This is a psoriasis patient.And whatever you have experienced that, the same was happened to my wife also.
Hello,
It looks like irritant contact dermatitis to the lotion. Wear gloves while applying this lotion. 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.
