Fibroblast Skin Tightening treatment takes a very short time, with stress on the aftercare. If the patient neglects the instructions for aftercare, the treated area may suffer from: inflammation, hyper-pigmentation, scarring and lack of maximum effect. FST treatment is an exceptionally safe procedure with virtually no side effects or they occur very rarely. Possible side effects are inflammation, scarring or minor change in skin pigmentation, which is very rare. It is highly important for each patient to follow the instructions for aftercare closely. Micro-scabs which occur after the treatment are part of the treatment and will fall off after 4-5 days. Minor swelling after treating the area around the eyes is normal and will disappear after 3-5 days, depending on the patient’s sensitivity. Pain- Most people feel some heat-related discomfort during the treatment. This discomfort is usually temporary during the procedure and localized within the treatment area. Redness and Swelling- FST treatments will cause varying degrees of redness and swelling in the treatment area. These common side effects usually last from several days to a few weeks. Prolonged redness, although rare, has been previously documented to last several months Itching- This can occur as part of the normal wound healing process or may occur as part of infection, poor wound healing or contact dermatitis.
