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 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.

tbh I didn't expect much but boy was I wrong. all my stubborn closed comedones gone within a week and bonus my skin texture is improving. ofc my facial wash helps but I wish I thought about salicylic acid much earlier 🥹 this is my first salicylic acid serum and I love it, new HG. I checked ingredients via SkinSort before buying, to make sure it's fungal acne safe and match my other skin concerns. Show more
