Using moisturizer is not a medical treatment.
Before also I used to use moisturizers but when my lips used to touch water they would peel like thick sheets.
Now now my lips are 100% normal. It might take some more time to completely giveup moisturizers. Now I am on one of the coldest regions on earth, so using moisturizer is a norm!
I would attribute my cure to:
50%----- brushing and mouth wash
I absolutely avoided all kinds of sugars for over 1 year now. Took good qualty probiotics.
