FAKE VS ORIGINAL
SERUM.
1. Active Ingredient Concentration
Genuine serums like Vitamin C or Niacinamide clearly state the active percentage on the packaging (e.g. "10% Niacinamide"). Fakes rarely list exact percentages, or they list them but the formula is diluted far below the claimed amount.
2. Texture and Absorption
Authentic serums have a consistent, lightweight texture designed for rapid absorption. Counterfeit serums may feel sticky, too oily, or leave a film because they are made with cheap filler oils instead of active concentrates.
3. Oxidation and Color
Real Vitamin C serums are typically a pale yellow when fresh. Fakes may be completely colorless (no ascorbic acid) or pre-oxidized dark orange. Always check the expected color for the specific serum you're buying.
4. Hologram and Seal
Premium serum brands like The Ordinary, Skinceuticals, or Paula's Choice include tamper-evident seals and holograms on the box. If the seal is missing or looks reprinted, do not use the product.
5. Results Timeline
Authentic serums deliver visible results within the expected timeframe (e.g. skin brightening in 4–6 weeks). If a product claims instant dramatic results or produces no change whatsoever, it's likely counterfeit or completely inactive.
