[GLUTATHIONE] Glutathione is a well-known supplement especially in Korea, taken either orally or through injections to brighten dull, uneven skin tone and to fade hyperpigmentation, dark spots, and acne marks.

[CLINICALLY TESTED] Clinically proven to even out skin tone by 18.90% and reduce dark spots by 9.65% in 4 weeks. Hypoallergenic and skin irritation tests completed, making it safe to use for sensitive and acne-prone skin types.
[RECOMMENDED FOR] All skin types: oily, dry, combination, acne-prone, and sensitive skin. Especially recommended for the following skin concerns: hyperpigmentation, dark spots, acne scars and marks, dull and tired complexion

This brand is my new secret weapon
I went in with no expectations. I saw it on sale and I have other items from this brand that I love but very different types and I thought I had nothing to lose. This serum is amazing. Three drops and it spreads so smoothly and easily. It has vitamins, antioxidents, no scent and I now can not live without it. My skin is the best it has been in a long time. My little bumps are almost gone. I think it would work for all skin types too. I will definitely repurchase because even regular price it is affordable.

Worth the money
This is a great daily serum to add to your skincare routine. It provides softness and moisture to the skin while also fading dark spots/acne marks. I love to use this twice a day, in the morning and at night. You can also use this before putting on makeup.

I go to a Korean place for my facials. She recommended it once and I live by it. I use it EVERY morning! Love that I can buy off amazon and it is quick and typical Korean packaging. Great quality for a great price. Keeps my skin hydrated with boosts of antioxidants , hyperpigmentation help and anti aging properties!! A must try

Subtle Yet Effective
Iâm almost done with the bottle, so I wanted to leave a review. Iâve tried several products from Numbuzin, and while their popular toner didnât work for me (unfortunately), I decided to give this serum a try despite my initial doubtsâand Iâm pretty satisfied with it!This serum contains glutathione and vitamin ingredients, which are known for their brightening and skin-tone-evening effects. While itâs not a dramatic change, after using it consistently, Iâve noticed that my complexion looks a bit brighter and more even. Itâs not a miracle worker, but it definitely helps to improve skin tone over time.The texture is nice and smooth, but it does feel slightly sticky when first applied. Because of this, I usually wait a little while for it to fully absorb. Once itâs absorbed, the stickiness goes away, and my skin feels soft and moisturized. Itâs not a dealbreaker for me, but itâs something to keep in mind if you’re in a hurry.Pros:Noticeable brightening and evening of skin tone with consistent useContains glutathione and vitamin ingredients that are great for skinGood texture, leaves skin soft and moisturizedThe slight stickiness dissipates after absorptionCons:Slight stickiness that requires a bit of waiting for full absorptionNo dramatic changes, but subtle improvements with continued useOverall, Iâm pleasantly surprised by the Numbuzin No.5+ Vitamin Concentrated Serum. Itâs gentle on the skin, and with consistent use, Iâve seen a gradual improvement in my complexion. If youâre looking for a product with glutathione and vitamin ingredients, this is definitely worth trying!

Very gentle brightening serum with modest results
I have sensitive, dry skin that is prone to hyperpigmentation from the sun. I’ve been using this serum for about two months now so I feel confident discussing what it can (and can’t) do for my skin. The serum is very hydrating and gentle, and I was surprised to find it NEVER irritated my skin – even when my skin barrier was compromised and I was dealing with irritation from another product. That alone is enough for me to be impressed! It’s also got a very rich, gorgeous texture. I’d say it’s on the thicker side, and has a lot of glide to it as you apply it across your face. I find it to be hydrating and moisturizing, but because it’s so rich it does take a second for it to sink in. I usually wait about 30 seconds before it dries down completely. Something I also appreciate is how dewy it makes my skin.Over the past two months I’ve noticed some modest but definite brightening from the serum. My dark spots have faded a bit and my skin is more plump and smooth. I notice less redness and irritation around my nose as well. But you shouldn’t expect this to work miracles – this serum seems to work best as a gentle, progressive brightener rather than an intense active. It’s perfect for someone like me who wants to benefits of a brighter skin tone without the irritation of harsher actives.This is very easy to integrate into almost any skincare routine, but here is a breakdown of who I think this serum is good for based on my own personal experience with it:This is for you if:-If you deal with hyperpigmentation from the sun or post-acne marks-If you want a brighter complexion but don’t want to use harsh actives-If you use other more intense actives (AHAs, Retinol, etc.) and you want a little “boost”-If you have dry and dehydrated skin and need a serum that will help hydrate and moisturizeThis is NOT for you if:-You expect this to make a drastic difference in your dark spots-You have very oil or acne prone skin-You are looking for a vitamin C serum

Amazing for hyper pigmentation, glowy , moisturizing

Hyperpigmentation buster
This product has worked the best to lessen hyperpigmentation than any other product I have ever used and I have used a lot. I was shocked to see improvement in the first week but the results keep getting better every week. I donât understand why anyone would rate this less than 5 stars. This company really puts a lot of thought into their products. Their toner number 3 is amazing as well for those who have dry skin like me. Love, love this company!

Mixed.results
The numbuzin No.5+ Vitamin Concentrated Serum is a mixed bag. While the serum absorbs quickly and has a pleasant texture, I haven’t noticed any significant improvement in my dark spots after consistent use. It does leave my skin feeling hydrated and slightly brighter, but the promised brightening effect is underwhelming. Additionally, the bottle is quite small for the price point. Overall, it’s a decent product but doesn’t live up to the hype.
