That's great! It's likely due to lower levels of insulin:
I have had dirty-looking knees for what seems like years. (I forget the scientific name- but it's abbreviated AN)
Dermatologists have Rx'd creams, I checked into lasers, I've scrubbed, applied lemon juice, what have you...they never went away. ugly. ugly. ugly.
I've been gluten-free and dairy-free for the better part of a year. Recently on my way primal (obviously) and !lo and behold! the other day I noticed that they were GONE! I have lily-white, shiney knees for the first time in I dont know when. Thank you new way of eating.
This is such great news! My son and I both have "dirty elbows" and we've tried all the things you mentioned...even resorted to bleach, I'm sad to say. We just got off gluten, but this is a great benefit to look forward to down the line!

Also try rubbing into your skin some extra virgin coconut oil. It's very healing for skin conditions.
Are you tan and have a darker knees and elbows? I think i have the same situation and i desperately want to get rid of it! I've tried various lotions & even lemon. How long did it take for you to remove it?
I have had a similar improvement with the skin on my elbows and neck. The bumps on my arms also disappeared. My skin just looks and feels better in general.
