You must understand the logic behind it.
For most of us, peeling lips is due to internal deficiency and also toxicity due to leaky gut. Our lack of good bacteria (caused by taking repeated Antibiotics for me) made it difficult for us to assimilate nutrients, and in the long run, this will reflect as peeling lips.
Cure you gut through natural detoxification, and also taking a good probiotics.
