numbuzin No.5 Serum | Glutathione Vitamin Concentrated Serum | Glutathione, Vitamin C, Tranexamic Acid | Hyperpigmentation, Acne Scars | Suitable for Sensitive Skin, Korean Skincare | 1.01 fl. oz.

I love most of the products from Numbuzin, they are affordable yet effective. I have been using multiple products from them and loving it.

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.

Hmm haven’t seen result on skin brightening and I feel like the formula isn’t for my very oily combination skin maybe to thick maybe it’s because I find all Korean products abit thick but I’m starting to use it for my neck to see if there will be any bright effects started this week

Repeat customer very happy with the product

10/10 very useful

Fair

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!!!

Value for money and mosturizing.

Si me ha gustado, comencé a ver resultados en mis manchas, sin embargo, la misma marca tiene un producto más potente y ese es el que he estado usando como mantenimiento si lo compraría

It doesn't have any effect. It's just a waste of money. Also, the customer service is terrible. Although they promised a return, as advertised, the seller refused to process the return. Overall rating is 0, if that were an option. I do not recommend it. You can buy much better products from well-known brands for the same price.

Numbuzin no. 5 is one of the best vit c serums I've used. No irritation, no side effects. Only thing it's on the expensive side but it's worth it. Gives a glow to the skin.

incontournable pour une peau plus nette et radieuse. Sa texture légère pénètre rapidement laissant la peau douce, et effacé les tâches pigmentaire je recommande vivement
