Anaesthetic is applied to the area via creams or injections before the procedure begins. After a certain period of time has passed, the skin is cleaned with antiseptic and then the filler injections are used. More than one type of filler can be used on the same person depending on the depth of the lines and creases. For deeper ones, more successful results are obtained when the procedure is repeated 3 months later. Strenuous physical activity, massages, and very hot/cold places should be avoided for 3 days after the procedure (until swelling and redness disappear). The following day skin-care products can be used. Side effects such as redness, swelling and bruising may be seen.
