Acne Treatment: 7 Proven Options From Mild to Severe

Acne treatment works best when it is matched to the type and severity of your breakouts: mild blackheads and whiteheads usually respond to over-the-counter benzoyl peroxide, adapalene or salicylic acid, while deep, painful or scarring acne needs a doctor and often prescription tablets such as antibiotics, hormonal therapy or isotretinoin. Whatever you choose, expect to wait at least 6 to 8 weeks before you see fewer breakouts, and keep going once your skin clears.

How acne treatment works

Acne is a common skin condition that causes spots on the face, chest and back. It develops when hair follicles become blocked with excess oil (sebum) and dead skin cells; bacteria can then multiply inside the blocked follicle and cause inflammation and pus. Hormone changes during puberty, periods, pregnancy and menopause, conditions such as polycystic ovary syndrome (PCOS), certain medicines and greasy skin or hair products can all contribute.

It is extremely common. Cleveland Clinic estimates that about 80% of people aged 11 to 30 have at least a mild form of acne. It most often affects teenagers and young adults, but it can persist or start in adulthood, adult acne is more common in women, and a family history raises your risk.

Every effective acne treatment targets one or more of these steps in the process. Retinoids such as adapalene and tretinoin keep pores from clogging and calm inflammation. Benzoyl peroxide reduces acne-causing bacteria. Salicylic acid exfoliates and opens clogged pores. Antibiotics control bacteria and inflammation, hormonal therapy reduces the oil-driving effect of androgens, and isotretinoin shrinks the oil glands themselves. This is why dermatologists often combine two products with different mechanisms instead of relying on a single one.

Acne is not only a cosmetic problem. The NHS notes that it can cause anxiety, depression and low self-esteem, and untreated severe acne can lead to permanent scarring. Both are good reasons to start acne treatment early rather than waiting for it to “grow out.”

Acne grades: matching acne treatment to severity

Before choosing an acne treatment, it helps to know what kind of spots you have. Acne lesions fall into two broad groups:

Arabic-speaking readers: a detailed, source-referenced Arabic overview of this topic is available in the Alphateb medical encyclopedia — حب الشباب.

• Non-inflamed (comedones): whiteheads, which are small skin-colored bumps, and blackheads, which are flat black or brown spots in open pores.
• Inflamed: papules (raised bumps that look pink or red on white skin and brown or purple on darker skin), pustules (bumps filled with pus), and nodules and cysts, which are larger, often painful lumps under the skin that can join together.

Dermatologists use several grading systems. Cleveland Clinic describes a common four-grade scale:

• Grade 1 (mild): mostly whiteheads and blackheads, with a few papules and pustules.
• Grade 2 (moderate): multiple papules and pustules, mostly on the face.
• Grade 3 (moderately severe): numerous papules and pustules, occasional inflamed nodules, sometimes on the back and chest.
• Grade 4 (severe): numerous large, painful, inflamed pustules and nodules.

DermNet uses lesion counts instead: mild acne means fewer than 20 comedones, fewer than 15 inflammatory lesions or fewer than 30 lesions in total, while severe acne includes more than 5 pseudocysts or more than 125 lesions in total. Its general approach is topical treatment for mild acne, oral antibiotics and/or hormonal therapy for moderate acne, and a course of oral isotretinoin for severe acne. Your age, sex, how long you have had acne and how it responded to earlier acne treatment also shape the plan.

Over-the-counter acne treatment: benzoyl peroxide, adapalene and salicylic acid

For mild acne, the NHS and the American Academy of Dermatology (AAD) both point first to pharmacy acne treatment. Three ingredients have the best support for non-prescription acne treatment, and a pharmacist can help you pick a product.

Benzoyl peroxide

Benzoyl peroxide reduces acne-causing bacteria and works best when combined with another acne treatment, such as a retinoid. The AAD advises starting with a 2.5% product: strengths up to 10% exist, but higher concentrations raise the risk of dryness, irritation and burning. If 2.5% still irritates your skin, using it every other day is an option. The NHS says it usually starts to work within 4 weeks and that you should see a pharmacist or GP if acne has not improved after 12 weeks.

