Clear, honest information about acne, skin and what actually helps
Written by careful researchers who read the studies. We are not dermatologists — and we say so on every page.
Acne mechanica is breakouts caused by friction, heat, and pressure against skin, rather than by oil and bacteria alone. Straps, pads, helmets, and tight clothing rub or trap heat against the skin. That irritation blocks pores and triggers bumps in the exact spots where the gear sits. The name gives it away. “Mechanica” refers to … Read more
Maskne is the informal name for breakouts and irritation that show up where a mask sits on the face — usually the cheeks, chin, jawline and around the nose. It happens because fabric rubs the skin, breath and sweat get trapped underneath, and that warm, damp environment disrupts the skin’s normal balance. What exactly is … Read more
No. Oily skin means the skin produces more sebum than average; acne-prone skin means it tends to form clogged pores and breakouts. Most people with acne-prone skin do have oily skin, but plenty of people with oily skin never break out, and some people with dry or normal skin still get acne. The confusion is … Read more
Skin makes oil, called sebum, because it needs a way to stay flexible, waterproof and protected from the outside world. Without it, skin would dry out, crack and lose its barrier faster. Oil is not a design flaw — it is a basic maintenance system that everyone’s skin runs, just at different speeds. What is … Read more
Yes, acne does tend to run in families. If a parent had moderate to severe acne, their children have a noticeably higher chance of developing it too. But genetics is only one piece of the picture — it sets a tendency, not a guarantee, and plenty of people with no family history still get breakouts. … Read more
A closed comedone is a clogged pore that stays sealed under the surface of the skin, so it shows up as a small, skin-coloured or slightly raised bump rather than a dark dot. It forms slowly, sits deep, and often doesn’t respond to quick or one-off fixes — which is why it tends to hang … Read more
Adult acne usually comes down to a mix of hormone fluctuation, genetics, and how an individual’s skin reacts to oil and inflammation — the same basic mechanics as teenage acne, just running on a different set of triggers. It is common, not a sign of poor hygiene or a skincare routine done wrong, and it … Read more
Acne forms in and around hair follicles when oil, dead skin cells and bacteria combine to block a pore, producing blackheads, whiteheads, or inflamed red bumps. Many other bumpy skin conditions look similar at a glance but form through completely different processes, which is why so many bumps get mistakenly called acne. Telling them apart … Read more
Acne often looks worse before it improves because some treatments speed up how fast clogged pores surface, pushing existing blockages out faster than usual. This can look like a new wave of breakouts, but it is usually the product working through backlog rather than creating fresh damage. Irritation from a product reacting badly is a … Read more
The skin barrier is the outermost layer of skin, made mostly of dead skin cells and fats, that keeps water in and irritants, bacteria and pollution out. When it’s working well, skin feels comfortable. When it’s damaged, skin can sting, look red, feel tight, and become more reactive to products it usually tolerated fine. It’s … Read more
