Strong evidenceThe strongest thing you can buy without a prescription, and the best first move for most acne. It unclogs pores before they inflame, which is why it prevents spots rather than treating them.
Blackheads and whiteheads point toward acne. Flushing, lasting facial color changes, and burning or stinging point toward rosacea. Both can cause pimples—and you can have both.


The same eight facts on every condition comparison.

Comedonal acne Mostly blackheads and whiteheads.

Inflammatory acne Red papules and pustules.

Nodulocystic acne Deep painful lumps that can scar.

Hormonal acne Breakouts along the jaw and chin.

Body acne On the chest, back and shoulders.

Erythematotelangiectatic rosacea Type 1 · Redness, flushing and visible vessels

Papulopustular rosacea Type 2 · Bumps and pimples

Phymatous rosacea Type 3 · Thickened skin

Ocular rosacea Type 4 · Eye involvement
Oil and shed skin cells can block a hair follicle, changing the environment inside the pore. Bacterial activity and the immune response contribute to inflammation, swelling and tender spots.
Rosacea involves inflammatory activity and unusually reactive blood vessels in facial skin. These changes can produce flushing, persistent color changes, visible vessels or bumps, with different features in different people.
Acne. Acne Often in teens Often begins in the teen years; acne can continue or first appear in adulthood.
Rosacea. Rosacea Usually 30–60 Usually begins in adulthood, often between ages 30 and 60. Starting ages can vary.
Acne forms when oil and dead skin cells clog pores, acne bacteria grow inside them, and inflammation follows. Hormones that increase oil play a central role.
Oil and dead skin cells block hair follicles. Bacteria within the follicles and inflammation contribute to pimples and deeper spots. Hormonal changes can increase oil production.
Rosacea involves overactive blood vessels and immune signals in the facial skin. Demodex mites, which live on everyone's skin, may also play a part.
Inflammation, sensitive skin, and changes in blood-vessel responses play a part. The skin barrier may be affected too. The exact cause is not fully understood.
Acne often runs in families. A parent with severe acne raises the chance of severe acne.
Acne can run in families. A close relative with deep, painful acne increases the chance of developing that pattern.
It often runs in families and is more common in people with fair skin, though it occurs in all skin tones.
Rosacea can run in families. Several inherited factors may contribute; there is no single gene that explains every case.
Evidence labels come from each condition’s own treatment list.

The strongest thing you can buy without a prescription, and the best first move for most acne. It unclogs pores before they inflame, which is why it prevents spots rather than treating them.

Kills the bacteria involved in inflamed spots, and is the one thing that stops acne bacteria becoming resistant to antibiotics. Lower strengths work about as well as higher ones and sting less. It bleaches towels and pillowcases.

Works on the spot and the mark it leaves at the same time, which makes it useful on deeper skin tones. It is also one of the few acne treatments considered safe in pregnancy.

Gets inside the pore and loosens the plug, so it suits blackheads and whiteheads more than deep spots. Gentler than a retinoid, and weaker than one.

Sold heavily for acne, and the evidence for clearing spots is thin. It is genuinely useful for the marks left behind and for tolerating stronger actives - just not as the treatment itself.

An old treatment, usually a mask or a spot dab, that dries the surface of a spot and mildly loosens plugs. It is gentle enough for skin that cannot tolerate benzoyl peroxide or a retinoid. It smells, and it is weaker than everything above it on this list.

A 5 percent gel reduces inflamed spots in small studies, more slowly than benzoyl peroxide does. Neat oil straight from the bottle is a common cause of an itchy rash, so buy it already diluted. It is a reasonable extra rather than something to build a routine on.

The one over-the-counter active with real evidence behind it in rosacea. At 10 percent it reduces the bumps and some of the redness, and it is better tolerated by reactive skin than acids or retinoids. Start every other night over moisturizer. The 15 percent prescription gel works better if this is not enough.

A mild anti-inflammatory that also helps the barrier hold water, which is the part of rosacea it is most useful for. Some people find it takes the edge off redness and stinging. It will not clear bumps and it does nothing for visible vessels, so treat it as support rather than treatment.

Sold widely for facial redness on the strength of small studies. It is soothing, it is unlikely to irritate, and some people like how their skin feels on it. There is no good evidence it changes flushing, bumps or visible vessels, so do not let it delay a prescription that would.

The most studied topical in acne. Stronger than adapalene and more irritating with it, so it is usually the step up rather than the starting point. Not used in pregnancy.

