An effective azeleic acid serum. One of my gripes about Azeleic products is normally the texture and how it settles powdery or pilling. This however is elegant emulsion feel, spreads well and doesn’t pill! Really helped with my texture and overall. There is a slight smell (not fragrance) but it doesn’t bother me, disappears after a few seconds.

There was a short period of time when I cut this out of my routine, and that’s when I noticed how much it had been doing to reduce redness in my skin. This serum also contains aloe Show more
I was so excited to try a product with what seemed like no comedogenic ingredients, but I suspect all the extracts broke me out pretty badly. I’m talking deep, painful cysts. I think I saw a nice effect on skin brightness, but that’s the only upside unfortunately. This also left a chalky white residue at times.
