Q10 Etos Vitamin C Booster

The serum smells great, according to the instructions for use, you only have to add 2 drops to your cream, preferably natural in combination with their own q10 line. I apply this on my face and then apply a cream. So I also use more like a few drops. The serum lubricates finely and absorbs well. In my opinion, it has given my face a little more glow and reduced blemishes. But I wonder what the concentration of the vitamin c is, it is in a glass bottle so that gives me the impression that the vitamin c is protected from light. The jar is not airtight, so that the vitamin could be lost faster. I also notice that I use vit with other brands. C had a tingling sensation on my skin and that there was a yellowish oxidation on my face, whether that is correct is still to be doubted.. in short, I think it is a nice serum but doubt about the concentration and effect of the vitamin c itself.

The name is confusing because the product belongs to the q10 line, but there is no q10 in this product. It is a VitC serum. Potty looks happy because of that yellow one. Glass isn't transparent, so at some point it's hard to see how much product is still in it. Serum is milky white, scented. I got it for my hands. They also come out in the sun a lot, and are cleaned 100x a day. I'm also trying to use SPF, but I thought it could be added to it. On my hands, it also has to be less cosmetically elegant than on my face, so I prefer to find a cheaper product. This serum spreads well, and also fits well among other products. Is hydrating, but only if you smear something over it. But that was about it. For many products, you have to use them for at least 4 weeks before you see results, but this product was also run out approximately after 1 month. Or even earlier. I probably used more than what you would use on the face. My hands look okay, but not great either. Etos products are often on sale, and in terms of price, it is not too bad. But in the meantime, I'm using another VitC product for my hands.
