Skip it if you already own something similar: it's a solid, honest basic rather than a must-have upgrade.

The formula, drawn

Every ingredient in label order, coloured by the job it does here.

7 of the 10 sit above the 1% line. The other 3, hatched, are each under 1%. Widths show the ORDER on the label and nothing else: the label never discloses amounts, so we never draw them.

How to use it

Morning and/or night, after your thinner water-based steps and before heavier creams.

Where it acts

The same cross-section as our 500 dalton page, with this formula's actives on the layer each one works on. Depth is the anatomy's, never an ingredient's.

3 of this product's actives have a layer we can defend. 1 did not, so it is not on the diagram: no source and no honest derivation means no dot.

Against the average serum

HydrationBarrier repairBrighteningOil-controlAnti-aging
This productMedian serum (27 in catalogue)

It scores lower than the median serum on brightening.

On hydration, barrier repair, oil control and anti-aging it is level with the median, so that is not what sets it apart.

A median, not an average: one unusual formula should not move the middle. The numbers are the same 0 to 10 reads the comparison pages use.

The full ingredients list, decoded

Every ingredient on the label, in the order it appears (highest amount first). We link the 8 our library knows, name what each one does, and flag anything that can irritate or clog. The rest we leave plain, nothing is hidden.

  8. roughly the 1% lineThe rules only require descending order above 1%. From Carbomer down, these 3 can be listed in any order the brand likes, so position stops telling you anything.
  9. CarbomerThickener
  10. Beta-GlucanHumectant
  11. Sodium PolyacrylateThickener

Worth knowing: Beta-Glucan sits below that line. It is in there, and the label does not tell you how much. That is not the same as saying it is too little to matter.
