I just got back from the beach and I have a tan! I have red hair and freckles, so normally I burn. I take 8 drops of Lugols per day and while at the beach, I added a few drops to VCO instead of sunscreen. It worked!
I am not crazy - I know that I will probably never be able to stay in the sun all day, especially during peak hours, but I have a nice base tan now and I feel great!
