If you have woken up to a new pimple right before a big day, you are in very good company. Acne is the most common skin condition in the world, and it affects most teens at some point during puberty. The good news is that it is treatable, it is not caused by being "dirty," and a few simple habits can make a real difference.
Key takeaways
- Acne happens because puberty hormones make oil glands more active, not because you are doing something wrong.
- A gentle routine of washing twice a day, moisturizing and using sunscreen is the foundation of good skin care.
- Over-the-counter ingredients like benzoyl peroxide, salicylic acid and adapalene work well for mild to moderate acne.
- Treatments take 6 to 8 weeks to show results, so patience and consistency matter.
- See a doctor if acne is painful, leaves scars or affects how you feel about yourself.
Why puberty causes acne
During puberty, your body makes more hormones called androgens. These hormones are present in everyone, and they tell the tiny oil glands in your skin, called sebaceous glands, to produce more oil (sebum).
Acne forms when three things come together:
- Extra oil clogs the opening of a hair follicle, often called a pore.
- Dead skin cells that would normally shed get stuck in the pore with the oil.
- Bacteria that naturally live on skin multiply inside the clogged pore and cause redness and swelling.
Your face, chest, upper back and shoulders have the most oil glands, which is why acne usually shows up in those areas. Genetics also play a role. If a parent had acne as a teen, you may be more likely to have it too.
Types of acne
Knowing what you are looking at helps you choose the right care.
| Type | What it looks like | What is happening |
|---|---|---|
| Whiteheads | Small, flesh-coloured or white bumps | A pore is clogged and closed at the surface |
| Blackheads | Small dark dots | A pore is clogged but open; the dark colour comes from air reacting with oil, not dirt |
| Papules and pustules | Red bumps, sometimes with a white centre | The clogged pore has become inflamed |
| Nodules and cysts | Large, deep, painful lumps | Inflammation deep in the skin; more likely to scar |
Whiteheads and blackheads are often called "comedones." Most teens have a mix of types.

You do not need a cabinet full of products. A short routine done every day works better than a complicated one you forget about.
Morning
- Wash your face with lukewarm water and a gentle, fragrance-free cleanser.
- Pat dry with a clean towel instead of rubbing.
- Apply a light, oil-free moisturizer labelled "non-comedogenic," which means it is less likely to clog pores.
- Use a broad-spectrum sunscreen with SPF 30 or higher, especially if you use acne treatments that make skin more sensitive to the sun.
Evening
- Wash your face again, especially after sports or a sweaty day.
- Apply your acne treatment to the whole area where you tend to break out, not just on individual spots.
- Finish with moisturizer if your skin feels dry.
Everyday habits that help
- Keep your hands off your face as much as you can.
- Wash pillowcases weekly and clean your phone screen often.
- Shower after exercise, and change out of sweaty clothes.
- Pull long hair back from your face and wash hair regularly if it is oily.
- Choose makeup and hair products labelled oil-free or non-comedogenic.
Over-the-counter treatments that actually work
Several ingredients have strong research behind them and are widely recommended by dermatologists.
| Ingredient | How it helps | Tips |
|---|---|---|
| Benzoyl peroxide | Kills acne-causing bacteria and reduces inflammation | Start with a 2.5% to 5% strength; it can bleach towels and clothing |
| Salicylic acid | Helps unclog pores and loosen dead skin | Good for blackheads and whiteheads |
| Adapalene gel | A retinoid that keeps pores from clogging | Use a pea-sized amount at night; can cause dryness at first |
Start with one product at a time so you can see how your skin reacts. Mild dryness, peeling or redness in the first few weeks is common. If your skin becomes very irritated, try using the product every other day, and check in with a pharmacist or doctor.
Myths to let go of
- "Acne means you are not clean." Acne starts below the skin's surface. Over-washing can actually make it worse.
- "Toothpaste dries out pimples." Toothpaste can irritate and burn skin. Stick with products made for acne.
- "The sun clears up acne." A tan can hide redness for a short time, but sun damage harms skin and some acne medicines make you burn more easily.
- "You just have to wait it out." Effective treatment is available, and starting early can help prevent scarring.
Acne and your feelings
Acne is a physical condition, but it can affect how you feel. It is normal to feel frustrated or self-conscious. Try to remember that almost everyone around you is dealing with skin changes too, and that your worth has nothing to do with your complexion.
If acne is making you want to skip school, avoid friends or stop doing things you enjoy, that is an important reason to get help. Talking to a parent, school nurse or doctor can lead to treatment that helps both your skin and your confidence.
When to talk to a doctor
Plenty of acne improves with over-the-counter care, but some situations call for a doctor or a dermatologist, a doctor who specializes in skin. Ask a parent or trusted adult to help you book an appointment if:
- You have tried an over-the-counter routine consistently for 2 to 3 months without improvement.
- You have deep, painful lumps or cysts.
- Acne is leaving dark marks or scars.
- Your skin becomes very red, swollen or irritated from treatments.
- Acne is affecting your mood, sleep or self-esteem.
A doctor can prescribe stronger treatments, such as prescription creams, antibiotics for a limited time, or other medicines suited to your skin. They will explain how each one works and what side effects to watch for.
The bottom line
Acne during puberty is extremely common and is caused by normal hormone changes, not by anything you did wrong. A gentle daily routine, the right over-the-counter ingredient and a little patience help most teens see clearer skin. If your acne is stubborn, painful or getting you down, a doctor can help, so do not hesitate to ask.
Frequently asked questions
Does eating chocolate or greasy food cause acne?
For most people, no single food causes acne. Some research suggests high-sugar foods and lots of dairy may make breakouts worse for certain people, so it is reasonable to notice your own patterns without cutting out whole food groups.
How long does it take for acne treatment to work?
Most over-the-counter and prescription treatments need about 6 to 8 weeks of steady use before you see a clear improvement. Skin may look a little worse in the first couple of weeks before it gets better.
Is it okay to pop pimples?
It is best not to. Squeezing pushes bacteria and oil deeper into the skin, which can cause more swelling, dark marks and permanent scars.
Can washing my face more often clear my acne?
Washing twice a day is enough. Scrubbing harder or more often can irritate skin and make acne worse, not better.