Two practical points: benzoyl peroxide can bleach clothing, towels, bedding and hair, so let it dry and keep it away from fabrics, and it makes skin more sensitive to sunlight. Common side effects are redness, stinging, dryness and peeling, which often ease within a few days or with less frequent use.

Adapalene

Adapalene is a retinoid that clears pores and treats blackheads, whiteheads and some pimples; it is often applied in the evening. In the US, the FDA switched adapalene 0.1% gel (Differin) from prescription to over-the-counter status in July 2016, and in May 2026 it added an over-the-counter gel combining adapalene 0.1% with benzoyl peroxide 2.5% for people aged 12 and older. Availability differs by country: in the UK, for example, the NHS lists adapalene among prescription topical retinoids.

Source: American Academy of Dermatology, U.S. FDA, NHS

Retinoids need to cover the whole acne-prone area, not just individual spots, and they often take months to show their full effect. Because they increase sun sensitivity, the AAD recommends a broad-spectrum sunscreen with SPF 30 or higher. If you are pregnant or planning a pregnancy, speak to a doctor before using any retinoid.

Salicylic acid

Salicylic acid opens clogged pores and exfoliates the skin, so it is most useful for whiteheads and blackheads. It is sold over the counter as cleansers and lotions in several strengths. Other non-prescription ingredients listed by MedlinePlus include sulfur and resorcinol; all of these can dry or peel the skin, so use them sparingly at first.

Source: American Academy of Dermatology (adult acne), Cleveland Clinic, MedlinePlus

The AAD’s main rule for over-the-counter acne treatment is patience: use one product as directed for 6 to 8 weeks without adding or stopping products. You may see fewer breakouts in 4 to 8 weeks, and clearing can take about 16 weeks. Apply a thin layer to all acne-prone skin to prevent new spots, not only the ones you can see.

Prescription acne treatment options

If over-the-counter acne treatment is not enough, or your acne is moderate to severe, a GP or dermatologist can prescribe stronger options.

Prescription creams and gels

Topical retinoids such as tretinoin, tazarotene and trifarotene reduce inflammation and oiliness and prevent new spots. Topical antibiotics such as clindamycin and erythromycin reduce bacteria and inflammation, but they should be used with benzoyl peroxide or a retinoid to lower the risk of antibiotic resistance; fixed combinations such as clindamycin 1% with benzoyl peroxide 5% exist for this reason. Azelaic acid opens pores, targets bacteria and also helps fade dark spots. Clascoterone cream (Winlevi) targets hormonal acne and is approved in the US for people aged 12 and older. Dapsone gel is another option for inflamed acne.

Antibiotic tablets

Oral antibiotics such as doxycycline, lymecycline, minocycline and sarecycline are used for moderate to severe inflamed acne. The AAD notes they are prescribed for the shortest time needed, usually several months, and they are not effective for nodular acne. Cleveland Clinic stresses that they are not a long-term cure, which is why they are paired with a topical acne treatment that you continue after the tablets stop.

Hormonal acne treatment

For women, certain combined birth control pills can treat acne by managing the hormones that drive oil production. Spironolactone is used for stubborn hormonal acne in women, often along the jawline, chest or back. It can cause serious birth defects, so pregnancy must be avoided while taking it.

Source: American Academy of Dermatology, NHS, Cleveland Clinic

In-office procedures

Dermatologists can inject a corticosteroid into a large, painful nodule to reduce swelling quickly; this is reserved for a few severe lesions. Chemical peels, laser or light therapy for mild to moderate acne, and extraction by a trained doctor are other in-clinic options that usually complement, rather than replace, daily acne treatment.

Isotretinoin: effectiveness and safety rules

Isotretinoin (formerly sold as Roaccutane and Accutane) is an oral retinoid that reduces oil production and inflammation. It is used for severe acne with deep, painful cysts and nodules, acne that causes scarring, or acne that has not cleared with other acne treatment. The AAD says it often leads to prolonged clearance, which can be permanent for some patients.

Source: American Academy of Dermatology (isotretinoin), NHS, MedlinePlus

Course length varies. The AAD describes a typical course of about four to five months, while the NHS says around 3 months; both note it can be shorter or longer, so your dermatologist will tailor it to you. The tablets are taken with food, and doctors order blood tests to monitor how you respond.

