Question: What are the main types of acne?
Answer: As opposed to categorizing acne by the lesions involved, acne is actually classified into four grades:
- Grade 1 (mild acne): microcomedones, or blocked pores, along with open and closed comedones, which are blackheads.
- Grade 2 (mild/inflammatory): microcomedones, as well as occasional papules, which are pimples.
- Grade 3 (acne vulgaris): includes congestion, with papules and pustules.
- Grade 4 (cystic acne): can include all of the above with nodules and cysts.
Grade three and four are the most serious and may require medical intervention, whereas everyone could be said to suffer from grade one and occasionally grade two.
