Why Men Get Acne: 7 Real Causes (and What to Actually Do About It)

Men get acne because testosterone and other male hormones stimulate oil-producing glands in the skin to work overtime — creating the perfect conditions for pores to clog and bacteria to thrive. But hormones are just one piece of the puzzle.

Studies show that approximately 4 in 10 adult men experience acne beyond their teenage years, yet most men never seek help — often dismissing breakouts as something they simply have to live with. They don't.

This guide covers every significant cause of acne in men, how male acne differs from female acne, where it tends to appear, and what treatments actually work. If you want to know what's triggering your specific breakouts, mymirror can surface observations about your specific skin in under 60 seconds.

7 reasons why men get acne

Acne happens when a hair follicle becomes clogged with oil (sebum) and dead skin cells. Bacteria called Cutibacterium acnes (formerly Propionibacterium acnes) colonise the blocked follicle, causing the inflammation that shows up as redness, swelling, and pus. In men, several factors make this process particularly likely to occur.

• 01

  Testosterone and androgens

  The primary driver of male acne is hormonal. Testosterone and related androgens bind to receptors in the sebaceous (oil) glands, directly stimulating them to produce more sebum. Higher androgen levels mean oilier skin, larger pores, and a significantly greater chance of follicle blockages. This is why acne often first appears during puberty — when testosterone surges — and why men are more acne-prone than women throughout their lives. Fluctuations in testosterone, rather than simply high levels, can trigger breakouts even in adult men.

• 02

  Naturally oilier skin

  Men's skin produces approximately 20% more sebum than women's, even when testosterone levels are similar. This is partly due to men having a greater density of sebaceous glands. More oil production creates a more hospitable environment for acne-causing bacteria and increases the rate at which pores become blocked — making routine skincare even more important for men, not less.

• 03

  Diet: high-glycaemic foods, dairy and whey protein

  What you eat has a measurable impact on acne. Foods with a high glycaemic index — white bread, sugary drinks, processed snacks — cause rapid spikes in insulin, which in turn stimulates androgen production and increases sebum output. Dairy products and whey protein supplements (popular among men who exercise) raise insulin-like growth factor 1 (IGF-1), which has a similar effect. Switching to lower-glycaemic foods has been shown in clinical studies to reduce acne severity.

• 04

  Shaving irritation and razor bumps

  Shaving is a uniquely male acne trigger. A dull blade, pressing too hard, or shaving against the grain causes micro-tears in the skin that allow bacteria to enter follicles. For men with curly or coarse hair, shaved hairs can curl back into the skin (ingrown hairs), causing a type of follicle inflammation that looks almost identical to acne — a condition called pseudofolliculitis barbae, or "razor bumps." Using a clean, sharp blade with a non-comedogenic shaving gel, and shaving in the direction of hair growth, significantly reduces this risk.

• 05

  Anabolic steroids and certain medications

  Anabolic steroids used for muscle gain are one of the most potent acne triggers for men. Around one in three men who use anabolic steroids develop acne, and approximately half of those develop severe cystic acne — often on the back and chest as well as the face. This type of acne is particularly resistant to standard treatments. Other medications that can cause or worsen acne include corticosteroids (prednisone), lithium, and some antidepressants.

• 06

  Stress and poor sleep

  Psychological stress triggers the release of cortisol, which in turn stimulates the adrenal glands to produce more androgens — again increasing sebum production. Chronic stress also promotes systemic inflammation, which exacerbates existing acne. Poor sleep disrupts the balance of stress hormones overnight and impairs the skin's natural repair processes. Men in high-pressure jobs or going through major life changes often report worsening breakouts during these periods.

• 07

  Genetics and family history

  If your father or brother had significant acne, you are considerably more likely to experience it yourself. Genetics influence the size and activity of your sebaceous glands, how your immune system responds to C. acnes bacteria, and how your skin sheds dead cells — all of which affect acne risk. While you cannot change your genetic predisposition, knowing it exists means you can take targeted preventive steps earlier.

How men's acne differs from women's

While the underlying biology of acne is similar across sexes, there are important differences in how acne behaves in men — and this matters for treatment.

The key clinical implication is that the hormonal treatments commonly used for women — spironolactone (an androgen blocker) and oestrogen-containing contraceptives — are not appropriate for men. Treatment strategies for men therefore rely more heavily on topical retinoids, antibiotics, and isotretinoin (Accutane) for severe cases. Men's skin is also generally more robust, meaning stronger topical concentrations are typically better tolerated.

Where on the body men get acne

The location of acne often gives useful clues about its cause.

Facial acne

The face — particularly the forehead, nose, and jaw — is the most common site. Jaw and chin acne in men is closely linked to hormonal activity and, in men who grow beards, to bacteria trapped beneath facial hair. Forehead acne can be worsened by hair products that migrate onto the face during the day or night. Using non-comedogenic (non-pore-blocking) skincare and haircare products is essential.

