cut the lemon and rub th lemon juice on your elbows and leave for 20 minutes repeat this twice a week and don t forget to apply some lotion or cream after washing it. Ihope it ll help you as acid in lemon juice is good for lightening colour.
I have dry elbows and knees and after spending a fortune on creams like , elizabeth ardan 8 hr cream, I have found that some sudocream really helps to clear up dry skin. It's only about £2 and is so much better than some creams that I have bought that have cost a lot more.
