I love this product!! After several trials, I concluded that it is the best. It gives the skin instant radiance and, by the time the 6 ampoules are used up, a clear, even tone, while other products usually need at least three months. The only vitamin that has helped me immediately... I give it 1 star less because this time I notice a change in the scent and I don't know what caused it. On the downside, it needs to be refrigerated and each ampoule keeps its active ingredients for 4-5 days, so you can't "save" by using less.

I have rosacea, not only did it not irritate me but it helped to eliminate the redness and dryness. Excellent product!

From the first time I used it, I saw a difference in my skin, and that's why I keep buying it repeatedly and will continue... I have done quite a bit of research on vitamin C, and this one has the ideal type of vitamin C and also the perfect combination of active ingredients that work perfectly together, which is immediately visible on the face. I have been using it for the last three years, and it has never irritated me. Also, I should note that I am prone to dark spots. In the summer, I had it with me in a cooler bag at the beach and applied it before my sunscreen when I was reapplying. I noticed a huge difference compared to when I used to apply just the sunscreen alone. It was as if I hadn't been exposed to the sun at all! I wouldn't trade it for anything else (I have tried others before settling on this one)
