Best Skin cleanser
Best ever. Deep cleans pore and I can see makeup melting off the face once you wash with this. Post results: Super clean soft skin, my face shines. Been using only for 2 weeks now, so cannot comment on Pore size reduction.
Extra sensitive eczema skin approved.

Nice products with positive results
I bought Anua toner, trio, and moisturizer. I am in love with these products. They clean your skin really well without leaving residue. They moisturize without leaving your skin oily, and after less than a week of use, I'm already seeing improvement in my skin texture. It really is a good value for the price and how much you use each time. All of this with no irritation.

Great for sensitive skin!
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.
