Acne can be broadly classified into the following categories:
Mild: The disease consists of open and closed comedones with some superficial papules and pustules.
Moderate: More frequent deeper papules and pustules with mild scarring.
Severe: Includes all of the above plus nodular abscesses and leads to more extensive scarring.
- Refer to algorithm.
- All topical acne treatments should be applied to the whole area affected throughout the course, even during periods of relative quiescence and ‘drug holidays’ from oral antibiotics.
