There are two main types of dermatoprost on the market: one is dexamethasone acetate and the other is mometasone furoate. Both are glucocorticoid ointments with anti-inflammatory, anti-allergic reactions and anti-itch effects, which can significantly reduce capillary permeability, reduce exudation and infiltration, so it will have a significant effect on allergic dermatitis. However, because it contains hormones, it should not be used topically for a long time and in large quantities. Short-term, reasonable and adequate topical application is possible, but it should be considered according to the specific condition. If used for a long time and in large quantities, there is a risk of skin atrophy and capillary dilation, which can further cause hormone-dependent dermatitis. dermatoprene should be used under the guidance of a professional doctor.
