Several scales exist to grade the severity of acne vulgaris, but no single technique has been universally accepted as the diagnostic standard.[68][69] Cook's acne grading scale uses photographs to grade severity from 0 to 8 (0 being the least severe and 8 being the most severe). This scale was the first to use a standardized photographic protocol to assess acne severity; since its creation in 1979, the scale has undergone several revisions.[69] The Leeds acne grading technique counts acne lesions on the face, back, and chest and categorizes them as inflammatory or non-inflammatory. Leeds scores range from 0 (least severe) to 10 (most severe) though modified scales have a maximum score of 12.[69][70] The Pillsbury acne grading scale simply classifies the severity of the acne from grade 1 (least severe) to grade 4 (most severe).[68][71]
The costs and social impact of acne are substantial. In the United States, acne vulgaris is responsible for more than 5 million doctor visits and costs over US$2.5 billion each year in direct costs.[13] Similarly, acne vulgaris is responsible for 3.5 million doctor visits each year in the United Kingdom.[19] Sales for the top ten leading acne treatment brands in the US in 2015, have been reported as amounting to $352 million.[175]
Another once-daily gel your dermatologist might prescribe for acne is Aczone 7.5 percent. The active ingredient, dapsone, is both antimicrobial and anti-inflammatory, and it’s proven to help with blackheads, whiteheads, and deeper painful pimples. Oftentimes, Aczone is used alongside other acne treatments. And like many of those other remedies, Aczone can cause skin to dry out.
Tretinoin: As we said above, tretinoin (common brand name: Retin-A) is a synthetic retinoid, but it is stronger than some of the other options, and its cousin, isotretinoin, is even stronger. Isotretinoin, better known as Accutane, is an oral synthetic retinoid typically only prescribed for very severe cases of cystic acne because it can cause intense side effects and is a powerful teratogen, meaning it causes birth defects. However, after taking isotretinoin for several months, many people never need to do any serious acne treatment again, so for some, it is well worth the side effects.

Azelaic acid has been shown to be effective for mild to moderate acne when applied topically at a 20% concentration.[66][129] Treatment twice daily for six months is necessary, and is as effective as topical benzoyl peroxide 5%, isotretinoin 0.05%, and erythromycin 2%.[130] Azelaic acid is thought to be an effective acne treatment due to its ability to reduce skin cell accumulation in the follicle, and its antibacterial and anti-inflammatory properties.[66] It has a slight skin-lightening effect due to its ability to inhibit melanin synthesis, and is therefore useful in treating of individuals with acne who are also affected by postinflammatory hyperpigmentation.[1] Azelaic acid may cause skin irritation but is otherwise very safe.[131] It is less effective and more expensive than retinoids.[1]
Scars (permanent): People who get acne cysts and nodules often see scars when the acne clears. You can prevent these scars. Be sure to see a dermatologist for treatment if you get acne early — between 8 and 12 years old. If someone in your family had acne cysts and nodules, you also should see a dermatologist if you get acne. Treating acne before cysts and nodules appear can prevent scars.
