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 Review: incredible Vitamin C serum with none of the aggravation - 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! ## Features - [Vitamin C & glutathione for a brighter complexion] Helps improve the appearance of uneven skin tone while enhancing natural radiance. - [Targets dark spots & acne scars] Helps reduce the appearance of pigmentation and marks for smoother, clearer-looking skin. - [Glow-boosting serum for dull skin] Revives tired-looking skin and promotes a brighter, more refreshed appearance. - [Lightweight, fast-absorbing formula] Absorbs quickly without stickiness, making it ideal for daily use and layering. - [Suitable for sensitive skin – daily use] Gentle formula designed for everyday use and suitable for a wide range of skin types. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C61FD7P9 | | ASIN | B0C61FD7P9 | | Active Ingredients | niacinamide,panthenol | | Benefits | Antioxidant, Brightening | | Best Sellers Rank | 4,241 in Beauty ( See Top 100 in Beauty ) 129 in Face Serums | | Brand Name | numbuzin | | Country Of Origin | Korea, Republic of | | Country of origin | Korea, Republic of | | Customer Reviews | 4.3 4.3 out of 5 stars (4,830) | | Customer reviews | 4.3 4.3 out of 5 stars (4,830) | | Item Form | Drop | | Item Volume | 30 Millilitres | | Item Weight | 40 Grams | | Item model number | NBZ-024 | | Manufacturer | BENOW Inc. | | Manufacturer | BENOW Inc. | | Manufacturer Part Number | NBZ-024 | | Material Features | Vegan | | Model Number | NBZ-024 | | Number of Items | 1 | | Product Dimensions | 10 x 5 x 2 cm; 40 g | | Recommended Uses For Product | Brightening,Provides Vitamins,Spread | | Scent Name | Aloe | | Skin Tone | All | | Skin Type | All, Combination, Dry, Normal, Oily | | Special Ingredients | Antioxidants, vitamin_b5, vitamin_c | | Target Use Body Part | Face | | UPC | 691266759780 | | Unit Count | 30.0 millilitre | ## Product Details - **Active ingredients:** niacinamide,panthenol - **Brand:** numbuzin - **Item form:** Drop - **Item weight:** 40 Grams - **Material feature:** Vegan - **Product benefits:** Antioxidant, Brightening - **Scent:** Aloe - **Skin type:** All, Combination, Dry, Normal, Oily - **Special ingredients:** Antioxidants, vitamin_b5, vitamin_c - **Use for:** Face ## Images ![numbuzin No.5 Vitamin C Serum with Glutathione – For Dark Spots & Uneven Skin Tone | Brightening Glow Serum for Radiant Skin | Korean Skincare | 30 ml (1.01 fl. oz.) - Image 1](https://m.media-amazon.com/images/I/61VGNgDfj+L.jpg) ## Questions & Answers **Q: Do iI have to shake it before use it?** A: I shook this product well the first time before using it.

LOVE LOVE LOVE ### ⭐⭐⭐⭐⭐ incredible Vitamin C serum with none of the aggravation *by J***I on 15 October 2024* 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.

Amazing product and one that i will buy forever i expect! ### ⭐⭐⭐⭐ Good serum, hasn’t broken me out, slow results *by B***L on 10 December 2025* 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. ## Frequently Bought Together - numbuzin No.5 Serum | Tranexamic Acid 4%, Niacinamide 5%, Glutathione, Vitamin C | Vitamin Concentrated Serum | Hyperpigmentation| Suitable for Sensitive Skin, Korean Skincare | 1.01 fl. oz. - numbuzin No.5 Toner Pads | Vitamin-Niacinamide Concentrated Pad | Double-Sided | Glutathione, Niacinamide, PHA & LHA | Exfoliation, Hyperpigmentation Care | 70 Pads/180 ml - TOSOWOONG Arbutin 7% + Tranexamic Acid 4% Cream, 70,000ppm Arbutin, 40,000ppm TXA, Niacinamide, Glutathione, Dark Spots, Freckle, Blemishes, Pigmentation, Korean Skin Care, 50ml, 1.69 fl.oz. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/615925548-numbuzin-no-5-vitamin-c-serum-with-glutathione-for-dark](https://www.desertcart.vu/products/615925548-numbuzin-no-5-vitamin-c-serum-with-glutathione-for-dark) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
