How sensitive your skin isBenzoyl peroxide’s label rules out very sensitive skin, so sensitive skin routes to the gentler azelaic acid (FDA, AAD).

Which acne treatment for which breakout

In shortClogged pores: salicylic acid or a retinoid. Red, inflamed pimples: benzoyl peroxide.

Azelaic acid is the gentler one for sensitive skin, and on the back and chest the AAD builds its routine around a benzoyl peroxide wash. Whichever you pick, start one active at a time.

Match the treatment to the breakout

Clogged pores, not red or sore

Blackheads & whiteheads: salicylic acid

Blackheads and whiteheads are clogged pores, not inflammation. A BHA is oil-soluble, so it works inside the pore: DermNet says salicylic acid helps break down blackheads and whiteheads, and the AAD says it opens clogged pores and exfoliates.

Sensitive skin: azelaic acid. On sensitive skin, azelaic acid is the gentler route to clear pores: Cleveland Clinic lists it among comedonal-acne treatments, the AAD says it opens clogged pores, and it is one of the gentler actives.

Want more? A retinoid unclogs pores too: the AAD treats blackheads and whiteheads with a retinoid (adapalene 0.1% is the over-the-counter one) plus a benzoyl peroxide wash — but add just one new active at a time.

Sore bumps, some with a white head

Red pimples & pustules: benzoyl peroxide

Red, sore pimples are inflamed. Benzoyl peroxide lowers the acne bacteria behind them: the AAD suggests a benzoyl peroxide (or salicylic acid) wash for papules and pustules, and says it works best with a second treatment.

Sensitive skin: azelaic acid. On sensitive skin, standard benzoyl peroxide can be too drying, so azelaic acid is the gentler pick: its 20% cream is FDA-labeled for mild to moderate inflammatory acne, and it calms inflammation.

Salicylic acid is the AAD’s other wash for red pimples. Whichever you pick, don’t pop them, and use one acne medicine at a time.

Clogged pores and red bumps

A mix of both: adapalene

A mix needs something that works on both. Adapalene is a retinoid: the AAD says retinoids clear pores and treat blackheads, whiteheads and some pimples, and its 2024 guideline gives them a strong recommendation. Adapalene 0.1% is sold without a prescription.

Sensitive skin: azelaic acid. On sensitive skin, azelaic acid covers both in one gentler active: the AAD says it opens clogged pores, works on acne bacteria and reduces inflammation.

Adapalene pairs well with a benzoyl peroxide wash — Mayo Clinic suggests one in the morning and one at night — but start one active first and add the other only once your skin has settled.

A larger area, thicker skin

Mostly on back or chest: a benzoyl peroxide wash

On the back and chest the skin is thicker and the area is large, so the AAD builds its routine around a foaming benzoyl peroxide wash: use it daily and leave it on two to five minutes before rinsing.

Sensitive skin. Still benzoyl peroxide, but the gentler wash: the AAD says a 5.3% wash is less likely to dry or peel skin than a stronger one (10% is the strongest without a prescription).

A wash rinses off, which also keeps benzoyl peroxide from bleaching sheets and towels. No loofahs or hard scrubbing, and change out of sweaty clothes soon.

AAD: back acne

The over-the-counter actives, one by one

BHA · Into the pore

Salicylic acid

A BHA: it is oil-soluble, so it gets into the pore and helps break down blackheads and whiteheads; the AAD says it opens clogged pores and exfoliates.

Sold as: 0.5% to 2%, OTC drug
Start: A thin layer, once a day

Pick a wash or leave-on with 0.5% to 2% salicylic acid — the range the FDA allows. Anything stronger is a wart remover, not for the face.
Start with one application a day on clean skin; add a second only if you need it, and drop back if your skin gets dry.
Patch-test first (the FDA advises 3 days on one or two small spots), wear sunscreen by day, and give it 6 to 8 weeks.

