Most azelaic acid serum make my skin feel prickly or even a slight burning sensation so I was glad to find this, which has a lower percentage of azelaic acid but also combines CICA. This product does not irritate my sensitive skin and I still get some calming benefits. I use it in place of a toner after washing my face and before other products. It does seem to help calm my rosacea. Note that this is more soothing than moisturizing so you may still want some sort of barrier cream to use over it at night. It works great under my sunscreen during the day.
