reliable mild exfoliating toner for everyday
My favorite toner that helps evenly exfoliates the flakey dead skin. It helps with minimizing acne from clogged skin buildups like dead skin and oils. I find glycolic acid too harsh even when using it once a week so this is perfect and it has no added fragrances. I tend to switch up my skincare regimen based on what good deals there are but I'm on my 5th big bottle of this stuff and it's a good deal for this size. I tried out other skin toners like roundlab dokdo, tiam b5 but my oily skin prefers this more.

My favorite toner + lasts a long time!
I have tried TONS of toners. This one beats all of the other toners by far (even the viral milky toners)!
This toner absorbs quickly into the skin. This really calms down any redness or irritation I have. I use it both in my night routine and my morning routine before any of my other skincare. One bottle also goes a LONG way! I am on MONTH 7 of 2x daily use, and I still have at least a months worth left! I apply the toner directly into my hand and pat on my face (some people use cotton pads but I feel like it wastes a little bit of product).
