Here's what our community thinks
The Ordinary Azelaic Acid Suspension 10% 17 ingredients
It’s a great starter product with azelic acid.
The price is relatively cheap, the tube will last you long time and it delivers what it should - azelic acid.
However, despite people’s suggestions here I personally would not use it as last step. It does not say it on their homepage but azelic acid has usually low ph. Thus adding it as last step might cause damaged skin barrier on a long run! Show more
Hate
I have rosacea and perioral dermatitis so I thought this would heal my skin but I HATE it. It’s silicone based so it dries matte and you can’t apply sunscreen or any makeup on top. You also can’t reapply because it’ll start pilling. Don’t even think about touching your face after putting this on because it’ll pill. It also stings really bad which is the opposite of what you need for rosacea Show more
