Can I wear fake tan after IPL?

I would suspend using fake tan while on IPL treatment, that includes at least a week before and after you start and finish your IPL treatment.

Yes, however you need to wait for at least a week post treatment. Once the skin has healed and the darkened pigment has come off you can apply a tanner. If you plan on having multiple treatments 3-4 weeks apart you must wait until you are done with your series to apply a fake tan or get a real tan.
