Side effects of an IPL Photofacial may include temporary redness, swelling and mild discomfort during or immediately after the treatment. In some cases, patients may experience a sunburn-like feeling for up to 24 hours following the procedure. Additionally, darkening or lightening of the pigmented area can occur temporarily but should fade as your skin heals, usually within a few days. Lastly, some patients may experience mild blistering or scabbing which will heal in time. It is important to follow the aftercare instructions provided by your doctor to reduce any side effects of the procedure.
