Been getting IPL 3x year for the last 6 years for Rosacia. It has worked well to keep the flareups and redness to a minimum. However, this past summer I had an unusually painful IPL, the doctor turned the setting way up and he told me it would help regenerate collagen better. It left me swollen and bruised for a couple days. A month or so later I noticed the skin around the temples had changed to a soft mushy texture with bumps (It used to be smooth.) Also fine lines on my face in odd places.
