Hi dermatologists! can i mix two facial toners (etude house wonder pore freshner and shiseido white lucent brightening balancing softener enriched) in the same bottle and use it as one toner?

Yes: If you like them, use them. I would not waste my money on either of them, much less on both.

Mix toners: hello ~ mixing toners in a bottle is not the same as 2 separate applications on the skin and there could be chemical reactions in the bottle that could effect the efficacy of function. Probably not a good to combine these 2 bottles. Also important, if the 2 bottles are separate it makes it easier to determine which one is causing problems wrt adverse reactions.thanks
