It was my first time using a snail essence. This product is pretty underwhelming at first, but I found that the more I use it, the more I like it. It didn't make my face break out, and served as a good base layer underneath moisturizer. It was also useful for relieving itchiness when I had horrible, huge itchy bug bites. The 100ml size is very handy--I've had the same bottle for months and there is still a lot left.
