My New Holy Grail! ⟡
Size: 8.45 Fl Oz (Pack of 1)
Finally Azelaic Acid that don't break me out. I've tried US skincare and they are nothing but harsh to my skin. I've tried korean skin care before but I guess I wasn't buying the product that targets my skin concerns. Now that I'm giving korean skin care a second go, it did not disappoint! I can see my skin improving! ⟡

So glad I finally tried this totally worth it!
Size: 8.45 Fl Oz (Pack of 1), Size: 8.45 Fl Oz (Pack of 1)
I love Korean skincare and have been wanting to try Anua for a while, but I always found it a little on the pricier side. I was placing a Black Friday order and snagged this toner for $15, and I’m so glad I did! I originally wanted to try their azelaic acid serum, but since I already use a lot of serums, seeing it in toner form felt perfect — and it really is.
I’ve been using this morning and night, and my skin already looks brighter. I have a lot of acne scarring, and even in the short time I’ve been using this, I’ve noticed visible improvement. It’s super gentle, not harsh at all, and has a light, pleasant scent (which doesn’t seem like added fragrance).
My skin is extremely acne-prone, and this hasn’t broken me out whatsoever. If anything, it feels calming. So far I’ve truly enjoyed this product, and I definitely recommend it if you’re looking for something soothing that actually helps with texture, spots, and overall clarity!
