How to Treat Acne: Ingredients That Work and a Gentle Anti-Acne Routine
Acne is not caused by "dirty skin", and you can't scrub it away. Breakouts form when excess oil and dead skin cells clog a pore, bacteria multiply inside it and the skin reacts with inflammation. Treating acne well means targeting those steps with the right ingredients — and protecting your skin barrier while you do it. Here is what works, what to avoid, and a routine you can start tonight.
Quick answer: For mild to moderate acne, use a salicylic acid (BHA) cleanser to unclog pores, a niacinamide or azelaic acid serum to calm redness and marks, a light non-comedogenic moisturizer, and SPF 50 daily. Use pimple patches on active spots. Give any routine 6–8 weeks before judging it, and see a dermatologist for painful, cystic or scarring acne.
First, identify your type of breakout
| What you see | What it is | Ingredients that help |
|---|---|---|
| Black or white dots on the nose, chin, forehead | Blackheads / whiteheads (non-inflamed clogged pores) | Salicylic acid, clay masks — shop blackheads & whiteheads |
| Red bumps and pimples with a white head | Inflamed acne (papules, pustules) | Benzoyl peroxide, azelaic acid, salicylic acid |
| Flat brown or red marks after a pimple | Post-inflammatory marks | Niacinamide, azelaic acid, tranexamic acid, daily SPF — shop dark spots |
| Deep, painful lumps under the skin | Nodules / cysts | See a dermatologist — prescription treatment is usually needed |
| Breakouts on the back and chest | Body acne | BHA body wash or peel — shop body acne |
The ingredients that actually treat acne
Salicylic acid (BHA)
Oil-soluble, so it gets inside the pore and dissolves the mix of sebum and dead skin that forms blackheads. A cleanser is the gentlest way to start: the COSRX Salicylic Acid Daily Gentle Cleanser and the budget-friendly local NFRY Gentle Salicylic Acid Cleanser are two of our bestsellers. All options: salicylic acid.
Benzoyl peroxide
Targets acne-causing bacteria and is especially useful for red, inflamed pimples. It can be drying and can bleach towels and pillowcases, so start with a short-contact wash such as the PanOxyl Acne Gel Face Wash — massage it on, leave it for about a minute and rinse.
Azelaic acid
A gentle all-rounder: it helps with breakouts, redness and the marks pimples leave behind, and is generally well tolerated by sensitive skin. Try the Anua Azelaic Acid 10 + Hyaluron Redness Soothing Serum.
Niacinamide
Calms the look of redness, balances oil and fades post-acne marks over time. It pairs well with almost every other active. Options include the NFRY Clarifying Niacinamide Serum and Anua Niacinamide 10% + TXA 4% Serum for stubborn marks. Browse niacinamide.
Centella asiatica (cica)
The soothing hero of Korean skincare. It doesn't unclog pores on its own, but it helps calm irritated, breakout-prone skin — making it a great partner for stronger actives. Try SKIN1004 Madagascar Centella Ampoule and browse centella products.
Retinoids
Retinoids speed up cell turnover and are among the most effective long-term acne treatments, but they need a slow introduction and strict sun protection. Avoid them if you are pregnant or breastfeeding, and ask a dermatologist about prescription options. Over-the-counter options: retinol.
Don't combine everything at once. Using BHA, benzoyl peroxide and retinol on the same night is a fast way to irritate your skin — and irritated skin breaks out more. Introduce one active at a time, every 2–3 weeks.
A simple anti-acne routine
Morning
- Gentle cleanser (or your salicylic acid cleanser if your skin tolerates it daily)
- Niacinamide or azelaic acid serum
- Light gel moisturizer such as Purito Seoul Oat Calming Gel Cream
- SPF 50 — see our sunscreen guide for non-greasy picks
Evening
- Cleansing oil if you wore sunscreen or makeup (it won't clog pores when properly emulsified and rinsed)
- Salicylic acid cleanser or a BHA foam like Some By Mi AHA BHA PHA 30 Days Miracle Acne Clear Foam
- Treatment: azelaic acid, or a targeted product such as La Roche-Posay Effaclar Duo+M
- Barrier-supporting moisturizer, e.g. Dr. Althea 345 Relief Cream
- On active pimples: a hydrocolloid patch like COSRX Master Patch Clear Fit or Some By Mi Clear Spot Patch, or a spot treatment such as AXIS-Y Spot The Difference
If you also have very oily skin, the full step-by-step routine is in our Korean routine for oily skin.
Habits that help (and hurt)
- Don't pick or pop — it pushes bacteria deeper and leaves darker marks.
- Change pillowcases 2–3 times a week and clean your phone screen.
- Choose non-comedogenic makeup and remove it every night.
- Be patient — skin needs about 6–8 weeks to show real change; some products cause a short adjustment period.
- Protect your barrier — a red, stinging, flaky face is a sign to pause actives and focus on soothing products.
When to see a dermatologist: painful cysts or nodules, acne that leaves scars, acne that hasn't improved after 3 months of consistent care, or sudden adult acne with other symptoms (irregular periods, excess hair growth). This article is for general education and does not replace medical advice.

Frequently asked questions
What is the best treatment for acne?
For mild to moderate acne, a combination of a salicylic acid cleanser, a calming active such as azelaic acid or niacinamide, a light moisturizer and daily SPF works for most people. Severe, cystic or scarring acne needs a dermatologist.
What is the best cream for acne?
There is no single best cream for everyone. Azelaic acid serums and targeted treatments with salicylic acid or niacinamide suit most types of breakouts, while a non-comedogenic gel moisturizer keeps the skin barrier healthy during treatment.
How long does acne treatment take to work?
Most routines take 6–8 weeks of consistent use to show clear improvement. Introduce one new active at a time so you know what is working.
Do pimple patches work?
Hydrocolloid pimple patches absorb fluid from whiteheads, protect the spot from picking and help it heal faster. They work best on surface pimples, not deep cysts.
How do I get rid of blackheads?
Use salicylic acid (BHA) regularly to dissolve oil inside the pores, add a clay mask once a week and avoid squeezing. Niacinamide helps refine the look of pores over time.
