The wrinkles on the forehead can be straightened. The longer and deeper the frontal lobes are, the longer will be the process to straighten the wrinkles. Therefore prevention is easier. The frontal lobes will be filled in lines with hyaluronic acid.
Injection of hyaluronic acid always stimulates re-emergence of collagen fibers, so that a unique treatment can achieve a much longer success.
Injections can cause extensive hematoma at the puncture. The dimension of the hematoma depends on treatment and the patient’s coagulation parameter. Therefore at least 2 days before such a treatment, blood-thinner (e.g. Aspirin) should not be taken. Furthermore in the first 4 days unevennesse’s and swellings can occur, which will disappear with massaging and spreading.
