Why you are still breaking out

What actually causes a spot

Four things have to line up, and every effective treatment interrupts at least one of them.

• The lining of the pore sheds skin cells too fast and they stick together instead of clearing.
• Oil production increases, usually because androgens told it to, and feeds the plug.
• C. acnes bacteria, which live on everyone, multiply in that oxygen-free plug.
• The immune system reacts to the bacteria, and that inflammation is the red, sore, swollen part.

Notice what is not on that list. Dirt is not on it. Acne is not a hygiene problem, and the pore is blocked from the inside where no cleanser reaches. This is why scrubbing harder achieves nothing except a damaged barrier, and why people who wash their face four times a day still break out.

Why it is worse in your twenties and thirties than it was at school

Adult acne is mostly hormonal. Androgens increase oil production, and the fluctuation matters more than the absolute level, which is why breakouts arrive in the week before a period and clear afterwards. It concentrates along the jawline, chin and neck rather than the forehead, and it tends to be deeper, sorer and slower than teenage acne.

That pattern is worth recognising because it changes what works. Hormonal acne responds poorly to surface treatments alone and well to things that either reduce oil or speed up cell turnover inside the pore. It also responds to prescription options, and there is no prize for struggling through years of drugstore products first.

Which ingredient treats which problem

Most people fail here by using the wrong active for the kind of acne they have, then concluding nothing works.

Higher strength is not better. Benzoyl peroxide at 2.5% works as well as 10% with a fraction of the irritation, and that is one of the better-replicated findings in dermatology. Adapalene at 0.1% is the standard, and going higher mostly buys you peeling.

Use one new active at a time. Layering three at once is the most common self-inflicted route to a damaged barrier, and when it does go wrong you have no idea which one to blame.

The part nobody wants to hear about timelines

A spot you can see today started forming under the skin two to three weeks ago. Nothing you apply tonight changes what is already in the pipeline, which is why week one of a new routine so often looks like failure.

Six to eight weeks is the minimum honest window for judging an acne treatment, and twelve is better. Retinoids in particular get worse before they get better: the purge is real, it happens because turnover has sped up and everything already forming is arriving at once, and it typically settles by week six. If it is still worsening at week ten, that is not a purge, that is irritation.

Stopping at week three because it has not worked is the single most common reason people cycle through products for years without resolving anything.

What makes it worse

• Over-cleansing. Twice a day, gently. Stripped skin compensates with more oil.
• Physical scrubs and cleansing brushes on inflamed skin. They spread bacteria and damage the barrier.
• Picking. It turns a spot that would have healed in five days into a mark that lasts five months.
• Skipping moisturiser because your skin is oily. Dehydrated skin produces more oil, not less.
• Skipping sunscreen. Every active here makes you more sun-sensitive, and sun makes the marks left behind far darker and far more permanent.

If your skin is oily and dehydrated at the same time, that is not a contradiction. It is usually the result of a routine that has been stripping it.

When to see a doctor rather than buy something

Cystic acne, the deep painful lumps that never come to a head, does not respond to anything on a shelf and scars if left. Acne that is scarring, acne that has not improved after three months of consistent over-the-counter treatment, and acne that is genuinely affecting how you feel about going out are all straightforward reasons to see a GP or dermatologist.

Prescription options are effective and boring: topical retinoids at higher strengths, topical antibiotics combined with benzoyl peroxide, hormonal treatment including some combined pills and spironolactone, and isotretinoin for severe cases. People routinely spend more over two years of guessing than a course of treatment would have cost.
