Vitamin E can be applied directly to the face. The diseases that are generally treated are seborrheic dermatitis, allergic dermatitis, psoriasis, and hormone-dependent dermatitis. For seborrheic dermatitis, allergic dermatitis, and hormone dependent dermatitis, in addition to applying vitamin E, you can take oral antihistamines. For example, levocetirizine hydrochloride capsules, olopatadine hydrochloride tablets, loratadine citrate capsules, desloratadine syrup, loratadine syrup, and also topical zinc oxide borate ointment can be used for treatment. For psoriasis, oral anti-silver tablets, anti-silver pellets, and danqing capsules are needed, and tacrolimus ointment and pimecrolimus cream can be used topically on the face. All of the above treatments require avoidance of spicy and stimulating diets, and avoiding strong and persistent sunlight exposure.
