Small batch · Labelled in full
Skincare with the numbers printed on it.
Most brands tell you an ingredient is inside. We tell you how much, at what pH, and in what form — because a serum at 2% and a serum at 15% are not the same product with different packaging.

Where most people begin
The four that do the most work
Four steps, in this order
A routine is a sequence, not a shelf
Order changes what absorbs. Do these four and stop — most people who react badly to skincare are using too many actives at once, not the wrong ones.
01 · Step one
Cleanse
Take the day off without taking the barrier with it. A gel in the morning, a balm at night if you wore sunscreen.
02 · Step two
Treat
One active at a time, at a concentration we print. Vitamin C in the morning or a retinoid at night — rarely both at once.
03 · Step three
Hydrate
Water held where it is useful. Humectant on damp skin, then something occlusive to keep it there.
04 · Step four
Protect
Two fingers’ length, every morning. The single most effective thing in this entire shop, and the least exciting.
What we will not do
Three commitments, all of them checkable
100%
INCI on the carton
The full ingredient list in descending order, in the box, in the size the regulator requires — not hidden behind a QR code.
0
Fragrance, by default
The clinical range carries no fragrance and no essential oils. Where a scent exists it comes from the botanical itself and is declared.

Days to send it back
Opened, half used, disliked. We refund it. A formulation you cannot test is a formulation you cannot judge.

Lab notes
Three numbers worth understanding
If a brand will not tell you the concentration, assume it is below the studied range.
15%
L-Ascorbic acid
The most studied form of vitamin C. Unstable in water, which is why the bottle also carries ferulic acid and vitamin E — and why it is in amber glass.
0.06%
Retinaldehyde
One conversion step from retinoic acid, where retinol needs two. Lower dose, comparable result, shorter adjustment. Encapsulated so it arrives where it is needed.
3:1:1
Ceramide ratio
Ceramides NP, AP and EOP in the proportion found in healthy skin, with cholesterol and fatty acids. The ratio is the point; the percentage is not.
Our position
A product that cannot tell you its own concentration is asking you to trust instead of telling you anything.

Not sure where to start?
The Full Ritual is the four steps above at the sizes that matter, with a card that says what order and how much. It is the cheapest way to stop guessing, and the only thing we recommend to someone buying their first proper routine.
