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.

How can I help

I see patients in person in central London. An in person consultation allows me to examine the skin directly including features that are difficult to capture in a photograph such as 3-dimensional changes and textural change. This is the better option where the diagnosis is uncertain, where previous treatment has not been effective, or where a procedure is being considered. For more straightforward conditions such as acne and rosacea a remote consultation with clear photographs can be a good option.
