My lips have a horrible darker patch!
My lips have a darker patch on the middle of them, It looks really disgusting, I noticed the problem about a year ago. It could be related to my new toothpaste I use which contains Baking Soda, I heard that may damage lips. Should I visit a dermatologist or buy new lip balm? I've tried many nivea lip balms but none have proven successful.
Thankyou!