A newer retinoid, and the one specifically tested on chest and back acne rather than just the face. Useful when the trunk is the main problem. Expensive without coverage.

Calms inflamed spots, but should never be used on its own. Guidelines are explicit about this - alone it stops working within months as bacteria adapt, so it is always paired with benzoyl peroxide or a retinoid.

The strongest of the prescription retinoids, and the step to take when tretinoin has stopped making a difference. It is particularly good on stubborn blackheads and whiteheads. It is also the most irritating of them, so it is usually started two or three nights a week. Not used in pregnancy.

Blocks the hormone signal that drives oil production, but only where you put it. It is the first hormonal option that works topically, and the only one that can be used by men as well as women.

Mild on the skin and tends to suit adult women with inflamed spots who cannot tolerate a retinoid. Applied at the same time as benzoyl peroxide it can temporarily stain skin orange, so space them apart.

Often the best single treatment for the bumps and pus-filled spots, because it works on the Demodex mites and on the inflammation at the same time. Once a night, a pea-sized amount for the whole face. It usually beats metronidazole head to head, and it does nothing at all for flushing or visible vessels.

A prescription-strength gel or foam for the bumps, and one of the better options if your skin is too reactive for other creams. It also helps the marks rosacea leaves behind on deeper skin tones. Expect stinging for the first week or two, which usually settles if you apply it over moisturizer.

The longest-established prescription cream for rosacea bumps, used once or twice a day, and generally very well tolerated. It is a reasonable first choice and a common maintenance treatment once things are controlled. Newer options often work a little better, and none of them touch the redness itself.

An antibiotic put on the skin rather than swallowed, for the bumps. It suits people who would rather not take tablets, or who cannot. It is newer and usually more expensive than the older creams, and like them it does nothing for flushing or vessels.

A gel that narrows facial vessels and takes the redness down for several hours at a time. It treats nothing — it borrows time, and everything comes back when it wears off. Some people get rebound redness worse than they started with, so test a small area before you use it on the whole face and before any event that matters.

The same idea as brimonidine, using a different vessel-narrowing drug, applied once each morning. Rebound redness is reported less often with it, which is why some people move across after a poor experience. It still only lasts the day, and it does not stop rosacea progressing.

Brings widespread inflamed acne down quickly, and is meant to be used for three to four months, not indefinitely. Always alongside a topical, which is what carries on once the tablets stop.

The only acne treatment that often produces lasting clearance after the course ends. What it costs you is months of dry lips and skin, blood tests, and strict pregnancy prevention. For acne that scars, that trade is usually worth making early rather than late.

For the pattern rather than the individual spot - deep jawline acne in adult women that flares with the cycle. It works slowly, over three to six months, and can be continued long term. Not used in pregnancy.

Lowers the hormone signal driving oil production across the whole body, so it suits acne on the chest and back as well as the face. Takes about three months to show, and carries a small clot risk that needs weighing up.

Another tetracycline antibiotic for widespread inflamed acne, used the same way as doxycycline: three to four months, always alongside a topical. It is usually kept as the second choice, because it carries rarer but more serious side effects, including a blue-gray skin discoloration with long use.

A narrow-spectrum antibiotic designed specifically for acne, so it disturbs gut bacteria less than doxycycline. One tablet a day, still meant for three to four months and still alongside a topical. It works about as well rather than better, and it is considerably more expensive.

Low-dose Doxycycline. A 40 mg dose taken once a day, deliberately too low to act as an antibiotic — it is used purely for its anti-inflammatory effect, which means it does not drive antibiotic resistance. This is the usual next step for moderate to severe bumps when creams alone are not holding them, and it also helps ocular rosacea. It is normally stepped down to a cream once things settle.

Accutane at a low dose. Low-dose isotretinoin under specialist care, for severe bumps that tablets and creams have not controlled, or for early skin thickening. It works well, and it is not a cure — rosacea usually returns after the course. It requires strict pregnancy prevention and monitoring, so it is a considered decision rather than a routine step.

An alternative tablet for the bumps when doxycycline does not suit or has not worked. It is used at full antibiotic doses, so it is generally kept for shorter courses. It can cause dizziness, and rarely a blue-gray discoloration of the skin with long use, so it is not the first tablet reached for.

Low doses of propranolol or carvedilol are sometimes tried when flushing is the dominant problem and nothing else has touched it. The evidence is small studies rather than trials, and they lower blood pressure and slow the heart, so they do not suit everyone. Worth asking about only after triggers, laser and light have been addressed.

