I used the whole box on a daily basis. I didn't see any difference, even on recent dark spots, which with other products I have used, would have disappeared in a week?

I have tried so many vitamin C serum products, from Medik, Hydrovit, Darphin, La Roche Posay. I always return to this one. It is the most effective, the most practical, with the best texture and the nicest scent.

For vitamin C and for the price, it is good... of course, I have tried another product from a different company at about the same price and my face was brighter. So the other product was more effective. It is okay. Based on its price, I would give it a 7 out of 10.

This is the second box I am buying. I am really very satisfied. Since the summer, I have seen a noticeable result in the lightening of the spots. I only use it at night. It has no fragrance, and sometimes I have felt a slight tingling during application, but nothing significant.

When I got them, I had some reservations because I didn't know the brand. I decided to try them due to single doses (so the vitamin C is definitely protected from oxidation), price, and reviews. In the end, I want to say that they are very good. After 2 weeks of use only in the morning, my face brightened and some spots that had appeared disappeared. Incredible for the price. I will buy it again. Be careful, it always needs sunscreen.

Amazing product, it brightens and cleanses the skin from discolorations and small blemishes. My skin is softer. I recommend it

It's pure silicone! It may have good vitamin C, but silicone, which is its main ingredient, ruins everything

Atopic, light-colored and mature skin with a tendency for severe eczema here (until now I only used Toleriane) and with the first application, the difference was noticeable to others. It significantly improved sunspots. I wouldn't use it on a permanent basis due to my sensitivity, but it didn't cause me any problems. I shone :)) It takes a little time to fully absorb. I will buy it again

I have already used 3 packages and I am extremely satisfied. Some days I feel slight tingling on the skin when applying it, but no other discomfort. The skin is clearly more radiant and improved in texture. I will definitely buy it again

Although I was very pleased with the convenience of the single doses, it did not work for me... very intense itching... and a peculiar smell in the evening and early in the morning before washing my face... I imagine it is "oxidation" obviously... despite applying it on a clean face only at night...

I have written before that it caused irritations, but maybe a less sensitive skin won't have a problem

It has a perfect feel and is just what you need before makeup. Always remember to apply sunscreen after 20 minutes. I will buy it again because it has a very practical packaging and the vitamin C does not oxidize.

Leaves the skin very soft and you feel a wonderful sensation! It absorbs immediately, has a nice scent, and the packaging is very practical.

The packaging with the single doses is very practical. They are effective and give a nice feeling to the skin and overall they create a nice effect because they are essentially silicone with ascorbic acid. For anyone who doesn't have a problem with applying silicone on their face every day, it's great.

I have dry skin at the age of 35+ and I can say that after trying many vitamin C serums, I ended up here...

For discolorations, systematic effort is needed, but with the first box, I saw them decrease. Definitely, it gives radiance to the skin.

And only being in capsules makes you feel like you're not wasting your money, vitamin C oxidizes in bottles. I'm on my second wheel, one every night, summer, and at least I didn't see my wrinkles getting worse. Perfect texture, I also apply moisturizer on top. I will never stop using it, in fact, I will try the retinol in winter

I recommend them without reservation as they do what they promise! Amazing product with targeted face glow and elimination of blemishes. Top choice and I consider them one of the best cosmetic purchases!

It is the third package I have purchased. Amazing product. I have issues with discoloration and it has truly covered me completely. It leaves no trace of oiliness and this is important for me as I have oily skin. The fact that it is a single-dose product makes it more convenient and also safer as it does not oxidize. The feeling on the skin is velvety. I apply it every morning after cleansing and before day cream. And of course, we don't forget the sunscreen (which is also enhanced with vitamin C).

I am very satisfied. It does the job and the difference is noticeable from the first days. I will definitely buy them again.

It is a product that should be applied at night for it to have results. I am very satisfied and have been using it for two years. I have seen a significant reduction in wrinkles (both the ones I had and the ones I developed during pregnancy) and brighter skin.

Unfortunately, I had a bad experience with this product. The ampoules were dehydrated and most of them were opened at the seam. The pharmacy where I bought them informed me that other customers had also reported the same problem and they replaced them with another vitamin C product. I will not buy them again because it is probably a manufacturing flaw in the outer casing.

Very good product. I noticed a difference in the texture of my skin and in the fading of my blemishes. Especially compared to other blemish-fighting cosmetics that I used to spend a lot of money on, it is superior.

The image I have after 10 days of use is very good. It moisturizes and makes the skin brighter. Also, a very good quality-price ratio.

I am satisfied with this specific product. I noticed a difference in my skin and I like the velvety feeling it leaves. I will buy it again!

It illuminates the skin in general and I have bought it several times because it contains ascorbic acid, which is the most studied form of vitamin C. I wear it every morning before the cream and sunscreen. The negative aspect is that when I apply it, it develops a strange smell, as if it is oxidizing.

It is the first product with vitamin C that I use and although I have no point of comparison, I am very satisfied. I use one ampoule every morning, after cleansing and before day cream/sunscreen. Day by day, my face becomes more radiant and healthy. I have no opinion on the fading of blemishes, as I do not have any on my skin. I like the velvety feeling it leaves. Makeup applies perfectly.

Very good ampoules. First of all, I have to say that they leave a wonderful feeling on the skin, like velvet!! Although I don't use them every day and only use them in combination with dermaroller treatment, I saw amazing results after a few applications, equivalent to a treatment against wrinkles in a beauty salon. (I have tried other products with vitamin C and didn't have the same results). They have become my best ally against wrinkles.
