The HydraFacial treatment is a safe and comfortable procedure with few potential side effects. The patient might experience slight discomfort, tightness and/or redness of the skin for an hour or two following the procedure, but this is not common. Very seldom, redness may linger for a day or so. A cold compress can help to minimize this side effect. Scarring is also possible but very rare. We do not at all anticipate this will happen during your treatment.
