There is no universal agreed scoring system for acne, but categorising symptoms as mild, moderate and severe can be helpful in the selection of appropriate treatment and monitoring of response:
- Mild acne – predominately open and closed comedones with few inflammatory lesions
- Moderate acne – more widespread with an increased number of inflammatory papules and pustules
- Severe acne – widespread inflammatory papules, pustules and nodules or cysts. Scarring may be present.2
