Check a product free →In Bangladesh you’ll see skincare advertised as “first copy,” “master copy,” “1:1,” or “replica.” Sellers use these words to sound premium. The truth: they are all counterfeit. Here’s the breakdown.
The terms decoded
- Original / authentic — genuinely made by the brand, imported through a documented supply chain. The only safe option.
- First copy / master copy / 1:1 — a counterfeit designed to look as close to the original as possible. Still fake, still unregulated.
- Replica (counterfeit) — a copy of the packaging and name; the formula inside is unknown.
- Refill / decanted — sold loose or repackaged; you cannot verify what’s inside.
Why “first copy” is dangerous, not a bargain
A first-copy cream is made in an unregulated facility with unknown ingredients. Lab tests of Bangladeshi counterfeits have found mercury, steroids and bleach. The packaging may look identical, but your skin reacts to the *formula*, not the box. (See mercury dangers and banned products.)
Note: a genuine “dupe” (an affordable product with a *similar formula* sold honestly under its own brand) is different and fine — the problem is counterfeits pretending to be a brand they’re not.
