Numbuzin - No.5 Vitamin Concentrated Serum

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!

I'm still adapting, the first time I used it I got pimples, the second time my skin peeled, I still don't know what I'm doing wrong or if it's just not for me... but as soon as it's applied to the skin it gives a glow

Is just 3days now after two weeks I will come back for my review

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.

J’aime beaucoup ce sérum. Très agréable sur la peau. Je ne l’utilise pas tout le temps donc je n’ai pas encore assez d’utilisations pour parler de son efficacité mais il convient très bien pour les peaux mixtes et grasses. Je recommande.

Au bout de 3 mois à l’utiliser tous les matins et en pensant à mettre ma crème solaire après, j’ai vu un éclaircissement significatif de mes tâches profondes que j’ai depuis plusieurs années. Fonctionne aussi très bien sur les tâches post-acné.

Since I easily get acne scars, I have tried a lot of different viral products, but this one is definitely the best so far. Effective and suits my sensitive skin too.

Love this vitamin C. First bought it in Korea. Glad to to see it available here. Drys well on skin

Très bon serum qui illumine le teint

Bonjour. Merci pour votre produit.

Best for brightening nd dark spots must try✨

Works perfect for daily use! But not as quick to work.

Good product for the face and light too not sticky .

Excellent staple in my teen son skin, helping with acne scars

This is the best vitamin C serum out there. I also love that it has tranexamic acid and alpha albutrin, and glutathione! It’s pretty gentle on my skin and is great at fading hyperpigmentation. I use it every morning and will definitely be repurchasing.

I've been using the numbuzin No.5 Serum for a few weeks now, and I’m really happy with the results. The texture is lightweight, non-sticky, and absorbs quickly into my skin. It feels gentle and didn’t cause any irritation, which is great because I have sensitive skin.I mainly bought it for dark spots and acne scars, and I’ve noticed my skin tone looking more even and bright. Some of my recent marks have already started to fade. It also gives my skin a healthy glow.Overall, it’s a great serum if you’re looking for something gentle yet effective for brightening and fading spots. I’d definitely recommend it!

Sérum très efficace. On voit bien les résultats au bout de deux semaines

3-MONTH RESULTS (2x day):Slight fading of deep dark acne scars and age spots. Evens out skin tone. Gentle and not irritating. I am guessing this will take 6 to 9 months for deeper scars to fade. The pamphlet on Yesstyle.com shows 9.65% improvement in Blemishes after 4 weeks and 18.9% for even skin tone (this means expect slow steady results). They recommend also using the toner pad for faster results (165% improvement) but the combo irritated my skin. Overall, I like that it is gentle and will continue using it, right after the Toner.KEY INGREDIENTS:Contains the right chemicals known to fade dark spots like Glutathione, 4% Tranexamic Acid, 5% Niacinamide (both suppresses melanin), Alpha-Arbutin, Vit C, 3-0-Ethyl Ascorbic Acid, Tumeric etc.TEXTURE:Light serum, not sticky, absorbs quickly after Toner. Tap face gently for a few seconds after applying to help the skin absorb quicker before adding the next product (tip from korean skincare companies that works).ACNE PREVENTION TIPS: Best way to see improvement of skin is to keep the pores clear and acne from re-surfacing. I have not had a single breakout in 3 months using this routine. Also changed my skin type from Oily Combo to Normal.STEP 1 (2x day) - Use SEBUM CONTROL TONER to regulate skin oil production (I use NUMBUZIN No. 1 blue bottle)STEP 2 (2x day) - Use ANTIBACTERIAL SERUM to reduce inflammation (I use Beauty of Joseon Glow Serum w/60% propolis, Tea Tree)STEP 3 (2x week) - EXFOLIATE to keep pores clear, as clogged pores breed acne. I use Beauty of Joseon Ground Rice and Honey mud mask. Leave on face and neck for 15 minutes; this is a very gentle product. STEP 4 (Optional) - EAT food that aide the digestive system and help prevent acne like Yogurt, Kimchi and Sauerkraut (eat small amounts 2-3 times a week).I hope these tips are helpful to everyone.

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.

I love it! I have purchased it so many times right now. I have used 3 or 4 bottles already. It's not irritated my skin at all and has a light texture that you can use as your skin base everyday without any problems.Need to mention that it takes time(as it should) to brightens the acne scars especially the deep scar. But it does improved the skin tone all-over

Bon sérum antioxydant, et éclaircissement j'aime beaucoup je le recommanderai, il s'aborde rapidement

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

good

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.

Je valide, bon produit pour ma peau, texture agréable, pique un peu mais efficace pour un soin ciblé contre les traces d’imperfections tenaces.
