If you've wondered how to know what type of acne you have, you've come to the right place. In most cases, acne vulgaris is caused by clogged pores, which can happen for a variety of different reasons (excess oil, dead skin cells, bacteria, hormones, and more).
It can be hard to differentiate between each type of acne lesion, so we’re breaking down how to determine what type of acne you have. From blackheads to inflammatory acne, here are the different types of acne and how to treat them.
What are the different types of acne?
There are six main types of acne: whiteheads, blackheads, papules, pustules, nodules, and cysts. Whiteheads and blackheads and non-inflammatory clogged pores, papules and pustules are inflammatory acne, and nodules and cysts are the most severe acne. Many people experience several kinds of acne, so here's how to tell the difference between them:
Whitehead
Whiteheads, also known as closed comedones, are clogged pores that appear as small skin-colored, firm bumps on the skin. These tend to form when excess oil/sebum and dead skin cells clog your sebaceous gland.
Whiteheads are a type of non inflammatory acne that is best treated with exfoliating acids like salicylic acid, benzoyl peroxide, or a topical retinoid like tretinoin. We know these can be tempting to pop, but popping pimples can actually worsen your breakouts. Try putting a hydrocolloid patch on to provide a protective barrier!
Blackhead
Blackheads, also known as open comedones, are clogged pores that are small, firm bumps that appear dark or black on the surface of the skin. These clogged pores turn dark or black because the excess oil and dead skin cells oxidize when exposed to oxygen.
While some people believe blackheads are common on the nose, normal pores on the T-zone (AKA sebaceous filaments) can also look black because of oxidized sebum. We know it can be frustrating, but these structures are an important part of normal skin! Pore strips were previously a common treatment for stubborn blackheads, but these can be very harsh on the skin. Salicylic acid, benzoyl peroxide, and retinoids are great alternative treatments to help treat and prevent blackheads.
Papule
A papule is a pimple that appears as a small red bump on the skin. These form when a clogged pore bursts and becomes inflamed. A bacteria called c.acnes also plays a role in stimulating inflammation. This form of acne is typically red and inflamed but does not contain pus.
Inflammatory lesions like papules are most commonly treated with topical or oral antibiotics, benzoyl peroxide, retinoids, and potentially spironolactone.
Pustule
Like papules, a pustule forms when a clogged pore bursts and becomes inflamed and filled with pus. This type of pimple appears as a red bump on the skin with a white “head”.
Pustules are best treated with topical or oral antibiotics, benzoyl peroxide, and retinoids to help calm inflammation in the skin. Picking or popping pustules can lead to increased breakouts and can easily cause a scar - so try to resist the urge to pop!
Nodule
Nodules appear on the skin as larger red skin bumps. This type of inflamed pimple tends to be very painful and form deep within the skin. Many dermatologists prescribe oral antibiotics for short periods to help calm down inflammation in the skin and jump start your treatment.
Topical treatments like retinoids are typically recommended alongside oral medications to keep acne under control long term. Oral spironolactone could also be a good long-term option for women with more severe acne or hormonal acne.
Cyst
Cysts are the most severe acne type. Cystic acne appears on the skin as large, red, and inflamed pimples greater than 1 cm in diameter that are deep-seated and filled with pus. A cystic pimple tends to be very painful and is the most difficult to treat.
Cystic acne is best treated under the care of a dermatologist. They will be able to create the best treatment plan to help calm inflammation and treat severe acne over time. Usually, oral and topical treatments are both recommended to help treat cysts.
