numbuzinNo.5 Serum | Vitamin Concentrated Serum | Glutathione, Vitamin C | Hyperpigmentation, Acne Scars | Suitable for Sensitive Skin, Korean Skincare | 30 ml

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!

Excellent staple in my teen son skin, helping with acne scars

I've been using the numbuzin No.5 Serum for a few weeks now, and I’m really happy with the results. The texture is lightweight, non-sticky, and absorbs quickly into my skin. It feels gentle and didn’t cause any irritation, which is great because I have sensitive skin.I mainly bought it for dark spots and acne scars, and I’ve noticed my skin tone looking more even and bright. Some of my recent marks have already started to fade. It also gives my skin a healthy glow.Overall, it’s a great serum if you’re looking for something gentle yet effective for brightening and fading spots. I’d definitely recommend it!

In my opinion this is the best Vitamin C serum for sensitive skin! It’s so soothing and doesn’t irritate your skin at all.

I love it very much, it's completely beautiful, I would really recommend it, my face looks great.

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.

Probably my fourth purchase.

Lightens dark spots!
