Most counterfeit categories cheat you out of money or quality. Sunscreen cheats you out of protection you will not know you missed until the burn, or worse, until years of assumed protection turn out to have been theater.
It is also a category where gray market and counterfeit blur: diverted stock, expired product relabeled, and outright fakes all circulate, and all three defeat the SPF on the front.
A legitimate SPF claim rests on testing of that formulation, manufactured to drug standards, with active ingredients at stated concentrations, evenly dispersed and stable through the product's shelf life. Every step is invisible. A counterfeiter copying the artwork inherits the number for free, while the emulsion inside may separate, under dose the filters, or omit them, and no consumer test short of a laboratory can tell from the texture, because a pleasant lotion and a protective sunscreen feel identical on skin.
Expiry is the quieter version. UV filters degrade, and sunscreen past its date, or stored in heat through a diverted supply chain, delivers less than the label. Counterfeit operations have been caught relabeling expired stock, which is why a suspiciously cheap current season bottle deserves the same skepticism as a fake.
Buy sunscreen from the brand, pharmacies, and established retailers, where the drug supply chain is documented. On marketplaces, prefer the brand's own storefront over third party sellers, and treat imported versions of a domestic product as a research task: formulations differ by country because regulations differ, and a foreign version is not automatically the product the reviews described.
Check the packaging against the brand's current version, the drug facts panel for US product, batch and expiry printing quality, and the seal. Tube and pump products add one more check: counterfeit packaging often gets the container subtly wrong, a cap that fits poorly, a crimp pattern unlike the genuine tube, because the packaging machinery, not the lotion, is the expensive part to copy faithfully. Then do the simple thing nobody does: register the purchase source in your head. If a beach trip produces burns through fresh sunscreen applied properly, suspect the bottle, replace it from a pharmacy, and report the listing with the batch code photographed.
Regulators treat counterfeit drug products as a priority category, and marketplaces remove sunscreen listings on evidence that would be overkill for a t shirt: batch code mismatches, packaging divergence, test purchase analysis. Brands monitor this category hard because the liability story writes itself. Buyer reports that include batch codes and purchase details genuinely move; vague complaints about texture do not.

You usually cannot tell from the lotion itself. Judge the channel: brand storefronts and pharmacies over unknown marketplace sellers, current packaging and crisp batch and expiry printing, and prices inside the normal retail band.
An expired genuine product likely retains partial protection, while a counterfeit may have none. Neither is a plan. Replace suspect sunscreen; it is one of the cheapest forms of insurance you will ever buy.
Not necessarily. Sunscreen formulas differ by country because approval systems differ, and some foreign versions are sought after. The risk is unverifiable sellers; buy imports from established retailers who stand behind the product.
Order details, the seller, clear photos of the packaging and drug facts panel, and the batch and expiry codes. Those details let the platform and brand match your unit against production records.
