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!

Another Amazing Product from SKIN1004
I own at least 4 products from SKIN1004, because they really are a great skin care brand to invest in with. For reference, I have dry sensitive skin, I am prone to dark spots, some acne, dry patches and bigger pores. I have always had bad experiences with toner's so I was really hoping this would work for me. And it did more than that! I do believe my acne has gone down since using this, and to really test it out I finished the bottle after 5 and half months of daily morning and nighttime use. My skin feels smoother and bit brighter, more than anything it really keeps your skin clean without drying it out. It doesn't have a particular smell, the consistency is like water, and when you apply it is a bit tacky but no worries once it dries down completely, that goes away. This toner could be used by all skin types in my opinion. I will be trying their brightening toner soon, which I am even more excited about! Would repurchase.
