Accutane is mainly vitamin A! People who are trying to get the same effects as Accutane from Vitamin A take doses from 25000-100000 IUs, I would not recommend going past 16000 UIs without consulting a doctor! Remember to always talk to your doctor before taking any vitamins, I'm not a doctor and he will have more information for you! ALSO WEAR SUNSCREEN AND TONS OF LOTIONS! it will dry your skin and make it easier for you to sunburn! Olay Total Effects Nourishing Cream (, Target) Orign Vitamin A 8000 IU (Target)
