It can be due to vit B deficiency. Take some vitamin B complex for some days and see if your symptoms improve.
Secondly, it can be due to atopic dermatitis or eczema. Drugs which you are using can be responsible for this. Treatment is by topical steroids or oral therapy of corticosteroids in severe cases. Topical creams like tacrolimus ointment (Protopic) and pimecrolimus cream (Elidel) are also useful.
If the symptoms persist then a dermatologist’s consultation is the best.
Hope it helps. Take care and please do keep me posted in case you have any additional queries. Kind regards.
Hi there, I seem to have a very similar case to dry lips. Have mines for 3-4 yrs now but seems to be getting a bit worst. I've tried EVERYTHING. Have very very dry lips top and bottom, no itching, and at times i get rashes after using various products. Lips get extremely white dry and looks horrible, very embarrassing. Went to various doctors and took treatments for possible fungal infection, and took also hydrocortisone ointment. Only product that helps a bit is 100% petroleum jelly as recommended by my dermatologist. Can you please tell me what I can do to evade this problem. Any assistance on what this could be and what I can try will be very helpful. Much much thanks.
