Teen Acne: A Practical Guide for Teenagers and Parents

Acne is so common during adolescence that it is almost a normal part of growing up. Most teenagers experience at least some spots, and for many it is more than a minor annoyance: it can affect confidence, mood and how comfortable they feel at school or with friends. The good news is that teen acne usually responds well to simple, consistent care, and effective medical help is available when needed.

Why acne starts in puberty

During puberty, rising levels of hormones called androgens stimulate the oil glands in the skin to grow and produce more sebum. At the same time, skin cells lining the pores can become sticky and clump together. Oil and dead cells form a plug, creating blackheads and whiteheads. Bacteria that normally live on the skin can then multiply in the blocked pore, causing red, inflamed pimples.

This process is driven mostly by hormones and genetics, not by dirt or poor hygiene. Our guide to types of acne explains the different spots you may see.

Common myths teens hear

“Acne means you are not washing enough.” Not true. Over-washing and scrubbing can actually make acne worse.
“Chocolate causes acne.” The evidence is weaker than people think, though some individuals notice links with certain foods. See our article on diet and acne.
“Just let it run its course.” Acne can last years and leave scars. Treating it early is sensible.
“Toothpaste dries out spots.” It can irritate skin and is not a treatment. Read more in common acne myths.

A simple routine that works

Teenagers do not need a ten-step routine or expensive products. Three or four steps done consistently are enough for most mild acne:

Morning: gentle cleanser, a light non-comedogenic moisturiser and sunscreen.
Evening: gentle cleanser, then an acne treatment such as benzoyl peroxide (2.5–5%) or adapalene gel, then moisturiser.
After sport: rinse or cleanse and change out of sweaty clothes.

Start treatment products every other night and increase to nightly as the skin adjusts. Mild dryness and peeling in the first few weeks are common. A moisturiser helps.

Patience is part of the treatment

Acne treatments take six to twelve weeks to show clear results. Many teenagers give up after a week or two, or switch products constantly, which means nothing gets a fair chance. It helps to take a photo at the start and compare after two months.

Habits that help

Try not to pick, squeeze or pop spots, which can lead to marks and scars. Hydrocolloid patches can help resist the urge.
Keep hair products and fringes off the forehead.
Change pillowcases regularly and clean phone screens.
Use non-comedogenic makeup and remove it before bed.
Get enough sleep and look after stress levels as much as possible.

Tips for parents

Take it seriously: acne can have a real impact on self-esteem and mood. Avoid comments that suggest it is caused by laziness or poor hygiene.
Help with consistency: buying simple products and helping establish a routine can make a big difference.
Watch for emotional impact: withdrawal, low mood or avoiding social situations because of skin are reasons to seek help.
Do not wait too long: if acne is moderate, painful or scarring, a doctor’s appointment is worthwhile.

When to see a doctor

See a doctor if acne has not improved after two to three months of regular over-the-counter treatment, if there are painful lumps or cysts, if spots are leaving scars or dark marks, or if acne is affecting mood or confidence. Doctors can prescribe stronger topical treatments, oral medicines and, for severe cases, refer to a dermatologist.

The bottom line

Teen acne is common, not caused by being dirty, and very treatable. A gentle routine with one proven treatment, used consistently for a couple of months, helps most teenagers, and there is no need to struggle alone if it does not.
