Skincare ingredients are most useful when you can tell what they do, what they don't, and where the evidence stops. This is a short, working primer — written by the same people who formulate the product, with the same vocabulary we use in the lab.
Why this ingredient, and not another
The most-asked question is rarely "does it work" — that's been settled in literature for years — but "for whom, at what dose, and under what conditions." We'll walk through each.
- Mechanism — what the molecule actually does at the cellular level.
- Dose — the percentage range that's been studied, not just the one on the bottle.
- Combinations — what to layer with, what to keep apart.
- Patients — who tends to see results, and how long it takes.
What the studies say
A consistent body of work supports a daily, twice-daily routine at the dose used in our formula. We've linked the most useful papers in the citations below — and we re-read them yearly so this page stays current.
"The most effective formula is the one a person will actually use, for long enough to see a result. Everything else is a detail."
— Dr. Anaïs L., Head of Formulation
Working with this in a routine
We recommend a four-week introduction window. Use every other night for the first two weeks; daily thereafter. If you stack it with another active, separate them by 10 minutes or alternate AM and PM.
