I use the serum for a few days and am quite satisfied with the result. The consistency was for some getting used to, because I've only used creams, but now it's okay. The smell does not please me, but as it passes quickly, it's not so bad. For me, the serum moved very quickly and initially stressed skin something (such as if you were a peeling facemask), but after a few days they had become accustomed to the care. The complexion has slightly refined, but huge changes I could not tell. However, I feel that my skin a bit "rich", ie until the evening it is fresh, which I like very well. The price is, in my view, already very high, since one still needs a day care. However, I like the result, so I'll treat myself now and then the serum.
