Before using it, I used the collagen bomb amoule from the same brand. It was pretty hydrating and seemed to last a long time, so I decided to try another ampule from Badskin. It is also as good as the collagen one. The texture is a little different, I think this one is absorbed more easily than the collagen ampoule. It also moisturizes my skin a lot and gives me a brighter complexion. It has a light smell but does not feel heavy. It also did not irritate my skin or gave me breakouts.
