No.5 Serum | Vitamin Concentrated Serum | Glutathione, Vitamin C | Hyperpigmentation, Acne Scars | Suitable for Sensitive Skin, Korean Skincare | 30 ml

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

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!

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.

This is the best vitmin C serum in the world!. I will purchase forever.

Good for the skin

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.

Amazing product but may need to build up use a quite strong

Glow skin and the skin softy

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).

Ottimo siero è leggero e non appiccica. È la seconda volta che lo ricompro. Consegna abbastanza veloce e ad un buon prezzo.

The ingredient list is impressive, all work together to target pigmentation and give my skin a more even tone. It help keep my skin calm and hydrated. The texture is lightweight and absorbs quickly, no sticky residue. I use it both morning and night, and it layers really well under moisturizer and SPF. I noticed my complexion looking more radiant. Dark spots from previous breakouts are fading, and overall, my skin tone feels more balanced.

I love it actually.i have been using this serum since last year i also recommend to my friends and my mother and she love it .she repurchased this like 7 times .its great for hyperpigmentation and skin discolouration and also dull skin .give it a try
