Best serum
I have tried many serums for my 40+ sensitive skin with rosacea. This is one of my favorites. Simple formula with only 5% niacinamide so it is not irritating. I hope Glossier continues to make this one.

My Holy Grail
I love this serum. I’ve been using it consistently since ‘23. It’s the only one I’ve found that glides on smoothly, controls oil and doesn’t break me out. One bottle lasts 3 months with daily use. I’ll be a repeat customer for life!