Pregnancy prevention

Isotretinoin causes severe birth defects and must not be taken by anyone who is pregnant or may become pregnant. In the US, patients, prescribers and pharmacies must all be registered in the iPLEDGE program; prescriptions cover 30 days without refills. People who can become pregnant need two negative pregnancy tests before starting, monthly tests during treatment, and tests at the end and 30 days after. They must use two forms of birth control from 1 month before until 1 month after treatment. In the UK, the NHS similarly requires effective contraception from at least 1 month before until at least 1 month after the course.

Mood and other side effects

Isotretinoin carries a warning about depression, psychosis and suicidal thoughts. Patients and families should watch for mood changes and contact a doctor immediately if they appear; the NHS says it is unsuitable for people with a history of depression or thoughts of self-harm. Common side effects include dry, cracked lips, dry skin, eyes and nose, nosebleeds and sun sensitivity, and the NHS also lists muscle and joint pain, headaches, erectile dysfunction and low sex drive.

Other rules during an isotretinoin acne treatment course: never share your tablets, do not donate blood during treatment or for 1 month after, avoid vitamin A supplements unless your doctor approves, avoid waxing and dermabrasion during treatment and for 6 months after because of scarring risk, and limit alcohol, which could affect the liver. Do not buy isotretinoin online.

A daily routine that supports acne treatment

Good skin care will not cure acne on its own, but harsh habits can undo any acne treatment. The AAD and NHS recommend:

• Wash gently up to twice a day and after sweating, using a mild, non-abrasive cleanser and your fingertips rather than washcloths or sponges.
• Avoid toners, astringents and scrubs, which can dry the skin and make acne worse.
• Remove make-up at the end of the day and choose products labeled “non-comedogenic” or “won’t clog pores,” including moisturizer and sunscreen.
• Do not pick, squeeze or pop spots; this slows healing and raises the risk of scars and dark marks.
• Wear loose, breathable clothing if you have body acne, and wash caps and hats regularly.

A simple order works well for most people: cleanser, then your acne treatment on dry skin, then an oil-free moisturizer, with sunscreen in the morning. Avoid switching products every week. The AAD warns that changing treatments too often can irritate the skin and trigger more breakouts, and it may take several weeks to a few months to see a difference.

If acne appears mainly on the forehead and temples, hair oils may be the cause. The AAD suggests switching to water- or glycerin-based hair products, or keeping oil away from the hairline. Heavy, oily skin products such as cocoa butter and shea butter can also clog pores on the face, chest and back.

Acne myths that get in the way of treatment

“Acne is caused by dirty skin”

Acne begins inside the follicle, through oil, dead skin cells, bacteria and hormones, not from surface dirt. Washing more often or scrubbing harder does not help; the NHS warns that scrubbing irritates the skin and can make acne worse.

Source: NHS, Cleveland Clinic

“Chocolate and greasy food cause acne”

MedlinePlus states that chocolate, nuts and greasy foods have not been shown to cause acne, while a link with refined sugar or dairy in some people is still debated. A review in the American Journal of Clinical Dermatology found the strongest, though still conflicting, evidence for high-glycemic diets: two randomized trials showed fewer lesions on low-glycemic-load diets. Evidence for milk, whey protein and chocolate comes mainly from observational studies and small case series, so it cannot prove cause and effect.

“Sun exposure clears acne”

Tanning is not an acne treatment. The AAD notes that tanning damages the skin and can worsen acne, and many acne medicines, including retinoids and benzoyl peroxide, make skin more sensitive to the sun.

Source: American Academy of Dermatology (skin care tips), NHS (benzoyl peroxide)

“Toothpaste dries out pimples”

Cleveland Clinic explains that toothpaste ingredients are designed for teeth and can leave a redder, more irritated pimple. A spot product containing benzoyl peroxide or salicylic acid is the better choice.

“If it doesn’t work in two weeks, it won’t work”

Most acne treatment needs at least 6 to 8 weeks before breakouts decrease. Stopping too early is one of the most common reasons people think nothing works.

