Rose Hyaluronic Serum,
Line by Line
Seven things go into this bottle. On the label they become more than twenty names — and for the first time in this series, not all of them are natural. Here is every one, and why we made that trade.
Last time we took the toner apart and found six honest ingredients. The serum is where it gets more interesting, and more complicated, because a serum is asked to do more than a toner — and doing more meant, in a few places, reaching past what nature offers. This is the article where we tell you exactly where, and exactly how much.
Here is the whole formula, in the order it is blended:
Seven ingredients. The label shows more than twenty names, and the gap between those two numbers is the most useful thing we can teach you about reading any ingredient list.
1 · Rosa Damascena Flower Hydrosol the base
The serum is built on the same Bulgarian rose hydrosol as the toner — and there is even more of it here, ninety-five percent. If you read the toner article, the story is the same: this is the fragrant water from a rose-otto distillation in Bulgaria, and the otto itself is present only as the trace the hydrosol carries. The rose is the constant thread through everything we make. What changes from product to product is what we add to it.
2–4 · The three that make it a serum Niacinamide · Hyaluronic Acid · peptides
A toner readies the skin; a serum is where the active ingredients go. Ours has three, each at a small, deliberate dose.
Hyaluronic acid, one percent, is the humectant the serum is named for — a high-molecular-weight grade that holds water at the surface. Niacinamide, a form of vitamin B3, is one of the most-studied ingredients in skincare, and it is here at one percent. And Matrixyl 3000 is a peptide complex — the ingredient responsible for most of that long label, which brings us to the honest lesson.
When you buy an active like Matrixyl, you are not buying a pure powder. The two working peptides — Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 — arrive already dissolved in a carrier of water, glycerin, butylene glycol, a stabiliser and a solubiliser, because that is the only way they stay usable in a formula. Every part of that carrier must, by law, be named on the label. So one ingredient you chose becomes eight or nine names on the box. Next time an ingredient list looks alarmingly long, this is usually why: it is not more stuff, it is one active honestly unpacked.
5–6 · Green tea and vitamin B5 each a supporting note
Green tea extract brings antioxidant polyphenols and, as in the toner, arrives in a glycerin base — which is why Glycerin sits high on the label without appearing on its own line in the recipe. Panthenol, vitamin B5, is a humectant and conditioning agent at half a percent. Both are supporting notes, dosed as supporting notes, and we would rather show you the small honest number than imply a heroic one.
7 · Glyceryl Caprylate — the preservative, named protection
As with the toner, we will name the preservative rather than hide it. Here it is Glyceryl Caprylate, a coconut-derived ingredient that does double duty as a humectant and a preservative, at one percent. A water-based serum needs protecting, and we would rather tell you what does the protecting than sell you an unpreserved bottle with a dangerous shelf life.
The honest part: not entirely natural
The toner is one hundred percent natural. This serum is ninety-seven and a half percent natural, and ninety-six percent certified organic. We could round that up in our heads and call it “natural.” We are not going to.
The part that is not naturally derived is the niacinamide, the panthenol, and the synthetic peptides in the Matrixyl complex. We chose them on purpose. A fully natural serum is easy to make and easy to market; it is harder to make one that also contains the specific, well-characterised actives that a serum is supposed to earn its price with. We decided we would rather be a serum that works as a serum and name the exceptions, than one that keeps a rounder claim and quietly does less. If a fully natural formula matters more to you than the actives, the toner — genuinely natural throughout — is the honest place to look.
The five names, again
At the very end of the label sit the same five you met in the toner: Citronellol, Geraniol, Farnesol, Linalool, Eugenol. They are the naturally occurring aromatic compounds of rose, carried in with the hydrosol, not added. Because this is The Full List, here is their scale, and it is the same as the toner's: together the five come to less than 0.0500% of the formula. As before, that total is drawn from the figures for the rose hydrosol as it arrives rather than from an assay of the finished serum, and the supplier describes them as typical values. We would rather give an honest order of magnitude than a false decimal.
The same honest condition applies. If your skin reacts to rose or to essential-oil aromatics, this serum carries them, and you should patch test on the inner arm before your face. Small is not the same as none.
The label on the back of the bottle prints all of this because it has to. We printed it here, including the awkward part, because a series called The Full List has to mean the full list — including the parts that are less flattering to say out loud.
Later in this series: what we leave out of everything, and why “free-from” is usually marketing.
