It's the first time I've tried this ampoule and I love it. I have combination skin that is drier than anything else, and this helps me a lot with that, I use it every night I'm not sure if I can use it during the day but for the night it's perfect, the next day the skin looks hydrated and glowy. I am going to continue using this for months, if it has given me results in a short time, in the long term they must be incredible.
