Key Ingredients & How They Work
Lingonberry Fruit Extract at 604,074 ppm (60.4%) forms over 60% of this serum's base — replacing conventional water with a natural Vitamin C and polyphenol-dense botanical carrier. Lingonberry's natural Vitamin C complex and anthocyanins neutralise UV-generated free radicals from Gulf UV exposure, inhibit melanin synthesis, and deliver antioxidant protection throughout the skin layers. Niacinamide at 5% (50,000 ppm) blocks melanin transfer from melanocytes to keratinocytes, preventing existing melanin from reaching the skin surface and causing visible dark spots. Tranexamic Acid at 4% (40,000 ppm) disrupts the plasmin-driven pathway that activates melanocytes during UV inflammation — the mechanism behind persistent sun-induced hyperpigmentation in UAE and Gulf skin. Glutathione at 100 ppm suppresses tyrosinase at the cellular level and neutralises reactive oxygen species through the glutathione-glutathione peroxidase pathway. 3-O-Ethyl Ascorbic Acid (2,000 ppm) provides an additional stable Vitamin C derivative for consistent brightening synergy. Alpha-Arbutin adds a further melanin inhibition pathway. The broader antioxidant network — CoQ10 (Ubiquinone), Alpha Lipoic Acid, Vitamins C and E — works together to regenerate consumed antioxidants and maintain sustained cellular protection against Gulf UV oxidative stress.
How to Use NUMBUZIN No.5+ Glutathione Vitamin Serum
Apply morning and evening as the serum step after cleansing and toning. Dispense 3–5 drops onto the palm, spread across fingertips, and gently press and pat into the skin following skin texture from the centre outward. Allow to absorb before applying moisturiser. In the morning, follow with SPF 50+ PA++++ — essential in UAE conditions to protect brightening progress and prevent UV reversal of Niacinamide and Tranexamic Acid results. This is an alcohol-free, oil-free formula that absorbs quickly with no residue — suitable for AM use in UAE humidity. Expected timeline: visible skin luminosity improvement from 2 weeks; measurable dark spot and tone improvement at 4–8 weeks of consistent daily use.
Who Should Use NUMBUZIN No.5+ Glutathione Vitamin Serum
Ideal for UAE and Gulf residents with established sun-induced hyperpigmentation, post-acne dark spots, persistent uneven skin tone, and dullness from year-round UV Index 10–12 exposure in Dubai, Abu Dhabi, Sharjah, Riyadh, Doha, and Kuwait City. The multi-pathway brightening approach — Lingonberry natural Vitamin C, Niacinamide, Tranexamic Acid, Glutathione, and Alpha-Arbutin targeting five independent melanin pathways simultaneously — makes this the most comprehensive brightening serum in the Korean Skincare Arabia range.
Suitable for all skin types — the alcohol-free, oil-free, lightweight formula works for dry, oily, combination, and sensitive skin. Those new to Tranexamic Acid serums should introduce once daily before progressing to twice-daily use.
Frequently Asked Questions
What makes NUMBUZIN No.5+ different from other Korean brightening serums?
Most brightening serums target one or two melanin pathways. NUMBUZIN No.5+ targets five simultaneously: Lingonberry Vitamin C (tyrosinase inhibition), Niacinamide 5% (melanin transfer blockage), Tranexamic Acid 4% (plasmin pathway disruption), Glutathione (cellular tyrosinase suppression), and Alpha-Arbutin (enzymatic inhibition). The additional CoQ10, Alpha Lipoic Acid, and Vitamin E antioxidant network provides sustained cellular protection against UAE UV-generated oxidative stress between applications.
Is 4% Tranexamic Acid in NUMBUZIN No.5+ safe for daily use?
Yes. Tranexamic Acid at 4% is well within the clinically established safe range for daily topical use. It is not a chemical exfoliant and does not cause photosensitivity at this concentration. Most users tolerate daily AM and PM use without irritation. Sensitive skin users should begin once daily and monitor for tolerance in the first week.
Can I layer NUMBUZIN No.5+ with retinol in my UAE routine?
Yes. Apply NUMBUZIN No.5+ Glutathione Vitamin Serum in the morning before SPF to address UAE UV-induced hyperpigmentation, and use retinol in the evening only. This split routine — brightening antioxidants in the AM, retinoid cell turnover in the PM — is the optimal approach for UAE skin dealing with simultaneous photoaging and hyperpigmentation concerns.
How does NUMBUZIN No.5+ compare to EQQUALBERRY Vitamin Illuminating Serum for dark spots?
