I got these two toners and tried layering the Isntree toner on top of the numbuzin no 1 toner but it stung really bad.
I’ve layered the isntree HA toner with the Cosrx 6 peptide serum & I was fine. I use the numbuzin no 1 toner every morning & I have no issues but both of them together really irritated my skin.
I guess that’s something you guys should watch out for if you have both of them and are thinking of layering them.
