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

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.

It is so effective, highly recommended.

Happy

2nd time repurchasing. My favorite vit c serum. I look forward to applying every morning. Pairs well with the numbuzin sunscreen.

Love love

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.

powerful yet non irritating ! deffinitely can see the results. A serum that actualy works.

Its fake. The serum looks different.
