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 other downside to Proactiv+ is that the bottles are small — like, half the size of Paula’s Choice small. Combine that with its recommended two or three-times daily application, and you’re going to be going through a lot of kits, which ultimately means spending more money on your treatment. If Proactiv is the only thing that works for you, it may very well be worth the investment, but we recommend starting with Paula’s Choice to see if you can get the same results at a cheaper price.
Depression and acne can go hand in hand, and one often leads to the other. In cases where acne occurs first, it’s not uncommon for people to want to withdraw from the world. Whether it’s internal embarrassment or external bullying, acne can lead to an extreme loss of confidence and low self-esteem. How to get rid of a pimple may seem impossible, and the emotional toll of acne can impact anyone at any age, and as depression worsens so too does the acne. In some cases, an individual without skincare issues who becomes depressed could incidentally develop acne. Depression can lead to poor hygiene habits, and failing to wash your face contributes to buildups within clogged pores. Depressed people may also experience poor sleep, which can lead to acne by inhibiting your body’s natural, night-time keratinization process.

Blackheads are a mild form of acne that appear as unsightly, open pores that look darker than the skin surrounding them. They get their dark appearance from a skin pigment called melanin, which oxidizes and turns black when it's exposed to the air. Blackheads aren't caused by dirt, but by sebum (oil) and dead skin cells blocking the pore. If the pore remains open, it becomes a blackhead; if it's completely blocked and closed, it turns into a whitehead.

Shah often recommends over-the-counter retinols or prescription retinoids to her acne-prone patients. “I find that compared to other treatments they are beneficial for not just treating acne but also preventing new acne from forming as they help prevent that initial stage of the follicle getting clogged,” she says. “They can also help with some of the post acne [problems] such as hyperpigmentation.” But keep in mind if you have sensitive skin (or eczema or rosacea), a prescription retinoid might be too strong an option. However, your dermatologist can recommend an over-the-counter retinol with a low concentration (0.1 to 0.25 percent), which might be better tolerated. Retinol also isn’t a quick fix. It takes time to see results, and it’s something you’ll have to keep using to maintain its benefits. Shah also mentions that retinol plays well with other acne treatments on the list. "Retinol can be combined with other over-the-counter or prescription medications such as benzoyl peroxide, topical antibiotics, and oral medications. The right combination depends on the severity of the acne and your skin type."
Retinoids and retinoid-like drugs. These come as creams, gels and lotions. Retinoid drugs are derived from vitamin A and include tretinoin (Avita, Retin-A, others), adapalene (Differin) and tazarotene (Tazorac, Avage). You apply this medication in the evening, beginning with three times a week, then daily as your skin becomes used to it. It works by preventing plugging of the hair follicles.
