Based on ingredient information published consistently on the brand's own official website and an affiliated e-commerce site, this sheet mask's essence formula is: Water, Erythritol, 2,3-Butanediol, Glycerin, PEG/PPG-17/6 Copolymer, Methyl Gluceth-20, Butylene Glycol, Panthenol, Hydroxyacetophenone, Maltooligosyl Glucoside, Hydrogenated Starch Hydrolysate, Allantoin, 3-O-Ethyl Ascorbic Acid, Citrus Reticulata (Tangerine) Fruit Extract, Carbomer, Hydrolyzed Sclerotium Gum, Arginine, Xanthan Gum, Disodium EDTA, Sodium Hyaluronate, Camellia Japonica Flower Extract, Portulaca Oleracea Extract, 1,2-Hexanediol, Gentiana Scabra Root Extract, Collagen, Hyaluronic Acid, Stephania Tetrandra Extract, Ethylhexylglycerin, Arginine/Lysine Polypeptide, Fullerenes, Oligopeptide-1, Oligopeptide-5, and Oligopeptide-2.

Key Features
Quinsia is a skincare brand marketed and distributed in Bangladesh by Q Cosmetics Ltd, self-described by the brand as "Brightening Korean K-Beauty." We want to note that we were not able to independently corroborate a Korean manufacturing origin through factory or OEM documentation, so this should be understood as the brand's own self-description rather than an independently verified fact. This sheet mask is part of a broader Quinsia "Vitamin C Series" that also includes a face wash, moisturizer, serum, and toner with the same Vitamin C positioning.
Benefits
3-O-Ethyl Ascorbic Acid is a Vitamin C derivative generally considered more stable than pure Ascorbic Acid, associated with antioxidant and brightening support. The formula also includes Sodium Hyaluronate and Panthenol for hydration, and Allantoin for soothing. The ingredient list includes Collagen and several peptides (Oligopeptide-1, Oligopeptide-5, Oligopeptide-2, and an Arginine/Lysine Polypeptide); as with most topical collagen and peptide ingredients in sheet masks, these are generally understood to provide surface-level hydration and conditioning benefits rather than penetrating to stimulate the skin's own deeper collagen production, so we recommend treating strong anti-aging claims with some caution.
Who Can Use This Product
This sheet mask is generally marketed toward those seeking a brightening, antioxidant-focused treatment. Because the concentration of the Vitamin C derivative is not disclosed, and the formula contains numerous botanical extracts and functional ingredients, individuals with known cosmetic sensitivities should patch test before applying to the full face. This product does not appear to contain common irritant acids like Salicylic Acid, so it may be a comparatively gentle choice, though individual sensitivity always varies.
How to Use
Sheet masks of this type are typically applied to clean, dry skin, left on for the time specified on the packaging (commonly 15-20 minutes for this product category), then removed, with any remaining essence gently patted into the skin rather than rinsed off. Please follow the instructions printed on the packaging, which take precedence over this general guidance.
Storage & Safety
Store in a cool, dry place away from direct sunlight. Keep out of reach of children. Avoid contact with the eyes; if contact occurs, rinse thoroughly with water. Discontinue use if irritation, redness, or an allergic reaction develops, and consult a doctor if symptoms persist. Individuals with known sensitivities to any of the botanical extracts, peptides, or Vitamin C derivatives listed above should review the full ingredient list before use.

A: 3-O-Ethyl Ascorbic Acid, a relatively stable Vitamin C derivative. The specific concentration was not disclosed by any source we checked.

A: The brand describes itself as "Brightening Korean K-Beauty," but we were not able to independently corroborate a Korean manufacturing origin through factory documentation, so we present this as the brand's own self-description.
