I’ve been routinely using Platinum LED full body lights treatments for perhaps a year. I had a scaly thick & very itchy patch on my ankle which had all the characteristics of psoriasis. It disappeared after several treatments. My pustular rosacea has improved greatly as has my complexion in general. I use the lights for 5 minutes before & after workouts. I believe this increases the effectiveness of results. The lights have been effective in diminishing SAD symptoms. In short I am extremely pleased with my investment & I am continuing treatments several times a week.
