Hey Daniel, do you think if for some reason you had to stop or reduce your exposure to the sun, that your EC would come back, or your lips regress a little? You said you get sometimes 1-2 hrs or all day exposure, which is quite alot. I live in AZ, so getting some sunlight isn't a problem. I've just been trying to avoid it right now because I'm using topical vitamin D, and too much exposure to sunlight can decrease or inhibit results. Anyways, just thinking out loud! I'm one of your friends on FB and am glad to see you enjoying life!
