Quick Answer: What are clogged pores?
Clogged pores are skin openings blocked by dead skin cells, oil, dirt and bacteria, most often on the face, leading to whiteheads, blackheads, pimples and deeper cysts [1]. They are very common, especially in adolescence and young adulthood [1] [2]. A provider diagnoses them by examining the skin [1]. Gentle daily cleansing, non-comedogenic products and retinol or salicylic acid usually clear them [1].
Key takeaways
Dead skin cells, oil, dirt and bacteria get trapped in skin openings and block the pore [1].
Clogged pores are the leading cause of acne, which affects up to 50 million Americans a year [1] [2].
They show up as whiteheads, blackheads, pimples, pustules, nodules and cysts [1].
Oily skin raises the risk [1]. They are common in adolescents and young adults, but anyone can get them [1].
A gentle routine fixes most cases: non-comedogenic products, twice-daily washing with warm water, and retinol or salicylic acid [1].
Prevention is simple: clean hands, no facial oils, gentle exfoliation, and no picking or popping [1].
What the research says
Topical retinoids are among the most strongly recommended acne treatments. The American Academy of Dermatology's 2024 guideline, built on a systematic review, makes 18 evidence-based recommendations and 5 good practice statements. It strongly recommends benzoyl peroxide and topical retinoids, gives conditional recommendations for salicylic acid and azelaic acid, and lists combining topical treatments with different mechanisms as good practice. The guideline covers acne in general, not clogged pores alone (Reynolds et al., J Am Acad Dermatol, 2024 [3]).
Salicylic acid worked about as well as tretinoin in the trials that compared them. A Cochrane review of 49 trials with 3,880 participants found there may be little or no difference in participants' own ratings of improvement between salicylic acid and tretinoin (RR 1.00, 95% CI 0.92 to 1.09). Side effects of these topical treatments were mild and temporary. Evidence for most of the products was low or very low quality (Liu et al., J Evid Based Med, 2020 [4]).
Combination products beat single ingredients for mild to moderate acne. A network meta-analysis of 179 randomized trials (about 35,000 observations) found that a retinoid combined with benzoyl peroxide cut total lesion counts by 26.16% more than placebo (95% credible interval 16.75 to 35.36%). Chemical peels such as salicylic or mandelic acid showed a larger estimated effect (39.70%, 95% credible interval 12.54 to 66.78%) but with high uncertainty. Benzoyl peroxide and topical retinoids were less well tolerated than placebo (Mavranezouli et al., Br J Dermatol, 2022 [5]).
What Are Clogged Pores?
Clogged pores develop when dead skin cells, oil or dirt get trapped in your pores [1]. Pores are tiny openings in your skin that release oil and sweat from your glands [1]. Clogged pores contain a buildup of dead skin cells, oil, dirt and bacteria, and clogged pores can lead to acne [1].
Clogged pores are common on people's faces, but they can occur anywhere on your body, including your scalp, neck, back, shoulders and chest [1]. Clogs on the back are covered in our guide to back acne.
Clogged Pores vs. Enlarged Pores
Clogged pores and enlarged pores are not the same thing, but they are often related. Clogged pores can be the result of your glands producing too much oil, and more oil on your skin increases the risk of clogged pores. Lots of other things can lead to enlarged pores, however, including age, skin products, hair follicles and sun damage, so enlarged pores do not always lead to clogged pores [1].
Feature | Clogged pores vs. enlarged pores |
What happens | Clogged pores: debris (dead skin, oil, dirt, bacteria) gets trapped in the pore. Enlarged pores: the pore opening widens. |
Main driver | Clogged pores: glands producing too much oil. Enlarged pores: age, skin products, hair follicles, sun damage. |
Lead to acne? | Clogged pores: yes, they are the leading cause of acne. Enlarged pores: not always. |
Who Gets Clogged Pores?
Similar to acne, clogged pores tend to be more common in adolescents and young adults, because during puberty hormones stimulate the glands that produce oil [1]. But anyone of any age or sex can get clogged pores [1].
Having a family history of acne or clogged pores can also increase your risk, since sometimes you inherit genes from your parents that make you more likely to have very oily or dry skin [1].
How Common Are Clogged Pores?
Clogged pores are very common. Acne affects up to 50 million Americans each year, according to the American Academy of Dermatology [2], and clogged pores are the leading cause of acne [1].
Clogged Pores Symptoms and Signs
Most people notice clogged pores only when they lead to one of the following skin concerns. The mildest form, made of whiteheads and blackheads without redness, is called comedonal acne.
