numbuzin No.5 Vitamin Concentrated Serum, Dark Spot Care, Glutathione & Vitamin Serum, Korean Skincare, Tranexamic Acid 4%, Niacinamide 5%, for a Radiant-Looking Glow 1.01 fl oz

Value for money and mosturizing.

Improvement is visible within few weeks. I was sceptical about buying it. However I guess I made right decision.

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.

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

100% good little drops works wonders

I was expecting brightness with this as it is a concentrated vitamin serum but I didn't get the result I wanted. I'd rather go for vitamin c serums than this. Has this rough texture that i didnt like as well

This really helps my skin to look brighter and even. Mild on the skin as well

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!

Most soothing Vitamin serum! I haven’t used this one long yet, so result wise I can’t tell much. But this serums feels super soothing and makes my skin plump. Doesn’t clog pores and feels hydrating. I have sensitive skin and it didn’t break me out so far

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

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.

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.
