Facial fillers are products such as collagen, hyaluronic acid and calcium hydroxyl apatite that rejuvenate facial skin by reducing or eliminating wrinkles, raising scar depressions, enhancing lips and replacing soft-tissue volume loss through facial injections. With age, our skin becomes more susceptible to wrinkles and sagging. Exposure to sun and years of muscle movement (squinting, chewing, smiling) contribute to tissue breakdown of the skin. Facial filler injections are temporary and administered through a few tiny facial injections on specific areas of the face. Various types of facial fillers are available, each is designed with one or several purposes, such as wrinkle reduction and lip augmentation. Facial fillers will increase the volume of creases and folds in the face in areas that have lost fat and collagen as we age. Hyaluronic acid is the natural filler substance in your body. The average length of filler injections is about 10 to 20 minutes per session, depending on the individual and the amount of areas being treated. Dermal filler injections require very minimal downtime, allowing patients to return to work and their normal activities directly following treatment. Yet for the first 24 hours, individuals may be instructed by the cosmetologist to refrain from strenuous activities and excessive sun or heat exposure. In general, the results from most injectable fillers are temporary, commonly lasting from a few months to about a year.
