Facial, neck and chest treatments are usually repeated at 4-week intervals. A series of 4-5 IPL treatment sessions for each area is recommended for optimal results, but this varies by patient. When you come in for a consultation, the doctor can give you a better estimate for how many treatments you will need to accomplish your goal. The sessions are usually reduced to 3 with Levulan®. Once your Los Angeles photo facial treatment sessions are completed, you may need to return for an IPL treatment once a year to maintain this result.
