Four long years of struggling with horrific nodular acne… four long years, thousands spent on prescriptions, supplements, and makeup… and all I had to do was get my hands on THIS witchcraft?? Come on. It's been FIVE DAYS and it has absolutely transformed my face… I am GIDDY!!! But also so sad I'm just discovering this now! Do yourself a favour, do not hesitate…. Just buy it and thank yourself when you see your face GLOW after a single night of using this magic.

I was looking for an azelaic acid that would be gentle on my skin (as I have both seb-derm and rosacea), and this has been great! I'm still finding the right mix of products to give me the skin I want, and this has been helpful for texture issues specifically.

It clearing my skin up so good, reducing my redness and unclogging my pores.

reduced redness and a bit of my discolouration. Needless to say it was so noticeable that my friends were surprised from how my face appeared less red than usual!

I've been buying this the past 4 years. My skin loves it

My husband's doctor recommended this for his face and he really likes the results. His face has cleared up and not irritated like it was. He has a skin condition and his chemo treatments was making it worse.

I like this serum a lot and have gone through multiple bottles of it. Since they use glass packaging, they should provide return labels so you can return the bottles and get a discount on future purchases. It is disappointing of Naturium to take 0 initiative about this.

Didn't work well for me. I experienced a ton of purging and didn't see a difference afterwards. I used this for several months.

I have only used the product a couple times so I cannot speak on its efficacy yet. However, it pills. A lot. I recommend only applying at night unless you want to look like a shedding snake.
