Direct answer: Buy cosmetics from the brand's own store or an authorized retailer, treat prices far below retail as the loudest warning, and inspect batch codes, seals, and print quality before first use. Counterfeit cosmetics are the one fake where the product itself, not just the price, can hurt you.
A counterfeit handbag disappoints. A counterfeit foundation can contain ingredients nobody chose, made in facilities nobody inspected, and reports over the years have found everything from bacterial contamination to lead and other heavy metals in seized fake cosmetics. The category attracts counterfeiters because the products are small, pricey, fast moving, and bought on emotion and trend cycles.
The good news is that cosmetics are hard to fake perfectly, and the tells concentrate in the same places: the seller, the price, the packaging, and the codes. This post works through each check in the order you would naturally meet them, from listing to unboxing.
Start where the risk starts: who is selling. The brand's own store, its listed authorized retailers, and established beauty chains with direct brand relationships are the safe channel. Marketplace listings from rotating third party sellers, social media shops with no business identity, and auction lots of mixed luxury cosmetics are where seized fakes overwhelmingly surface.
Price is the second filter and it rarely lies. Cosmetics margins are structured; a current, popular product at half of retail or less, outside a known retailer's sale event, is almost never a legitimate gray market bargain. Counterfeiters price to tempt, not to match, and the discount is the bait. When a deal looks impossible for a product that never goes on sale, believe the arithmetic.
Compare against a known genuine unit or the brand's official product photos. Counterfeit packaging betrays itself in small manufacturing economics: slightly off brand colors, fonts that are close but not exact, spelling slips, flimsy cartons, and print that smears or misaligns at the edges. Seals matter too: genuine products in this category are typically sealed or tamper evident, and a missing or reglued seal is grounds to stop.
Use the batch or lot code. Most legitimate cosmetics carry a printed or stamped code that ties the unit to a production run, and many brands will confirm a code through customer service. Fakes often copy one real code across thousands of units, print it in the wrong place or format, or omit it. If the texture, smell, or color of the product itself differs from a unit you have used before, trust that over the packaging: stop using it.
Do not test it on your face to decide. Photograph the packaging and codes, keep the receipt and listing screenshots, and report the seller to the platform with the evidence; platforms act faster on documented reports. Request a refund through the payment channel rather than negotiating with the seller, and tell the brand's anti counterfeit contact, since brands compile seller patterns across reports.
If you have already used a product you now suspect, watch for reactions over the following days and see a clinician if irritation, swelling, or infection signs appear, bringing the product with you. Then replace from the safe channel. The small premium of authorized retail is, in this category, partly a payment for a supply chain you can trust against your skin.

Seized fakes have repeatedly tested positive for contamination and harmful substances, because they are made without ingredient control or hygiene standards. Treat them as a safety issue, not a quality disappointment.
A code helps but is not proof, since counterfeiters copy real codes. Use it as one check among several: seller, price, packaging quality, seal, and the product's look and smell together make the call.
Established discount retailers selling genuine overstock are a different channel from anonymous marketplace sellers. The risk markers are the seller's identity and the price gap, not the word discount itself.
That proves nothing either way; copied photos are standard practice for fake listings. Judge by the seller's history, the price, and the physical product when it arrives.
