By Wishtrend Mandelic Acid Gentle Exfoliating Toner 150 mL

I've been using this Mandelic acid on my oily, acne-prone skin for several years. I usually buy it from the K-beauty retailer but needed some sooner and was able to get it from iHerb for a decent price. My skin has never looked as good as when I started using the majority of Korean skin care products.

I wanted to incorporate gentle acid into my skincare for gentle chemical peeling/exfoliation purposes. As a beginner, I find using this skin prep water as toner twice a week frequency works okay for my skin - no breakout, no stinging sensation. But of course do your research as to which serum would work out great with mandelic acid (the component of this item), just to make sure the effectiveness of your products don't cancel out each other, and if anything, works well if used combined together
