RAUPYAM LABS
Science
What we can show, rather than what we can claim. Ingredient evidence, and the records behind the materials we buy.
Most skincare brands ask you to trust a number on a label. That number usually comes straight off a supplier's certificate of analysis, and in most cases nobody at the brand has ever measured it. We decided that before we sell anything, we would learn to measure our own materials — properly, on our own instruments, and in public.
These pages are that work. Raw Material Filesrecord what we ordered, what arrived, what the certificate claimed, and what we were actually able to verify — including the times the two did not match. Open Lab records how we measure: the analytical methods, the wavelengths, the decisions, and the mistakes we made getting there. Publications holds the work that went far enough to write up as a paper and submit for review. The ingredient pages summarise what the published evidence says about the actives we use, and how we have chosen to use them.
None of it is a claim about a product. It is a record of work, published as we do it, because a result you cannot inspect is only a claim wearing a lab coat. When products ship, batch reports will record what is actually in the bottle.
Papers and preprints
·In progress·One paper under peer reviewPublications
Work that went far enough to write up properly and send out for review. Our first paper is with a metrology journal.
Ongoing series
·In progress·Two method notesOpen Lab
We publish our analytical work — how we measure what we make, and why. Open, because a result you cannot inspect is only a claim.