Deals with one stubborn painful lump, not the condition. It settles in a day or two and is the safe alternative to squeezing it. It does nothing to prevent the next one.

Clears blackheads that are already there, quickly and visibly. It does not stop new ones forming, so it is an add-on to a retinoid rather than a substitute for one.

Modest benefit for clogged pores and a better one for the dark marks left behind. Needs repeat sessions, and the benefit fades if the daily treatment stops.

Heats the oil glands themselves, which is a genuinely different approach from everything else on this page. Trial results out to about six months are good, it works across skin tones, and it is expensive and rarely covered. Long-term data is still limited.

Can help stubborn inflamed acne, but the protocols vary widely between clinics, the downtime is real, and the evidence is not strong enough to put it ahead of the options above.

Blue light kills acne bacteria at the surface, so a course can quiet mild inflamed spots for a while. The effect fades within weeks of stopping, and it does nothing for blackheads or deep lumps. In-clinic courses cost far more than a topical that would do more.
The treatment of choice for visible thread veins and settled background redness — the parts of rosacea that creams and tablets do not touch. It targets the blood in the vessel and closes it. Expect a course of about three sessions rather than one, expect bruising for a few days at stronger settings, and expect occasional top-ups, because rosacea carries on making new vessels.
IPL. Light rather than laser, and about as effective as pulsed dye laser for diffuse redness across the cheeks, with less bruising. It is often the better choice when the problem is a general flush rather than a few distinct threads. It needs an experienced practitioner and a test patch on deeper skin tones, because the wrong settings can cause lasting pigment change.

A longer wavelength that reaches deeper, larger vessels — the thicker blue-red threads beside the nose that pulsed dye laser sometimes leaves behind. It is also the device more often chosen for deeper skin tones, because it passes over surface pigment more safely. It is less useful for general background redness.

Used to reshape a nose that has thickened, by removing the excess tissue layer by layer. This is the answer for rhinophyma, since creams and tablets do not reverse it. It is a real procedure with real downtime of a couple of weeks, and results are strongly dependent on who does it.

