I ordered this product because I am familiar with the Anua brand, their heart leaf toner went viral this past year or so (though I never tried it). Anywho, this is a Korean beauty / Asian beauty product, which I typically find to be more gentle and this doesn’t disappoint! I am a daily retinol user, so I have to be careful when it comes to exfoliants. I have been using this daily alongside .05% retinol and have not had any issues!! As well, I live at extremely high altitude and tend to have extremely dry skin as a result of that + the tretinoin, but I am able to use this toner without drying out my skin further.I am a fan of this toner, the price is what I would expect to say. I have only been using it for about a week, so it’s tough to say until I finish the bottle, but at present I think I will be repurchasing. I have used the Paula’s choice BHA toner in the past, and I do prefer the anua. Both toners primary active is salicylic acid.