Blemish | What it is |
Whiteheads | A clog in the opening of a pore causes a raised white or flesh-colored bump on the skin; also called a closed comedo (closed pore) or a zit [1] |
Blackheads | A clog that widens the opening of the pore. It is not black because of dirt; it is the chemical reaction of the pore's content mixing with oxygen [1]. Also called an open comedo (open pore). A very large blackhead is a dilated pore of Winer, an opening in your skin filled with a blue or black substance |
Pimples and pustules | A lot of dirt and oil inside a pore leads to redness, swelling and irritation. Whiteheads and blackheads are types of pimples. Pimples are also called papules; if they contain pus, they are pustules [1] |
Nodules and cysts | A very clogged pore causes swelling, pain and irritation deep in the skin. If a nodule contains pus, it is called a cyst. Cystic acne can lead to acne scars [1] |
What Causes Clogged Pores?
A buildup of dead skin cells, oil or dirt can clog pores [1].
Some things do not directly cause clogged pores, but can make them worse [1]:
Aggravating factor | How it makes clogs worse |
Certain foods | May aggravate clogged pores |
Rubbing gear | Clothing, backpacks, helmets or other garments or equipment that rub against your skin |
Humidity | Humid conditions can worsen clogs |
Picking | Picking at pimples makes matters worse |
Stress and anxiety | Can aggravate clogged pores |
Over-scrubbing | Washing or scrubbing your skin too hard |
How Are Clogged Pores Diagnosed?
There is not a test for clogged pores [1]. Your healthcare provider examines your skin and reviews your medical history [1]. They may also ask you about your current medications, your family medical history, and your skin care routine.
Clogged Pores Treatment Options
Most people can manage mild to moderate clogged pores with a few routine adjustments.
Treatment step | How to do it |
Non-comedogenic products | Choose cleansers, cosmetics and moisturizers labeled "non-comedogenic" or "oil-free." The term means a product is formulated not to clog pores [1] |
Cleanse and moisturize regularly | Gently wash your face twice each day with a non-comedogenic cleanser and warm (not hot) water; use an oil-free moisturizer after cleansing to avoid dry skin [1] |
Retinol or salicylic acid |
Outlook / Prognosis
Clogged pores are not usually cause for alarm. They usually clear up with the right skin treatments [1]. If you are concerned about pimples or other blemishes caused by clogged pores, talk to your healthcare provider.
Prevention
You can help prevent clogged pores by sticking to a skin care routine that is right for your age, skin type and skin concerns. A dermatologist (a medical doctor who specializes in skin conditions) can recommend the right products and treatments [1].
Other ways to prevent clogged pores include avoiding touching your skin with unwashed hands, not using oil on your face (such as coconut oil, olive oil or jojoba oil), exfoliating your skin with gentle scrubbing or periodic chemical peels, keeping your skin clean and moisturized, and never picking at or popping pimples [1].
Prevention habit | Why it helps |
Matched skincare routine | A routine right for your age, skin type and concerns; a dermatologist can advise |
Clean hands on face | Avoid touching skin with unwashed hands |
No facial oils | Skip coconut, olive and jojoba oils on your face |
Gentle exfoliation | Gentle scrubbing or periodic chemical peels remove buildup |
Clean and moisturized skin | Keeping skin clean and moisturized |
No picking or popping | Never pick at or pop pimples |
Living With Clogged Pores
Contact your doctor if you have acne that is painful, inflamed, infected or filled with pus [1]. You should also reach out to your provider if you notice any abnormal skin growths or lesions [1].
Clogged pores are a common skin condition caused by a buildup of dead skin cells, oil or dirt. Clogged pores can lead to acne, but they are fairly easy to treat. Regular cleansing with non-comedogenic skin care products usually resolves clogged pores, and some people need special skin ointments that contain retinol or salicylic acid.
Conclusion
Clogged pores are one of the most common skin concerns, and they are the leading cause of acne, a condition that touches up to 50 million Americans every year. They form when dead skin cells, oil, dirt and bacteria get trapped in the tiny openings that release your skin's oil and sweat, and they most often show up as whiteheads, blackheads, pimples or, deeper down, nodules and cysts. The causes are everyday ones: dry or extra-productive skin, pore-clogging cosmetics, oil-changing medications, and oily skin driven by age, hormones or genes. The good news is that gentle care usually wins: non-comedogenic products, twice-daily washing with warm water, and, where needed, retinol or salicylic acid. With steady prevention habits and a routine suited to your skin, most clogged pores clear without drama.
