Azelaic acid vs rice toner

Azelaic has more documented studies to show reduced in PIE.

I've been using Azelaic Acid by Ordinary for 4 months, everyday, together with Niacinamide serum. In my case it helps quicker compared using Niacinamide alone. Never use any Rice Toner, but I'm using Rice sleep mask by COSRx for 3 months, 4 times/week, it doesn't do anything for me.

Better go for Azelaic Acid! Rice toner great to reduce the redness or inflammation but not PIE
