Hello and welcome to HCM.
Thank you for your query.
Peeling and dryness of the areola
region also occurs due to climate changes and also hydration level of the body at times. Unless you have any other symptoms, this should not be worrisome.
Please note, that dryness of the skin around the nipple and the areolas can leave open cracked skin. If left untreated or properly cared for, this can lead to an infection, as infection-causing organisms can enter through these cracks in the skin and cause infections.
The use of petroleum jelly should help in keeping the skin from cracking. If this persists for a long duration, visiting a doctor would be beneficial.
I hope I have succeeded in answering your questions, you could write back to me anytime for further clarifications.
