Generally satisfied, I did break the first two ampoules until I got the hang of it. Don't press too hard on the plastic tip because with pressure the ampoule gets pushed out and breaks. It feels very nice, yes it's a serum but it's not oil. The cream applies perfectly and locks in moisture. The price is good, and the big plus is that the ampoule lasts for up to 4 applications so the vitc doesn't oxidize. Now for results: what can I say, I am 53, I have good skin and I follow a skincare routine, miracles are not expected.

Very good. Especially for mature skin it gives the shine it needs. Of course, the results do not last, they are only for as long as you use it.

It is a very unique product. My skin has become like a baby's, elastic and radiant (without excessive oiliness), but it does nothing for my dry skin. I started combining it with a moisturizer and I can truly say that it is almost like magic how effective it is for the health of the skin.

If you don't have dry skin, give it a try! Each ampoule is enough for 2 applications, but you need to close it with the cap that the packaging has, otherwise the vitamin C inside oxidizes.
