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.
Rebuilding a damaged skin barrier generally means stripping a routine back to the basics — a gentle cleanser, a plain moisturiser, and sun protection — while pausing exfoliants and strong actives. Most people notice some settling within a few weeks, though how long it takes varies a lot from one person to the next. How … Read more
Yes. Acne-prone skin needs sunscreen just as much as any other skin type — arguably more, since many acne treatments make skin more sensitive to UV light. The idea that sunscreen clogs pores or “suffocates” skin is largely outdated; the real issue is picking a formula that suits oily or breakout-prone skin. Why does acne-prone … Read more
Over-exfoliating wears down the outer layer of skin faster than it can rebuild itself. This weakens the skin barrier, leading to redness, tightness, stinging, peeling, and sometimes more breakouts rather than fewer, because irritated, compromised skin is more reactive and often produces more oil to compensate. What is actually happening to the skin when it’s … Read more
Yes, but not by much. The core steps — cleanse, treat, moisturise — stay the same morning and night. The real differences are usually just one thing: sunscreen in the morning, and sometimes a stronger active (like a retinoid) at night, because some ingredients break down in sunlight or make skin more sun-sensitive. Do mornings … Read more
Skin purging is a temporary increase in breakouts that can happen when a product speeds up skin cell turnover, pushing existing clogged material to the surface faster than usual. A bad reaction is different: it’s irritation or new breakouts caused by a product that doesn’t suit the skin, and it tends to keep getting worse … Read more
Yes — most acne-prone skin still benefits from a moisturiser, and skipping it can make things worse, not better. Oily or breakout-prone skin can still be dehydrated or barrier-stressed, especially once treatments like benzoyl peroxide or retinoids come into the picture. The right moisturiser supports skin rather than feeding acne. Why does oily skin need … Read more
For most people with acne-prone skin, twice a day is the amount that tends to work best — once in the morning and once at night, plus a rinse after heavy sweating. Washing more often than that usually strips the skin rather than helping it, and can end up making breakouts look worse, not better. … Read more
Patch testing means applying a small amount of a new product to a limited area of skin — often the inner forearm or behind the ear — and waiting a few days to see if it causes redness, itching, stinging or breakouts before using it on the face. It’s a low-cost way to catch a … Read more
Introducing one product at a time matters because it’s the only way to know what’s actually causing a change in your skin. Add three new things at once and, if something stings, breaks you out, or seems to help, there’s no way to tell which one did it. One at a time keeps the cause … Read more
Most skincare products need somewhere between four and twelve weeks of steady use before it’s fair to say whether they’re doing anything. Cleansers and moisturisers can show their hand faster — often one to two weeks. Actives that work on acne, like retinoids or BHA, generally need longer, and skin often looks a bit worse … Read more
