When I first got this, I thought nothing of it. It's just another vitamin C. That's where I was wrong.▶ 2:31–2:35
Typically, vitamin C serums are kind of drying cuz they have to be acidic, but this one does not dry out my skin, it does not sensitize it.▶ 2:35–2:40
I can even use it when I'm using tretinoin and I do notice such a nice difference in my skin.▶ 2:41–2:46
It really just kind of refines my skin and brightens it in such a beautiful way.▶ 2:46–2:51
