Product overview
Key Ingredients
- Important discrepancy flag -- Alpha Arbutin: despite being named in this product's title and in the brand's own marketing copy, Alpha Arbutin does NOT appear anywhere in the full ingredient list confirmed via two independent sources (the official brand site and a Bangladesh retailer, both showing an identical panel). This is a genuine, verifiable mismatch between the product name/marketing and the disclosed formula. MedEasy does not state that this product contains Alpha Arbutin, since the confirmed ingredient panel does not support that claim -- customers specifically seeking Alpha Arbutin should verify against their physical product box before purchasing
- 3-O-Ethyl Ascorbic Acid (Vitamin C form): confirmed as the Vitamin C derivative used, appearing 10th of 25 ingredients -- consistent with a moderate, supporting-level inclusion rather than a headline concentration. No percentage is disclosed
- Niacinamide: present, listed 4th (right after Water, 2,3-Butanediol, and Glycerin), which is consistent with -- but does not independently prove -- the labeled "3%" concentration; this remains a brand marketing claim without independent lab verification
- Tranexamic Acid, Hydrolyzed Collagen, Sodium Hyaluronate, Allantoin: additional actives and hydration-support ingredients confirmed in the full panel
- Full confirmed INCI list: Water, 2,3-Butanediol, Glycerin, Niacinamide, Tranexamic Acid, Butylene Glycol, Hydrolyzed Collagen, Methyl Gluceth-20, Glycosaminoglycans, Hydroxyacetophenone, 3-O-Ethyl Ascorbic Acid, Jojoba Wax PEG-120 Esters, Allantoin, Sodium Hyaluronate, Xanthan Gum, Disodium EDTA, Gentiana Scabra Root Extract, Portulaca Oleracea Extract, 1,2-Hexanediol, Stephania Tetrandra Extract, PEG-40 Hydrogenated Castor Oil, Caramel, Camellia Japonica Flower Extract, Fullerenes, Ethylhexylglycerin, Arginine/Lysine Polypeptide
Key Features
- Quinsia describes itself on its own official site as "a Korean global brand." MedEasy could not find a manufacturing address, factory location, or corporate registration independently confirming Korean origin, so this should be understood as a brand self-description rather than an independently verified fact
- Sold in Bangladesh via Q Cosmetics Ltd / Q Beaute retail channels
- Combines Vitamin C (as 3-O-Ethyl Ascorbic Acid), Niacinamide, and Tranexamic Acid in a single antioxidant-focused serum
Benefits
- Niacinamide at a marketed 3% supports a more even skin tone and skin barrier function
- 3-O-Ethyl Ascorbic Acid contributes antioxidant support, though at a moderate rather than headline concentration based on its position in the ingredient list
- Tranexamic Acid and Hydrolyzed Collagen are included for additional brightening-supportive and skin-conditioning benefits
- Sodium Hyaluronate and Allantoin support hydration alongside the active ingredients
Who Can Use This Product
- Adults looking for a Vitamin C, Niacinamide, and Tranexamic Acid antioxidant serum, with the understanding that Alpha Arbutin -- despite appearing in the product name -- is not supported by the confirmed ingredient panel
- Those specifically seeking Alpha Arbutin for brightening should verify the ingredient panel on their physical product or choose a different serum
- Those with known sensitivities to any listed ingredient should patch-test before regular use

- Apply a few drops to clean, dry skin after cleansing, before heavier creams or oils

FAQ (Frequently Asked Questions)
Q: Does this serum actually contain Alpha Arbutin, as the product name suggests?
A: MedEasy found that Alpha Arbutin does not appear in the full confirmed ingredient list, despite being named in the product title and brand marketing. This is a genuine discrepancy -- customers specifically seeking Alpha Arbutin should verify against their physical product box before purchasing.
Q: Is the "3% Niacinamide" claim verified?
A: Niacinamide is listed 4th in the ingredient panel, which is consistent with a meaningful concentration, but the specific "3%" figure is a brand marketing claim without independent lab verification.
Q: Is Quinsia really a Korean brand?
A: The brand describes itself as Korean on its own official site, but MedEasy could not find independent confirmation (manufacturing address, factory, or corporate registration) of Korean origin, so this should be understood as a brand self-description.
Q: What form of Vitamin C does this serum use?
A: 3-O-Ethyl Ascorbic Acid, a stable Vitamin C derivative, appearing 10th of 25 ingredients -- a moderate, supporting-level inclusion rather than a headline concentration.
