Quick answer
The biggest sale of the year is also the year's best cover for counterfeit stock. Buy what you already use, and verify it.
Want the authentic one? Every product on TheSkinProof is invoice-verified.
Shop all verified products →1. Restock what you already use
Restock the things you use daily and will certainly finish: sunscreen, cleanser, moisturizer, lip balm. These are the purchases you never regret at a discount.
2. Do not buy an untried treatment for the discount
A treatment you have never tried, because it is 70% off. If it does not suit your skin, the discount saved you nothing — and a full-size bottle of the wrong active is a month of irritation.
3. A low price stops being a warning during a sale
For most of the year an unusually low price is itself a warning. On 11.11 everything is discounted, so that signal disappears. This is precisely why counterfeit stock moves fastest during sale week.
Check before you buy, not after. By the time texture or smell seems wrong, you have used it.
Quick checks
1. Batch code traceable to an importer record

3. Seller does not list every premium brand at a deep discount
4. Outer packaging present — "imported, no box" usually means no import trail
