Are you doing the treatments in the same area or different ones? There should be no issue if you're treating different areas, however for the same area I would be cautious to reduce the device setting to prevent excess side effects like redness. If your doctor scheduled your Fraxel for a week after IPL I would think he approves of this procedure- if it was your initiative however I would consult a specialist prior to treatment to avoid unnecessary side effects and prolonged downtime.
IPL can easily be combined with Fraxel- most specialist have been doing this for years- called pulse-fraxel in my practice. This saves you downtime, speeds recovery and gives you better results. Most patients only require one, at the most 2 sessions. So many advantages of combination therapies. Dr Davin Lim. Brisbane. Australia.
