Hi, my mom has been staying with my brother for the past 5 years and he sent her to me last month. She has arthritis problem. She has dark dots on her hands and has sun spots too. I have heard that Broad Band Light treatment which is used to treat such skin conditions associated with aging and planning to take her to The Centre for Dermatology in Richmond Hill. Will it create any side effects as she has arthritis problem? Have any of you tried this? Any suggestions would be appreciated.
