Dynamic wrinkles: Injectable facial fillers
Aesthetic Medicine Dubai | 12 September 2020
The use of injectable facial fillers is one of the fastest growing areas in the field of cosmetic surgery. Many advances in have been made in the last 5 years that have led to safer, more predictable and longer lasting fillers.
As one ages, the face loses volume. This creates more prominent wrinkles and skin folds while features become less distinct. Dynamic wrinkles caused by facial movement such as smiling and frowning appear. Injectables were designed to subtly reduce these signs of aging.
Most fillers work by restoring the volume of a part of the face or filling the lip or wrinkle and are gradually digested by the body. Hyaluronic Acid Fillers: These were the first of the new fillers to be FDA approved. Hyaluronic acid is a naturally occurring carbohydrate which occurs in skin. It is a clear gel with a thick consistency. Since skin testing is not required, injections may be done on the same day as the initial consultation. Manufacturers have manipulated particle size (thickness) and crosslinked molecules to offer both normal and longer duration products.
Juviderm and Teosyal are examples of normal duration products that are injected in more superficial lines and have easier flow characteristics. Juvederm Voluma and Teosyal Redensity II are examples of longer duration products are usually injected into deeper lines and folds.
The newest advance has been the addition of local anesthetic, Lidocaine, to the filler to reduce discomfort upon injection.
