REVIEW Isotretinoin noticeably reduces the production of sebum and shrinks the sebaceous glands. It stabilises keratinization and prevents comedones from forming. It also reduces inflammation in moderate-severe inflammatory acne. The exact mechanism of action is unknown, however it is known that it alters DNA transcription.