Asked about constantly, usually as a home device. Red and near-infrared light is mildly anti-inflammatory and it is very unlikely to do harm. There is no good evidence it clears rosacea bumps or removes vessels, so it is a pleasant addition rather than a substitute for the treatments that do.
Botox. Very small amounts injected into the surface of the skin, not the muscle, to reduce flushing and background redness. Early studies are encouraging and dermatologists do use it for stubborn flushing. It is off-label for rosacea, it is not usually covered, and it wears off in a few months.
Have both?
Acne and rosacea can occur together. A treatment plan may need to address blocked pores, inflamed bumps, flushing, and sensitive skin separately.
Acne is usually controlled rather than permanently cured. Treatment reduces new breakouts, but improvement takes time and maintenance may be needed. Deep or scarring acne deserves early assessment because existing scars may remain after the active spots settle.
Rosacea runs in flares and quiet spells. The outlook is good - it does not scar, it is not dangerous, and treatment controls most of it. It does not go away, so the goal is long-term control on the lightest treatment that holds it.
Dark marks
Flat brown or violet patches left where a spot was. They are not scars and they do fade, but it commonly takes 6 - 12 months, and sun exposure makes them last longer. These WILL FADE with time.
Redness
Flat pink or red marks left where a spot was, most often on lighter skin. Also not scars. They usually settle on their own, though it can take several months. These WILL FADE with time.
Scars
Permanent dents, pits or raised bumps left where inflammation broke down the skin's structure. Once formed, they can only be improved by procedures. These WILL NOT FADE with time.
Depression and anxiety
Acne can affect self-esteem, confidence and mental health. The link is consistent, and it does not track with how severe the acne looks to anyone else - which is itself a reason to treat it.
Family conflict
This is very common. Acne visits involving a teenager and a parent can sometimes be challenging, particularly when there is ongoing conflict about acne care.
Social impact
People may avoid photos, dating, social situations or activities because of their skin.
Rhinophyma — thickening of the nose
Over years, the skin of the nose can thicken, enlarge and take on a bumpy, uneven surface. It develops slowly and only in a minority of people, and it is far more common in men. Creams and tablets do not reverse it once it is established, which is the strongest practical reason to treat rosacea early. It has nothing to do with drinking, despite an old and persistent belief that it does.
Ocular rosacea
Rosacea in the eyes causes gritty, dry, burning, watery or red eyes, crusting along the lash line and repeated styes. It affects a large share of people with rosacea, it can turn up before any skin changes, and it does not track with how bad the face looks. It is the part most often missed, and it needs treating in its own right, so mention your eyes even if nobody asks.
Lasting redness and visible vessels
Left to run for years, the redness stops fading between flushes and becomes the background color of the cheeks and nose, with fine vessels showing as permanent red threads. Creams do very little for this stage. Laser and light treatment work well on it, but preventing it is far easier than removing it, which is the practical argument for treating rosacea early.
Seek help for painful deep spots, scarring, persistent breakouts, or an uncertain diagnosis. Earlier treatment can reduce the chance of more scars.
Do not assume eye symptoms are part of acne. They need their own assessment.
Seek help for repeated flushing, lasting facial changes, products that repeatedly sting, or persistent gritty eyes and eyelid irritation.
Tell the clinician about dry or gritty eyes and sore lids, even when facial symptoms seem mild.
Blackheads are not typical of rosacea itself. If you have them along with flushing or rosacea-like bumps, acne may be present too.
They are separate conditions. Acne in your teens does not mean it has changed into rosacea later. New adult symptoms may be acne, rosacea, both, or another condition.
Yes. Bumps may be the most noticeable feature. Redness can be subtle, especially on darker skin, so warmth, sensitivity, flushing, and eye symptoms may help guide an assessment.
Some medicines overlap, but many do not. The choice should account for blocked pores, inflammation, flushing, and skin tolerance. Product strengths and doses can differ.
No. Neither acne nor rosacea spreads from person to person through ordinary contact.
No. Flushing can have other causes and can be a normal response to heat or emotion. Repeated flushing with lasting changes, bumps, sensitivity, or eye symptoms deserves assessment.
For most people it settles by the mid-twenties. About one in six women still has it into her 30s and 40s, and it can return after pregnancy, after stopping the pill, or with any hormone shift. Controlled rather than cured.
Less than the internet suggests. The evidence points at high-glycemic diets - sugar and refined carbohydrate - and, less consistently, at skim milk. Chocolate and greasy food never held up, and no diet replaces treating the skin.
That is purging. Retinoids speed up clogs already forming under the surface, so weeks of spots arrive at once. It peaks around weeks two to six and settles by week eight. Still worsening past 10 to 12 weeks is irritation, not purging.
No. Squeezing pushes the contents sideways into surrounding skin, turning a spot that would have gone in days into a mark that lasts months, or a scar that lasts forever. A large, painful lump can be injected in clinic instead, and settles in a day or two.
Sometimes, but never alone and never for long. They go alongside benzoyl peroxide or a retinoid, usually for three to four months, then stop while the topical carries on. Alone or indefinitely, they stop working and drive resistance.
Almost all acne is hormonal - hormones drive oil production. The label only matters if it changes treatment: deep spots along the jawline and lower face in an adult woman, flaring before periods, usually respond better to hormonal treatment than to antibiotics.
For most people it persists. It responds well to treatment, and many people keep it almost entirely controlled for years on light maintenance. The goal is control rather than cure, and treating early prevents the parts that become permanent.
No. Food and drink trigger flushing in someone who already has rosacea; they do not cause it. Hot drinks, alcohol and spicy food are reported most. Your triggers are personal - a couple of weeks of notes tells you more than any generic list. Cutting out foods that are not triggering you achieves nothing.
Sometimes, carefully. Both irritate, and a weakened barrier means many people cannot tolerate them at usual strengths. If you try, add one at a time, two or three nights a week over moisturizer, and stop if it stings. Never start one during a flare.
Laser and intense pulsed light are the only treatments that meaningfully remove visible vessels and reduce established redness, and results last a long time. Not permanently - rosacea continues and new vessels form, so most people need occasional maintenance sessions. Expect a series rather than one. On deeper skin tones, ask for an experienced practitioner and a test patch.
It can be both, and they feed each other. Hot flashes cause repeated flushing, and repeated flushing makes rosacea more visible. Rosacea flushing stays on the central face with bumps, visible vessels and sensitivity, while hot flashes involve the whole body, sweating and a sudden onset. Mention both to your doctor - managing one usually helps the other.
Yes, and worth doing if it helps. Green-tinted primers and color-correcting products neutralize redness well, and mineral foundations are generally well tolerated. What matters more than the brand is how you take it off - a gentle cream or micellar remover, not scrubbing or a wipe.
