Your skin may become red and swollen. This may be a normal reaction and can last from an hour to several hours to a few days following treatment. Application of cold compress or ice for the first 24 hours will help minimize swelling. Freckles and sunspots may turn darker initially and then flake off eventually. This is normal and expected. Light scabbing or crusting may occur and is normal. Apply a topical antibiotic ointment as directed. If your skin blisters or becomes painful, please call the Advanced Cosmetic & Plastic Surgery office: (203) 438-5080.
