Have been allowed to test this vitamin C booster. I really like the packaging to see. The booster is in a glass bottle with a pipette that I like. It is a rather thin composition which makes it pleasant to distribute. Fragrance is very subtle, it smells like citrus. Have used the booster for two weeks every morning and evening in my routine. My skin is pretty dry and I suffer from red spots on my cheeks and forehead. See that the redness has become a little less hope after longer use it gets even less. I like the quality at this price quite well. For now I'm sure to keep using it and visit the@ vitaminstore for the day and night cream as well. A stay for now.

For a few weeks I have been using a vitamin c booster of the every morning @Vitaminstore. Honestly, I have a little doubt if this product really does what my skin does. At least I haven't noticed any of it (28 years). My sixty mother-in-law certainly does what to do for her skin! Her face feels a little tighter since she used the booster;) However, I find the idea of spreading vitamin c on your skin interesting and will certainly continue with it. Not sure if I will buy this serum again, but it is a budget proof variant 👏🏻 It feels a bit like a thin gel substance (tends to water), easy to lubricate and absorbs quickly. Feels great on my skin. It smells like nothing! Convenient to apply with a pipette.

Last I receive this product from the @Vitaminstore to test, very nice! As I wrote back then, I wouldn't buy this product that fast myself. However, I was very curious and had a lot of questions. In the meantime, I have used the product for about 2 weeks and did some research, so here's my review. What I was wondering right away when I received the product is how you use it. Daily? Before or after using cream? The package says that you need to clean your face first and then apply 4-6 drops of booster. If necessary, you can mix the booster with your cream. I used the booster both morning and evening to apply my cream. The product absorbs quickly, so this was fine to do. What I was wondering is why I would use this product. According to Vitaminstore, “it reduces visible signs of ageing and helps to fade existing wrinkles and lines”. Okay, since I'm almost 30 and I'm starting to get a few lines, this sounded attractive... However, I wanted to know more about this and went on research. I always like dermatologist Jetske Ultee's blog for background information. So I searched her blog for information about vitamin C in skin care. I found the following: Vitamin C really improves the skin. It stimulates collagen production and can reduce acne and pigment spots. It is also an antioxidant that can limit UV damage. All sounds great! But, now it comes, there are a number of conditions: - Vitamin C only works in high concentrations of at least 4% - Vitamin C works best in other antioxidants, such as vitamin E - Vitamin C is very unstable and can withstand moisture, light and oxygen very badly. This oxidizes vitamin C and makes it less effective. The Vitamin C Booster does not contain pure vitamin C, but certain fruit and plant extracts that would be rich in vitamin C. I don't really think it achieves the high concentration of at least 4% vitamin C. And even if this amount was achieved, the vitamin C would oxidize by getting into contact with light (through the glass bottle), oxygen (through the pipette) and moisture (because the bottle is in my bathroom) and no longer work. Honestly, after 2 weeks of testing, I do feel like the product is not doing anything. It feels nice to smear on your face, but I don't notice any difference on my skin. I am going to give away the product and no longer use it myself. All in all I wouldn't recommend this product, a waste of money I would say. Prefer to spend your money on products that have proven to have good effects on your skin;)
