Can an LED device, such as the LightStim for wrinkles, cause hyper pigmentation?
If so, with continued use, will the hyper pigmentation eventually get better or worse? I have light freckles and am prone to melasma. My melasma is worse in the summer and gets a little better in the fall. But after using the lightstim for a few weeks, my face seems more blotchy. I wasn't sure if it was my imagination, but found other comments online that some people thought LED lights caused hyper pigmentation for them too. Should I discontinue use, or is this a stage that I will get past?