Back acne (bacne)

The back has an exceptionally high concentration of sebaceous glands, making it a common site for acne in men — particularly in those who exercise regularly or sweat heavily. Friction from gym equipment, backpacks, or tight clothing (a phenomenon sometimes called "acne mechanica") can aggravate existing breakouts. Back acne is harder to treat than facial acne because the skin is thicker, follicles are larger, and many products are difficult to self-apply.

Chest acne

Chest acne in men is often associated with anabolic steroid use, high androgen levels, or excessive sweating. Men who spend time in hot environments or wear tight synthetic fabrics are more susceptible. Showering promptly after exercise and wearing breathable cotton fabrics significantly reduces chest acne flare-ups.

What type of acne do men commonly get?

Not all acne is the same, and the type you have affects which treatments work best.

Folliculitis vs acne

Men who shave regularly often experience folliculitis — bacterial or fungal infection of the hair follicle — which looks almost identical to regular acne. The key distinguishing feature: a folliculitis pustule usually has a hair shaft visible at its centre. Folliculitis on the face or neck from shaving (pseudofolliculitis barbae) is particularly common in men with curly hair. Treatment differs from acne vulgaris, so correct identification matters.

Rosacea: often mistaken for acne

Rosacea is a separate skin condition that causes facial redness and small pimples, typically across the nose and cheeks. It is often confused with acne because it looks similar, but it is not caused by excess oil or bacteria — and standard acne treatments can actually worsen it. If your "acne" comes with persistent facial flushing, visible blood vessels, or a burning sensation, rosacea may be the actual diagnosis. mymirror's analysis surfaces differences between rosacea and acne where they are visible in your image — though physical examination by a dermatologist remains the definitive route for distinguishing the two.

How to treat acne in men

Because men cannot use the hormonal treatments available to women, acne treatment in men follows a specific path — starting with skincare habits and over-the-counter products, then escalating to prescription options if needed.

Step 1: Get the basics right

Most men's skincare routines are either non-existent or far too aggressive (over-washing strips the skin of oil, triggering a compensatory increase in sebum production). An effective anti-acne routine for men is simple:

• Wash your face twice daily with a gentle, non-abrasive cleanser — avoid scrubs with beads or granules
• Use a lightweight, oil-free, non-comedogenic moisturiser — acne-prone skin still needs hydration
• Apply SPF 30+ sunscreen daily — UV exposure worsens post-acne dark marks (hyperpigmentation)
• Never pick or squeeze spots — this worsens inflammation and causes scarring
• Change your pillowcase at least twice a week

Step 2: Active OTC ingredients that work

Step 3: Prescription treatments for men

If OTC products haven't produced adequate results after 8 weeks, a dermatologist can prescribe:

• Prescription-strength topical retinoids (tretinoin, adapalene 0.3%) — significantly more effective than OTC retinol for clearing persistent acne
• Topical antibiotics (clindamycin, erythromycin) — typically used in combination with benzoyl peroxide to prevent antibiotic resistance
• Oral antibiotics (doxycycline, minocycline) — used for moderate to severe inflammatory acne; the American Academy of Dermatology recommends limiting courses to three months or less
• Isotretinoin (Accutane) — the most effective treatment for severe, scarring, or treatment-resistant acne. Shrinks the sebaceous glands, often producing lasting remission. Men do not have the pregnancy-related restrictions required for women, making it more straightforwardly accessible.

Shaving tips to reduce acne

• Use a fresh, sharp blade for every shave — dull blades drag and cause microscopic cuts
• Shave in the direction of hair growth (with the grain), not against it
• Use a non-comedogenic shaving gel or cream — not soap or dry
• If razor bumps are persistent, switch to an electric razor — it doesn't cut as close but causes significantly less follicle irritation
• Ask your dermatologist about antibiotic foam that can be mixed with shaving cream for severe cases

Diet changes that can make a difference

• Reduce high-glycaemic foods: white bread, sugary drinks, crisps, white rice
• Consider limiting dairy and whey protein if breakouts worsen after consumption
• Increase vegetables, legumes, whole grains, and fatty fish (omega-3s reduce inflammation)
• Drink at least 2 litres of water daily — dehydrated skin overproduces oil as a compensatory response

When should men see a dermatologist for acne?

Many men tolerate acne for years without seeking help, often dismissing it as something to push through. But acne can cause permanent physical scarring and significant psychological harm — and the longer it is left untreated, the more difficult it becomes to address. Research consistently shows that acne has a quality-of-life impact comparable to chronic medical conditions.

See a dermatologist if any of the following apply:

• OTC products haven't worked after 4–8 weeks of consistent use — this is the clearest sign you need something stronger
• Scarring is appearing — even small, early scars are a signal to escalate treatment immediately. Post-acne scars are difficult and expensive to treat; prevention is far better.
• Acne is affecting your confidence, sleep, or daily life — psychological impact is a medically valid reason to seek help. Men are less likely to acknowledge this, but it matters.
• You have painful cysts or nodules — deep, large lesions rarely respond to OTC products and require prescription treatment to prevent scarring
• Breakouts worsen suddenly without an obvious cause — rapid onset or worsening of adult acne can occasionally indicate an underlying hormonal condition worth investigating
