Hello,
It looks like contact dermatitis. The treatments
of this condition are application
of topical corticosteroids (betamethasone, clobatesol, flucinolone) which will reduce the inflammatory process. Topical immunomodulators like pimecrolimus and tacrolimus can be used in severe conditions.
I hope it helps. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided.
