I will be undergoing 6 LED facials. I understand the waiting time between sessions should be about 2 weeks. I would also like to have IPL treatments to treat redness / sun damage. The waiting time would be 4 weeks between treatments. Can I have an LED in the middle of the waiting time between IPL treatments? i.e. have IPL treatment, then LED to weeks later, IPL treatment 2 weeks after that, LED two weeks after that, and so on.
