In some cases, people may develop a nasolabial fold on one side and thus a drooping corner of the mouth. This occurs, for example, in the case of partial fascial paresis, e.g. after a stroke. In this case, it can be advantageous or even sensible to inject the wrinkle on one side only in order to achieve the desired effect on one side only and thus restore symmetry.
Alternatively, the attending physician can apply different amounts on both sides. This example illustrates the extent to which high-quality training is required for specialists in aesthetic medicine. Always choose experts in plastic and aesthetic surgery who have many years of proven professional experience. Only in the hands of experienced doctors can you be absolutely sure that the anatomy of your face is known exactly and that correct action will be taken in the event of unexpected complications.
