"The Peter Thomas Roth Potency Vitamin C Power Serum isn't actually my personal favorite vitamin C, I still think something like Geek and Gorgeous is a very good option, but I get that some people might be looking for a vitamin C product in this sale, and this is a pretty good derivative vitamin C serum, it is THD ascorbate, which is very hard if not impossible to find in K-beauty. This is still expensive, I think that's the price to pay for it, no reason to pay full price."
