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

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!

Good serum, hasn’t broken me out, slow results
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.

Just Okay! Is it actually doing anything?
One of those products I wonder if it’s actually doing anything?! No tingling or sensitivity. It’s a nice texture that sinks in. No instructions how much to use though! Seems to layer with everything else I’ve combined it with it in my routine. Just not convinced it’s doing anything other than hydration and skin softness. Recently, since using this product and sunscreen I have got a dark mark on my upper cheek bone and it doesn’t seem to help brighten it. I find it absurd I have to use several bottles to see anything. So I won’t be buying again once this bottles finished. Which won’t be long! I’m still debating whether this is genuine as Numbuzins own guide doesn’t match this bottle. No date on the bottle & the colour of the product is different to their description. Be aware, there is no Azelaic Acid in the formula. I think previously there was an error in the description which included it, this has since been removed. Just not sure this version of ‘Vitamin C’ is affective especially using one bottle. I think it’s slow progress and you would need to use several if you can commit.

It works
I get spots that turn in to dark spots that don’t go but after using the product Daily under my moisturiser I find them nearly fully faded in a week the price is definitely worth it if you have the same problem

Je crois que c'est au moins mon 3 ème flacon. J'en suis très satisfaite. J'ai remarqué que mes pores son plus petits donc beaucoup moins visible qu'avant et j'ai remarqué une peau plus éclatante qu'auparavant. Sachant que j'ai une peau avec des pors dilatés qui m'ont beaucoup complexés. J'ai aussi remarqué que ça m'a raffermi la peau (effet liftant).

Great HG item. It covers my need for a light concentration of vitamin C, along with TXA and glutathione. After researching the ingredients, it was nice to find this combination without a lot of the skin-aggravating ingredients found in many common or viral products. It definitely helps add to my skin glow. I can't say it helps much with hydration, but I use a Centella ampoule afterward, and that seems to work very well with this. I also haven't noticed any scent, and I'm glad there are no added fragrances. Simple and effective, and I’m very happy with the results. I can't remember the last time I had hyperpigmentation stick around for long with this in my routine.

He estado usando el Numbuzin Nº5 Serum y me ha gustado mucho. Tiene una textura ligera, se absorbe rápido y no deja sensación pegajosa. Con el uso constante he notado la piel más luminosa y uniforme. No me causó irritación y funciona bien dentro de mi rutina diaria. Buen producto.