On bacteria · On the bacteria

Benzoyl peroxide

It lowers the bacteria behind inflamed acne (AAD), and dermatologists say it works best alongside a second acne treatment.

Sold as: 2.5% to 10%, OTC drug
Start: Start at 2.5%, once a day

Start at 2.5% in a water-based product: Mayo Clinic says the lowest strength works about as well, with less risk of side effects.
The label’s optional 3-day test, then a thin layer once a day; more won’t work faster, and you go to twice only if you need it.
It bleaches hair, towels and dyed fabric — let it dry first — and NHS says it usually starts working within 4 weeks.

Wash · Over a large area

Benzoyl peroxide wash

It lowers the bacteria behind acne (AAD); on the back and chest the AAD builds its routine around a foaming benzoyl peroxide wash.

Sold as: 2.5% to 10% wash, OTC drug
Start: A foaming wash, every day

Use a foaming benzoyl peroxide wash every day and leave it on two to five minutes before rinsing — that helps it work on the thicker skin of the back.
A 5.3% wash is less likely to dry or peel than a stronger one; 10% is the strongest without a prescription. No loofahs or hard scrubbing.
Rinsing keeps it from bleaching sheets and towels. Expect results in 6 to 8 weeks, and clearing in 3 to 4 months.

AAD: acne treatment AAD: back acne

Retinoid · Clears the pore

Adapalene

A retinoid: it unclogs pores and treats blackheads, whiteheads and some pimples (AAD). Adapalene 0.1% is the one sold without a prescription.

Sold as: 0.1% over the counter
Start: Once a day, at night

Once a day, at night: a thin layer over the whole area that breaks out, not just the spots — and never more than once a day.
Acne may look worse before it improves in the first weeks; the label calls this normal. Limit sun and don’t wax where you apply it.
Give it at least 6 to 8 weeks, up to 3 months. No change after 3 months? Stop and ask a doctor.

Gentler · Pores + calms

Azelaic acid

It keeps pores from plugging, works on acne bacteria, calms inflammation and fades the marks acne leaves — one of the gentler actives.

Sold as: 10% over the counter
Start: Once a day, then twice

The 10% is the strength sold without a prescription. DermNet’s gentle start: once a day on clean, dry skin, then twice a day if your skin tolerates it.
Itching, burning or stinging can show up at the start and usually eases. On darker skin, watch for lighter patches.
Most acne improves within about 4 weeks on the cream; DermNet says the best results come by 6 months.

Questions people ask

What is the best treatment for blackheads and whiteheads?

What is the best treatment for red, inflamed pimples?

Benzoyl peroxide or salicylic acid: which one should I use?

They do different jobs. A BHA: it is oil-soluble, so it gets into the pore and helps break down blackheads and whiteheads; the AAD says it opens clogged pores and exfoliates. It lowers the bacteria behind inflamed acne (AAD), and dermatologists say it works best alongside a second acne treatment.

What treats acne on the back and chest?

On the back and chest the skin is thicker and the area is large, so the AAD builds its routine around a foaming benzoyl peroxide wash: use it daily and leave it on two to five minutes before rinsing.

What is the gentlest acne treatment for sensitive skin?

It keeps pores from plugging, works on acne bacteria, calms inflammation and fades the marks acne leaves — one of the gentler actives. The 10% is the strength sold without a prescription. DermNet’s gentle start: once a day on clean, dry skin, then twice a day if your skin tolerates it.

How long does an acne treatment take to work?

It depends on the active. Salicylic acid: give it 6 to 8 weeks. Benzoyl peroxide: the NHS says it usually starts working within 4 weeks. Adapalene: at least 6 to 8 weeks, up to 3 months. Azelaic acid: most acne improves within about 4 weeks on the cream.

Can I use two acne treatments at once?

Adapalene pairs well with a benzoyl peroxide wash — Mayo Clinic suggests one in the morning and one at night — but start one active first and add the other only once your skin has settled.
