Figure 3. Acne Assessment Examples Using the Proposed Acne Scale.

A, Mild indicates approximately 5 (some) comedones with the presence of postinflammatory color changes and some ice-pick scars (mild/moderate). Lesion count fixes row 2 (R2) in Figure 2, whereas background activity moves the rating to column 3 in Figure 2. B, Mild to moderate indicates approximately 8 comedones, 1 to 2 pustules/papules, and postinflammatory color (in particular, color changes due to treatment) with mild/moderate inflammation and scars (column 3 in Figure 2). This acne was more severe in the past, but because it is at the end of treatment, it now falls in the category of topical disease with consideration (in this case, continue) of oral therapy. C, Moderate indicates increased papules (4-5), more than 12 comedones, postinflammatory color changes, and mild/moderate inflammation (column 3 in Figure 2). D, Moderate to less severe indicates more than 8 papules, postinflammatory color changes, and mild/moderate inflammation and scars (column 3 in Figure 2). E, Severe indicates more than 8 papules and 1 nodule and severe inflammation and scarring (column 5 in Figure 2).
