Repeat customer very happy with the product

Such a great product. My skin is spot less and even toned. Started working after 1 week of use. Would definitely recommend for hyper pigmentation and uneven skin tone.

Today is just my 4th night applying this serum on my face and I think its good.No rashes,no redness and I think it’s suitable to my skin the product is original

Second time buying this serum! Really helps even my skin out!!!

I have just used it for a week and find it quite sticky specially after applying the sunscreen or thé moisturizer, too soon to comment if it’s working , will continue till the product finishes

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

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.

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!

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
