From bare skin to a complete, effective routine — built on skin cycling, paced by your skin. Starter and Beginner: the two tiers that take you from nothing to a routine that works.
Start wherever you are. A total beginner walks the whole way; if you already use a few actives, find your tier and drop in. You only level up when your skin says you're ready — never on a deadline.
This is a standardised starting point — a proven framework built to be shaped around your own skin as you go, with my guidance and the rest of the Skin School content. A few principles make it work:
This isn't personal medical advice. If you're pregnant or breastfeeding, skip retinoids and check with your doctor about the rest. If you have a skin condition such as rosacea, eczema or melasma, or you use prescription skincare or medication that affects your skin, treat this as a framework to adapt with professional guidance. Always patch test a new active, and if something stings, burns or stays red — ease off and go slower.
Prep. Cleanse, moisturise, SPF + B/HA serum. No actives.
Weekly rhythm begins. Acid, then low retinal, then vitamin C.
Strengths step up — idebenone, PDRN, repair nights — to Master.
By the end of this volume you'll have a complete, effective routine you can run for the long term. Volume Two · Progression is the optional climb beyond it — only when your skin is ready.
This is the bit most people get wrong. Don't pile products onto wet skin. Apply your active and wait until it's fully dry before anything goes over it — that protects how it works. Then your B/HA serum, then a mist of thermal spray over it (the mist gives it the water it needs to draw in, instead of pulling it from deeper in your skin), let that settle, and only then seal with moisturiser.
You'll learn the thermal-spray step in Starter, before any actives — so by the time the actives arrive, the rhythm is already second nature. And because each active goes on dry skin, the steps that follow don't need repeating: once a layer is dry, the next simply goes on top.
Two weeks to prep — build a calm barrier and learn the rhythm, including the thermal-spray step, before any actives. No weekly pattern yet: every night is the same.
Why start with nothingA calm, intact barrier is what lets every active later land without drama. Two weeks of just cleanse–serum–moisturise–SPF builds the habit and the foundation — skip it and actives have nothing stable to work on. Your moisturiser is the one thing that shifts between day and night: a lighter emollient under SPF in the morning, a richer ceramide cream to repair overnight. For that night cream the repair comes from the whole barrier trio — look for ceramides paired with cholesterol and fatty acids, ideally in a physiological ~3:1:1 ratio, which rebuilds the barrier far better than ceramides alone.
the routine is an automatic daily habit, your skin is calm and comfortable, and the order feels natural. Around 2 weeks.
Your weekly rhythm starts — but the actives arrive one at a time. The acid night comes first, the retinoid joins (one night, then two) about two weeks later, and only then does vitamin C build in the morning. A hydrating toner joins your mornings now, too.
Your week once fully eased in — hydrating toner every morning, vitamin C daily by week 13. Acid Monday, retinal Wednesday & Friday, recovery between.
Why one at a timeIf you introduce the acid, the retinoid and vitamin C all at once and your skin reacts, you'll have no idea which one did it. Spacing them out means every active gets a clean trial — and your barrier is never hit with two new things at the same time.
Use a leave-on acid — a toner or serum you apply and leave on. Start gentle and build slowly. A PHA is the kindest — it works on the surface, exfoliates slowly, and hydrates at the same time, so it's the safest place to begin. Next gentlest are lactic and mandelic — mild AHAs (the gentle end of the same family as the stronger glycolic). Save glycolic (the strong AHA) and BHA for once your skin is well-established — BHA suits oily or congested skin in particular. The acid only steps up in strength much later, in Volume Two.
Bare skin is the deepest delivery — earnedOn clean, dry skin an active works most directly: retinal, like vitamin C and acids, can go straight onto bone-dry skin after cleansing for the strongest effect. But the most direct route is also the most likely to irritate if any sensitivity is there.
So while you're building tolerance, you cushion the retinal — a thin layer of moisturiser before it (the buffer), or moisturiser before and after (the sandwich). The moisturiser is the real cushion: its richer texture is what slows the retinal down. A watery toner won't do that job — hydration actually speeds an active in, not down — which is why retinoid nights stay toner-free for now and lean on the buffer instead. Use it freely; you'll wean off it in Volume Two as your skin learns to take the retinal bare. And if even a buffered low-strength retinal is too much for your skin, bakuchiol is a gentler, non-retinoid alternative that gives similar results — there's more on it in the Buffer card.
One active at a time — watch the evening fill in, then vitamin C ease into the mornings. Same dot language as your weekly map; only what changes each step is shown.
Vitamin C starts on a few spaced mornings and builds to every morning by week 13 — then the week holds while it all settles in.
the weekly rhythm feels comfortable at low strengths, vitamin C is daily and well tolerated, and your barrier stays calm — no lingering redness or flaking the morning after an active. Usually weeks 12–14. Intermediate is where Volume Two picks up.
By here you have a real, working routine: a calm barrier, one weekly acid night, a low retinal twice a week, and vitamin C every morning. This is a brilliant place to be — many people happily run a routine at this level for the long term.
When your skin is fully settled and you want to go further, Volume Two · Progression takes you up through Intermediate and Advanced, the same careful way:
It's the routine I run myself. We'll get you there only when your skin says it's ready. Take Volume Two when you're ready to climb.
One serious active per night, never a retinoid and acid together. Let each layer dry before the next — active, then your B/HA serum, then a mist of thermal spray over it, then the moisturiser seals; once a layer is dry, the next just goes on top. One leave-on acid night a week; gentle daily exfoliation comes later, in Volume Two. Retinoid nights stay toner-free for now and lean on a moisturiser buffer while you build tolerance. Double cleanse every night, since SPF goes on every morning. Strengths only ever rise through a gradual change-over, never two actives at once. And above all — this is a standardised starting point to adapt to your own skin. The week numbers are a guide; the graduation gates, and your skin, are the rule.
