I'm liking this Vitamin C so far. I've only been using it a few weeks so it's still a little early to see results, but it hasn't broken me out or stung like every other vitamin c'I've used in the past. In fact, this is the first vitamin c I didn't give up on fairly quickly for one reason or another. Most vitamin c's either break me out, sting even after 2 weeks, or are simply too oily/shiny for me to use long term. This does have a bit of that vitamin c smell, but isn't as strong as some I've tried. I will say that upon application I do get a little flushing/redness, but it dies down fairly quickly. Benton is such an underrated brand. None of the western YouTubers seem to talk about them (Kelly Driscoll not withstanding). I really don't get it. Their products work so much better for me than Numbuzin, haruharu, Beauty of Joeseon, etc that most reviewers gush over.
