Tretinoin acetate belongs to the glucocorticoid class of drugs and can be used for the treatment of the face if the condition requires symptomatic use, but it is necessary to master the course of medication. Long-term use of this drug may cause skin atrophy, capillary dilation, pigmentation and secondary infection, so it should not be used on a large scale or for a long time. If your symptoms are not relieved after 1 week of use, consult your doctor. This drug may occasionally cause allergic reactions. If there is a burning sensation, redness or swelling at the site of application, the drug should be stopped and the area should be washed off, consult your doctor if necessary. Avoid contact with eyes and other mucous membranes, such as the mouth and nose, when applying, and do not use on broken skin. Tretinoin acetate is indicated for allergic dermatitis, eczema, neurodermatitis, seborrheic dermatitis and pruritus, and rational use of the drug is the key.
