## Description

No.9 Line for Fine Lines BEST SELLERS No.1 Line for Acne-Prone

Review: incredible Vitamin C serum with none of the aggravation - i have used a number of vitamin c serums and i just havent been able to get on with any so far. L-ascorbic acid can be very aggravating to many people, causing sensitive skin that can flake and peel before getting used to the active ingredients. the way numbuzin has formulated this No.5 serum is incredible. It still has a slight hot dog water smell (if you know you know!) but its very mild, but it feels amazing on the skin. its left looking glowy but not artificially so, and i have seen a definite improvement to my skins texture and radiance. Best of all, there has been absolutely zero irritation. Amazing product and one that i will buy forever i expect!
Review: Love it - reduces darkness and pigmentation - I love this so much. I instantly noticed a difference after my first use and in 4 uses my skin feels transformed. I was really struggling with darkness/pigmentation for a while and couldn't figure out why but this restored and brightened my skin I'm so happy. I would probably repurchase forever. LOVE LOVE LOVE

### ⭐⭐⭐⭐ Good serum, hasn’t broken me out, slow results
*by B***L on 10 December 2025*

So far so good, nice consistency, not too runny or sticky. Cloudy serum which has helped to brighten skin over the last 2 weeks. Works well with microneedling, didn’t cause too much irritation. Also hasn’t broken me out or caused any reactions even though I have acne-prone skin. 4 stars because results are very slow…. Hasn’t brightened as much as I would’ve hoped over the last 2 weeks, will see if using for a month makes a difference.
