I knew it was 30ml but it is still a lot smaller than I expected given the size of other products of a similar volume. I have always loved a dropper design since it is much more sanitary. I think this ampoule would be good for a winter skincare routine given its thickness. It's definitely not something I would use in the summer. Good ingredients, not very flashy with a bunch of random stuff. Centella is first and foremost, which is appreciated.