Acne scars and dark spots: treatment after clearing

Scarring happens when inflammation damages the deeper layers of the skin. The risk is highest with deep, painful acne, in people who pick or squeeze their spots, and in those with a parent or sibling who has acne scars. Depressed (sunken) scars are the most common type; the NHS describes shallow holes known as ice-pick or boxcar scars. Raised scars, including keloids, can also form and are more common in skin of color, particularly along the jawline, chest and upper back.

Not every mark is a scar. Post-inflammatory hyperpigmentation is a flat dark spot left after a pimple heals. It usually fades over time, and azelaic acid or a retinoid can help. True scars rarely disappear on their own, but a dermatologist can make them less noticeable.

Scar treatment normally starts only once acne is under control and you are using acne treatment to prevent new breakouts. Options for depressed scars include chemical peels, fillers, laser resurfacing, microneedling (often combined with radiofrequency or platelet-rich plasma), radiofrequency, and scar surgery or dermabrasion under local anesthesia. Raised scars may be treated with lasers, corticosteroid injections or prescription medicine applied to the scar. Results usually need several sessions; mild chemical peels, for example, often involve 3 to 5 treatments spaced 2 to 4 weeks apart.

Source: American Academy of Dermatology (scar treatment)

Tell your dermatologist about any acne treatment you have used in the past two years, because some scar procedures can cause side effects if started during or soon after certain acne medicines; isotretinoin is one example, since waxing and dermabrasion should be avoided for 6 months afterwards.

When to see a doctor or dermatologist

Book an appointment with a GP or dermatologist if any of the following apply:

• Home acne treatment has not helped after a few months of consistent use.
• You have many spots, or deep, painful nodules or cysts.
• Your acne is leaving scars or dark marks.
• You notice signs of skin infection, such as hot, swollen, red skin.
• Acne is affecting your mood, confidence or social life.
• You are pregnant or trying to conceive, because many acne medicines are not safe in pregnancy.
• A sudden, severe outbreak appears in adulthood, which may need tests for an underlying condition.

A dermatologist can identify what is causing your breakouts, design a combined acne treatment plan, and lower your risk of scarring. The AAD stresses that no acne is too mild to benefit from a visit, and early treatment is the best scar prevention available.

Acne treatment: frequently asked questions

What is the fastest acne treatment?

There is no overnight cure. Benzoyl peroxide usually starts working within about 4 weeks, but most acne treatment needs 6 to 8 weeks to reduce breakouts. A corticosteroid injection by a dermatologist can shrink a single large, painful nodule quickly.

Source: NHS (benzoyl peroxide), American Academy of Dermatology

Can I use benzoyl peroxide and adapalene together?

Yes. The AAD notes that pairing a retinoid with benzoyl peroxide works well, and combination gels exist. Start slowly to limit dryness and irritation.

Which acne treatment is best for cystic acne?

Deep nodules and cysts need a doctor. Oral antibiotics are not effective for nodular acne, and isotretinoin is the usual treatment for severe nodular acne that has not responded to other options.

Source: American Academy of Dermatology, American Academy of Dermatology (isotretinoin)

Is isotretinoin safe?

It is effective for severe acne when properly supervised, but it causes severe birth defects and may affect mood. It requires pregnancy prevention, regular follow-up and blood tests.

Source: MedlinePlus (isotretinoin), NHS (isotretinoin)

Does acne treatment need to continue after my skin clears?

Usually, yes. Keep using a topical treatment, often a retinoid, to prevent new breakouts; antibiotics in particular are not a long-term cure.

Source: Cleveland Clinic, American Academy of Dermatology (scar treatment)

Is acne treatment safe during pregnancy?

Many topical and oral acne medicines are not safe in pregnancy, and isotretinoin and spironolactone must be avoided. Talk to a doctor before treating acne yourself if you are pregnant or trying to conceive.

Source: Cleveland Clinic, American Academy of Dermatology (adult acne), American Academy of Dermatology

Will my acne scars go away on their own?

Dark marks often fade, but true scars rarely disappear without treatment. Procedures such as peels, lasers, microneedling and fillers can improve them once acne is controlled.