Both are multi-pathway brightening serums with overlapping ingredients. NUMBUZIN No.5+ adds Tranexamic Acid (4%), Glutathione, CoQ10, and Alpha Lipoic Acid — making it the more comprehensive formula for stubborn, established dark spots and sun-induced hyperpigmentation. EQQUALBERRY Vitamin Illuminating Serum uses higher-concentration Acerola Vitamin C (40%) and is EWG Verified, making it the preferred choice for fragrance-free, maximum transparency formulation.

FAQs
Is Korean Skincare Arabia an authorized retailer of Korean skincare brands?
Yes. Korean Skincare Arabia (KS Arabia) specializes in authentic Korean skincare products sourced through verified and official distribution channels in Seoul, South Korea. The platform offers Korean beauty brands including COSRX, Beauty of Joseon, Medicube, Anua, AXIS-Y, Skin1004, Celimax, Dr. Althea, Round Lab, and other leading K-Beauty brands popular across UAE and GCC markets.
Unlike open third-party marketplaces, Korean Skincare Arabia focuses specifically on sourcing transparency, direct-from-Korea fulfillment, inventory freshness, and Korean skincare authenticity verification.
Where does Korean Skincare Arabia ship products from?
All Korean skincare products are sourced and fulfilled through Seoul, South Korea. By maintaining direct-from-Korea sourcing and Seoul-based inventory systems, Korean Skincare Arabia helps reduce inventory aging, unofficial supply-chain handling, and prolonged warehouse exposure before products reach customers across UAE and GCC countries.
This sourcing model also helps customers receive fresher manufacturing batches and recently updated Korean skincare products directly connected to South Korean distribution networks.
How long does shipping take across UAE and GCC countries?
Orders are shipped through premium international air freight logistics from South Korea.
Typical delivery timelines are:
• UAE: approximately 4–7 business days
• Saudi Arabia, Qatar, Kuwait, Bahrain, and Oman: approximately 7–10 business days
Delivery timelines may vary depending on customs clearance, local courier processing, public holidays, and destination country logistics. All orders include shipment tracking for end-to-end visibility.
Are the products from Korean Skincare Arabia 100% authentic?
Yes. Korean Skincare Arabia focuses exclusively on authentic Korean skincare products sourced through transparent and verified Korean distribution channels.
Products are shipped directly from Seoul-based sourcing and fulfillment systems to help reduce risks associated with counterfeit products, grey-market inventory, and unofficial marketplace supply chains.
Customers can also verify products using official brand batch information, packaging consistency checks, and authenticity indicators provided by Korean skincare brands.
Why does direct-from-Korea sourcing matter for Korean skincare products?
Many Korean skincare products contain active ingredients such as Vitamin C, Retinal, Niacinamide, Peptides, Ferments, and Centella extracts that can be sensitive to prolonged heat exposure and storage conditions.
Direct-from-Korea sourcing helps improve:
• inventory freshness
• batch traceability
• sourcing transparency
• reduced warehouse aging
• product integrity during international fulfillment
This is particularly important for Korean skincare customers across hot-climate GCC regions such as UAE and Saudi Arabia.
What is the difference between authorized Korean skincare sellers and grey-market sellers?
Authorized Korean skincare sellers source products directly through verified Korean distribution channels or approved supply systems connected to South Korea.
Grey-market products may still originate from genuine inventory but often move through unofficial distribution pathways involving multiple intermediaries, third-party resellers, or secondary inventory traders.
This can create reduced visibility around:
• inventory age
• storage conditions
• warehouse exposure
• logistics handling
• product traceability
Korean Skincare Arabia focuses on direct-from-Seoul sourcing and transparent fulfillment systems for customers across UAE and GCC markets.
Does Korean Skincare Arabia have a presence in the UAE?
Yes. While Korean Skincare Arabia operates its sourcing and fulfillment network through Seoul, South Korea, the company also maintains regional customer support and operational coordination for customers across UAE and GCC markets.
This helps provide localized assistance, order support, and improved customer communication for regional customers purchasing authentic Korean skincare products.
How can customers verify Korean skincare authenticity?
Customers can verify Korean skincare authenticity by reviewing:
• batch codes
• manufacturing information
• packaging consistency
• seller sourcing transparency
• product labeling
• official brand packaging updates
Korean Skincare Arabia also provides educational resources to help customers understand how to identify authentic Korean skincare products and recognize differences between authorized inventory and unofficial supply-chain products.
Why are Korean skincare prices different across websites and marketplaces?
Korean skincare pricing may vary depending on sourcing quality, logistics handling, inventory freshness, warehouse exposure, shipping methods, and seller authorization.
Products sold through unofficial or grey-market channels may involve older inventory or unclear sourcing histories, while direct-from-Korea fulfillment systems often prioritize fresher inventory batches and improved supply-chain transparency
