I received 1 IPL treatment for dark spots and did not wear a hat after the 6th day of having the treatment. I also wore a sunblock that was SPF 30 instead of SPF 40 for five days. I have several spots now, and there is more hyperpigmentation than there used to be. I would like to get IPL again to get rid of these spots, but I have some questions. With each subsequent IPL treatment does your skin usually get more hyperpigmenation, or does it repair the skin permanently as long as you stay out of the sun?
