Buffering, Masking
Loved

Azelaic acid is a naturally occurring acid derived from grains. This ingredient is effective in treating acne, rosacea, and other skin conditions.

It has been shown to reduce the growth of acne-causing bacteria and helps reduce inflammation. On top of that, it helps reduce the production of sebum and unclog pores.

Azelaic Acid also has antioxidant properties. Antioxidants protect our skin cells from free-radical damage.

One of the main benefits of azelaic acid is that it is gentle and well-tolerated by most people. It is also non-comedogenic, meaning that it will not clog pores.

Fun fact: The lab-created form of azelaic acid is typically used within cosmetic products for its shelf-stability.

I’m on my third bottle
Want a simple, hydrating, scentless, and affordable azelaic acid serum? Look no further! Azelaic acid is well tolerated by many and for me I’ve noticed great improvements regarding redness. 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 extract, panthenol, and niacinamide so it feels very soothing. Keep in mind however that there are a few different plant extracts in this as well, so if you are super extra sensitive you might react poorly to them. But personally I’ve never found them to be an issue.

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.
