Teenage skin needs three products, not a routine copied from someone twice its age. Most of what goes wrong at this stage comes from doing too much too early — a fifteen-year-old on an anti-ageing serum is spending money on a problem they do not have while irritating skin that was fine.

What is actually happening
Hormones raise oil production, pores block more easily, and the skin renews faster than it will at any later point. That means breakouts, shine, and a barrier that is generally robust — teenage skin tolerates more than adult skin does, which is exactly why it gets over-treated.
It also means most of it settles on its own. The job at this stage is to keep things calm and avoid creating damage that outlasts the teenage years.

The first routine
- A gentle cleanser, twice a day. Not a scrub, not anything that leaves skin squeaky.
- A light moisturiser, every day. This is the step teenagers skip because their skin is oily, and skipping it is what makes it oilier.
- Sunscreen. Starting at fifteen rather than thirty-five is worth more than every other decision on this page combined.
That is the whole thing. If there are breakouts, one active goes on top: salicylic acid two or three times a week, or benzoyl peroxide as a spot treatment. One. Not both, and not a six-step set bought together.

What to keep away from
- Anti-ageing products. There is nothing to prevent yet that sunscreen does not prevent better and cheaper.
- Retinol, at this stage. Unless a doctor has prescribed something for acne, there is no reason for it.
- Scrubs and alcohol toners. They feel like they are working and they drive the oil-and-irritation loop.
- Stacking actives. Three products with acids in them is daily exfoliation nobody intended.
- Squeezing. The marks left at sixteen are the ones people ask me about at twenty-six.

Buy the three basics and let that be the whole conversation for a few months. Resist the urge to add something every time there is a breakout — adding is what teenagers do on their own, and the useful adult contribution is usually subtraction.
Deep, painful spots that leave marks are the exception. Those are worth seeing a doctor about early rather than working through a shelf first, because that kind of acne scars and the window to prevent it is not very wide.
And one more thing worth saying out loud to them: almost nobody gets through these years with clear skin, including the people whose photographs suggest otherwise. The goal is calm and protected, not flawless.
