A dermatologist made me buy it. Serious problem with allergy, urticaria, itching, and wounds on the lower limbs. Apply after showering to wet feet. It does a spectacular job. If there are wounds, it stings a little at first. Although it is white, it does not leave a white residue. Beyond that, perhaps for some people it is a negative that it is hardly absorbed at all. The feeling of the application remains for many hours, as if there is a protective film. But probably for this reason, it has completely eliminated my symptoms. I would easily buy it again because corticosteroid creams (like Butavate/Movithiol) should be avoided to prevent addiction and/or skin atrophy.
