Vitamin A is an essential substance to maintain the normal function of human epithelial tissue. When the human body lacks it, it will cause problems such as dry skin, rounded hair and keratosis of conjunctiva. Isotretinoin is a derivative of vitamin A. Isotretinoin should be the first choice for patients with severe acne who are generally ineffective in treatment, including patients who are ineffective in full and full course of systemic antibiotic treatment, or patients with acne vulgaris, fulminant acne and facial pyoderma with severe nodules or cysts. Oral prednisone is often used at the initial stage of treatment, but it can be gradually stopped within 3-4 weeks.

The recommended dose of isotretinoin is 0.5-2 mg per kg body weight per day for 16-20 weeks. It is also effective for severe purulent sweat glands, rosacea, gram-negative acne, and keratinization of hair follicles. This is ineffective in general treatment. In addition, isotretinoin can stimulate the production of collagen, which is a substance that makes human skin firm and young. The more collagen fibers there are in the skin, the less wrinkles there will be. The medicine can also stimulate the growth of new blood vessels, make the skin look rosy and healthy, make dead cells fall off and grow fresh skin, so it is also made into glue, milk and cream to remove wrinkles abroad.

However, taking isotretinoin should not be used with vitamin A or tetracycline. The most serious side effect of isotretinoin is teratogenesis. After taking this medicine, 1/3 patients had spontaneous abortion, 1/3 needed induced labor, and 20% of the fetuses in 1/3 had severe congenital malformation. Therefore, when women in reproductive period need isotretinoin treatment, pregnancy should be ruled out first. Other side effects of isotretinoin include dry mouth, cheilitis, dry mouth, dry skin and desquamation. So please use this medicine under the guidance of a doctor and pay attention to sun protection.
