I have used this product in the past and it's really great at controlling redness. After a recent flare up it reminded me of this fab product. It's now going to be a constant going forward.

This is not the only non Kbeauty skincare I use, it makes my skin the freshest and clearest without significant irritation. I can tell its effect after each use!

Love it! I have rosacea and can be acne prone and this really is one of my holy grail products. 

I've tried my fair shair of azelaic acid products, nothing comes close to this one. Helps with breakouts, not particularly with PIE (mine is very stubborn though, only laser helps), but it's the best product for congestion. Not sure if that's the salicylic acid in the formula, but something in that product works. Pricey but a holy grail.

I keep repurchasing because it somehow just keeps all my breakouts away. A bit pricey but the ingredients and the effect I get from it is more then worth it! It has no added fragrance so it does have a particular smell but I just use a nice smelling moisturizer over it since I haven't found a better azelaic acid product on the market.
