Hey guys i wanted to know if i really have EC. What is the defference between EC and chapped lips is it the swelling? B/c i do have swelling and chapping for 7 year s now. but all things i put on my lips make the swelling worse but they do kinda stop the chapping on the bottom lip. The biopsy they did 7 years ago did not say anything but they contributed to contact dermititis. The lips do turn white when they hit water but could that happen with regular chapped lips?
