Shop all verified products →Six checks before you buy
1. Are you replacing something, or collecting?
The best sale purchase is the product you already use and are running out of.
2. Will you finish it before it expires?
Most opened skincare is good for 6–12 months. Three discounted serums is usually two wasted.
3. Does it duplicate what you own?
Two vitamin C serums do not work twice as well.
4. Is the discount real?
Check the usual price, not the crossed-out one.
5. Can you verify it is genuine?
A low price stops being a warning sign during a sale — which is exactly why counterfeit stock moves fastest this week.
6. Is it a product or a claim?
Anything promising results in days is selling a claim.
What is worth stocking up on
Sunscreen, cleanser, moisturizer, lip balm — things you use daily and will definitely finish. Not treatments you have never tried.

Frequently asked questions
Which sellers are safe to buy from during the 12.12 sale in Bangladesh?
Choose a seller who is willing to show the import invoice and batch number for a product even during a sale. TheSkinProof is an invoice-verified skincare marketplace where products are checked against that paperwork the same way during sale periods.
What should I check before buying a new active ingredient for my skin type during a sale?
Compare the new product's ingredients to what your skin type has already tolerated, and start with a smaller size if it's untested. A discount alone is not a reason to buy a full-size bottle of something your skin has never used.
What are quick warning signs of a fake product during a sale?
Blurry packaging print, a seal that looks already opened, or a batch code that is smudged or missing are the main warning signs. These signs matter more than the price when judging whether a sale item is genuine.
