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.

Frequently asked questions
What is the difference between original and first-copy skincare?
Original is genuinely made by the brand and imported through a documented supply chain. “First copy,” “master copy,” “1:1” and “replica” are all counterfeits made in unregulated facilities with unknown ingredients — not safe, regardless of how the packaging looks.
Is first-copy skincare safe to use?
No. First-copy creams are unregulated; lab tests of Bangladeshi counterfeits have found mercury, steroids and bleach. Your skin reacts to the formula, not the box.
How can I be sure I am getting the original?
Buy from TheSkinProof, which sells only originals — each invoice-verified and batch-checked, with a 2× money-back guarantee if any product is ever proven counterfeit.
If a seller openly calls a product "master copy" or "1:1", could it still be genuine?
No, terms like "master copy" or "1:1" are the seller's own admission that the product is a counterfeit made to look like the original. However polished the packaging looks, the formula still comes from an unregulated factory.
Where should I buy to be sure I'm getting the original, not a first copy?
Buy from a seller who can show the importer invoice and batch number for the product. TheSkinProof doesn't sell first-copy or repackaged items; every product is invoice-verified.
