No.5 Vitamin Concentrated Serum
No.5 Vitamin Concentrated Serum
Sold as a vitamin serum, but the list opens with lingonberry extract, niacinamide and tranexamic acid, and the ascorbic acid and its derivatives sit a long way down it. Read it as a tone blend with vitamin C in it rather than as a vitamin C serum. It still oxidises in the bottle, which is why 30 ml is the right size and finishing it is the point.

Listed in INCI, the standard naming used on every cosmetic sold in the EU. It is the same in every language.
The pack is the authoritative list. Brands reformulate without announcing it, and the batch you receive may not match this page - so if you react to something, check the pack itself before you use it.
We could only find the list this brand publishes for another market. The European pack may differ, and we have not been able to confirm either way.
