When should I consider isotretinoin (Roaccutane) for my acne?

Isotretinoin (roaccutane) is a powerful treatment for acne, however it does have the potential for side effects (see our post on isotretinoin side effects). For this reason, in most countries, it is only prescribed by a dermatologist. Isotretinoin is usually considered for moderate or severe acne when previous systemic (tablet) treatments have not proven effective or where acne has recurred rapidly following another treatment such as antibiotics or the oral contraceptive pill. In some cases, where there is severe acne resulting in extensive scarring there is an argument for starting isotretinoin at an earlier stage.

I am a London-based Consultant Dermatologist and Dermatological Surgeon. I am highly experienced in skin cancer diagnosis, Mohs micrographic surgery, acne, rosacea, acne scarring and laser treatments. I studied at the Universities of Cambridge and Oxford, and completed my dermatology training and Mohs fellowship at the prestigious St John’s Institute of Dermatology. I graduated from medical school in 2003 and have worked exclusively in Dermatology since 2012.

I lead a research team at King’s College London investigating the molecular biology of skin cancer. In recent years I have been involved in Media Appearances, including the Channel 5 series 'Skin A&E', where I perform skin surgeries and treat various skin conditions. Filming for the next series has recently completed and the series will be released later in 2025.
