’ve been using the numbuzin No.5 Vitamin Concentrated Serum every single day, and it has truly become a staple in my skincare routine.As someone with acne-prone skin, I’m always cautious with vitamin serums because many can feel heavy or trigger breakouts. This one has worked beautifully for me. The formula is lightweight, absorbs quickly, and doesn’t leave any sticky or greasy feeling. It layers well under moisturizer and sunscreen without pilling.Over time, I’ve noticed gradual improvement in dullness and post-acne marks. My skin looks brighter and more even, but still feels calm and balanced — not irritated or overwhelmed.Pros:* Lightweight and fast-absorbing* Gentle on acne-prone/sensitive skin* Helps with dullness and post-acne marks* Suitable for daily useCons:*The quantity feels a bit less for the price, especially if you use it dailyOverall, it’s a gentle yet effective vitamin serum that works well for everyday use. I just wish it came in a slightly larger bottle!
Je crois que c'est au moins mon 3 ème flacon. J'en suis très satisfaite. J'ai remarqué que mes pores son plus petits donc beaucoup moins visible qu'avant et j'ai remarqué une peau plus éclatante qu'auparavant.Sachant que j'ai une peau avec des pors dilatés qui m'ont beaucoup complexés.J'ai aussi remarqué que ça m'a raffermi la peau (effet liftant).
The amount of Glutathione in an effective serum must be at least 10,000ppm to 20,000ppm (1% to 2%), but this one has only 100ppm(0.01%) which is equivalent to none. I don't know if it's vitamins concentrate effective or not, but this serum will not provide any out of the box benefits of Glutathione.
Got a day earlier and got the real one..!

I’ve been using this 5% Glutathione + Vitamin C serum for a few weeks now, and I’m seriously impressed. The texture is lightweight and absorbs quickly without leaving any sticky residue — perfect for layering under moisturizer or sunscreen.What I love most is the visible glow and brightness I’ve noticed. My skin tone looks more even, and it’s helped fade some recent acne marks too. The combo of glutathione and vitamin C really packs a punch — my face feels smoother and healthier overall. It also helps with the white heads and large pores on my nose!

What I LIKE about it:1) PACKED WITH VITAMINS — The Numbuzin #5 serum is loaded with vitamins, especially vitamin C, and has really helped brighten up my complexion. After using it for a few weeks, my skin looks noticeably more radiant and even-toned. It’s perfect if you want that natural glow without makeup!2) SO LIGHTWEIGHT AND ABSORBS QUICKLY — The texture is smooth and lightweight, so it doesn’t feel heavy or sticky. It absorbs in seconds, leaving my skin soft and prepped for other products. Great for layering with other serums or creams without any pilling.3) GENTLE ENOUGH FOR DAILY USE — I was worried it might be too strong, but it’s actually quite gentle. My skin hasn’t had any irritation, even with daily use, and it feels more hydrated and healthy over time.DISLIKE: The only downside is the bottle size—I go through it fairly quickly, and a larger option would be amazing!I hope you found this review HELPFUL. Makes reviewing worthwhile. Thank you.
I love most of the products from Numbuzin, they are affordable yet effective. I have been using multiple products from them and loving it.
Great HG item. It covers my need for a light concentration of vitamin C, along with TXA and glutathione. After researching the ingredients, it was nice to find this combination without a lot of the skin-aggravating ingredients found in many common or viral products.It definitely helps add to my skin glow. I can't say it helps much with hydration, but I use a Centella ampoule afterward, and that seems to work very well with this. I also haven't noticed any scent, and I'm glad there are no added fragrances.Simple and effective, and I’m very happy with the results. I can't remember the last time I had hyperpigmentation stick around for long with this in my routine.
Really love how this serum is working wonders on my skin. Skin is starting to glow and look vibrant again.
Yep love it, will reorder
Es bueno.

El mejor suero para manchas
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
Best serum I ever used.
Al aplicarlo de noche , al día siguiente se siente muy bien la piel, si me gustó , y n cuánto a las manchas aún no veo cambios notables pero siento que con el uso constante si puede funcionar.
Got my package today..and found out its LEGIT..the seller and the product is LEGIT..the dropper and the bottle is separate..and in the box you can find a mark glutathione that was little cut and like hanging...👌👌thank you so much.
10/10 very useful
Ottimo siero è leggero e non appiccica. È la seconda volta che lo ricompro. Consegna abbastanza veloce e ad un buon prezzo.
Excellent body wash. Pyunkang Yul Product line is great for sensitive skin. Like their other products, the body wash is calming and very gentle on your skin. Great for dealing with irritated skin. Never over strips. I love their body wash.
this Serum together with azelaic acid from "the ordinary" and on top think layer bio sheabutter makes the skin very firm, plump with even skintone.Using morning and evening and fast results. Amazing
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.
Loving my new regiment of Korean skincare and this No 5 is part of it.Will never not use it
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
It’s a great body wash for ph balance. It’s fragrance free and gentle on my skin.

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.

Tengo que esperar un tiempo para empezar a notar cambio, de momento puedo decir que se absorbe bien y deja un buen aspecto en la piel. Hay que ser constantes
