Dermal Fillers are a gel containing hyaluronic acid that is injected into or below the skin by a healthcare professional to smooth facial wrinkles and enhance lips by restoring volume and fullness. Do not have Dermal Filler injections in an area where there is a non resorbable implant or if you have irritated or infected skin, allergy to hyaluronic acid or other severe allergies, autoimmune disorders or hypersensitivity to local anesthetic or porphyria. Caution if you have a bleeding disorder, if you take medicines that prolong bleeding time, have had poor results with previous similar injections, have angina combined with rheumatism or a tendency to large scar formation. Dermal Filler treatments may result in some redness, swelling, pain or tenderness, itching and/or bruising which may last a few days. Inflammatory reactions can last up to two weeks in rare cases. See your healthcare professional if any side effects concern you. Exposure to excessive sunlight or extreme cold should be avoided until redness or swelling has resolved. Dermal Fillers are not recommended for people taking blood thinning medicines and they have not been tested.
