For years my eyebrows looked like Brooke Shields. Thick and long so I trimmed them. Six years ago I lost the outer half, now that has grown back. Within the last 6 months I've lost the innter bushiness that brought them to close together. It's amazing what age does to hair, but I do believe that the Iodine has reduced the number of hairs on my face. If your getting them on your chin, you might have gotten more by now if you had not been doing the iodine.
