Types and uses Hyaluronic acid is commonly used, while other products stimulate collagen or provide longer-lasting volume. Product choice depends on the area, tissue depth, desired result and patient factors.
Results Many results are visible immediately, although swelling may temporarily alter appearance. Duration ranges from months to longer depending on the product and area.
Common and serious risks Bruising, swelling, tenderness, lumps and asymmetry can occur. Infection and delayed inflammatory reactions are less common. Accidental injection into a blood vessel is rare but can cause skin injury, vision loss or stroke and requires immediate treatment.
Safe treatment Fillers should be injected only by a qualified medical professional using approved products. Severe pain, pale or mottled skin, visual symptoms, weakness or intense headache after injection require emergency assessment.
