Product overview
Key Ingredients
- Hyaluronic Acid: the headline hydrating ingredient; retailers list it at "10%," though MedEasy could not independently verify this figure against an official source
- Niacinamide: retailers list it at "5%" for brightening/barrier support; not independently verified
- Vitamin C and Vitamin E: some retailer listings cite implausibly high figures ("30% Vitamin C" and "10-30% Vitamin E") for these ingredients. These percentages are far above typical cosmetic formulation ranges (Vitamin C serums are usually formulated at 20% or below, and Vitamin E at well under 1%) and should be treated as likely marketing exaggeration or a listing error rather than verified fact
- Sourcing caveat: MedEasy could not find a complete, SKU-specific INCI ingredient list for this exact "4 in 1" product. A closely related Sadoer Hyaluronic Acid serum's official ingredient list includes Water, Glycerin, Propylene Glycol, Glycereth-26, Phenoxyethanol, Methylparaben, Carbomer, Triethanolamine, Hydroxyethyl Cellulose, PEG-40 Hydrogenated Castor Oil, Caprylhydroxamic Acid, Disodium EDTA, Fragrance, Hyaluronic Acid, PEG-10, Glyceryl Caprylate -- this is indicative brand-formulation context only, not confirmed identical to this exact SKU
Key Features
- Manufactured under the Sadoer brand; linked in a UK trademark filing to Guangzhou Aise Biotechnology Co., Ltd, China
- "4 in 1" refers to a marketing bundle of hydrating, repairing, brightening, and fine-line-smoothing functions attributed to the combination of Hyaluronic Acid, Niacinamide, Vitamin C, and Vitamin E, per retailer descriptions -- this is a marketing bundling claim, not four separately clinically dosed treatments
- Brand-mislabeling caution: Sadoer products have repeatedly been found mislabeled as "Bioaqua" on some Bangladesh retailer listings in MedEasy's research across multiple batches. Buyers should confirm the packaging clearly shows the Sadoer brand name before purchase
- Claims caution: given the closely related Sadoer serum's Methylparaben content and the unverified/implausible percentage claims cited by some retailers for this SKU, MedEasy does not repeat these specific percentages as confirmed fact and cannot verify a "paraben-free" status for this exact product either way
