The condition can be tinea corporis
, xerotic eczema ,contact dermatitis
, Polymorphic light eruption etc.You should also maintain photoprotection by using sunscreen regularly.
You need to apply liberal moisturizer daily over the area.A mild steroid like hydrocortisone
for few days can be helpful.
A skin biopsy may be required for diagnosis.
Please visit a qualified dermatologist
for proper diagnosis and treatment.
Hope this helps.
