin test can be performed before collagen injections to determine whether an allergy exists. Some additional risks are infection and contour irregularities. You should not have collagen injections if you are pregnant or suffering from connective-tissue disease such as lupus or rheumatoid arthritis.
Soft Tissue Fillers
If you want to reduce facial wrinkles and lines, hyaluronic acid may be a good choice as a dermal filler because of its compatibility with the human body. Hyaluronic acid is a natural substance found in your body. It is extracted and reformulated and now has become one of the most popular kinds of injectable soft tissue fillers. Hyaluronic acid is not derived from animal sources. For soft tissue filling use, it is made into a gel form which is injectable. When this gel is injected, it acts like an inflated cushion to support facial structures and tissues that may have lost volume or elasticity due to normal aging. It also brings water to the surface of skin to keep it looking fresh and supple.
In the last few decades, various synthetic forms of hyaluronic acid have been developed and used to correct disorders in the fields of rheumatology, ophthalmology, and wound repair. More recently, synthetic forms of hyaluronic acid are being manufactured for use in facial soft tissue augmentation. Brand names include Captique, Esthélis, Elevess, Hylaform, Juvéderm, Perlane, Prevelle, Puragen and Restylane.
Another type of soft tissue filler is polymethyl-methacrylate, or PMMA.
PMMA fillers contain about 20 percent of tiny PMMA microspheres that are suspended in 80 percent purified collagen gel. A few months after it is injected, the collagen gel breaks down and your body produces its own natural collagen to fill out the space under the skin.
This type of dermal filler, considered semi-permanent, is most often used to treat medium-to-deep wrinkles, folds and furrows, particularly nasolabial folds. It can also be used to fill out pitted scars and to augment thin lips.
When a more permanent solution to facial wrinkles is desired, PMMA is often used instead of collagen replacement therapy or hyaluronic therapy. PMMA has been used for many years in permanent surgical implants. Because of this, your surgeon will likely under-fill on the first treatment, adding more later if needed. PMMA, properly delivered, offers long-lasting results. The only brand of PMMA that is currently FDA approved is Artefill.
