The Ordinary (by DECIEM) became famous for high-quality single actives at low prices — niacinamide, vitamin C, hyaluronic acid, AHA/BHA and more. Ironically, its low price makes counterfeits *more* tempting to produce, and a fake active is both ineffective and potentially unsafe. Here’s how to check. (For products to start with, see our The Ordinary guide.)
What genuine The Ordinary should have
- Minimal, precise labelling — the brand’s signature plain look, but with crisp, correctly-spelled text and the exact ingredient + % name.
- A matching batch code & expiry (verify a batch code).
- Correct dropper/pump and bottle — quality glass/plastic, proper seal.
- The expected texture/scent for that formula (e.g. the known “tingle” of certain actives — but not burning).
Biggest fake signals
1. Price even lower than The Ordinary’s already-low retail — a strong fake signal. (See why too cheap is fake.)
2. Print/label errors, wrong % notation, weak seal.
3. No checkable batch code or one that fails.
4. Anonymous Facebook-only sellers with no sourcing proof. (See how to identify fakes and Daraz & Facebook.)
Why it matters
A fake vitamin C or niacinamide with unknown contents won’t deliver results and could irritate or harm your skin. Genuine actives also degrade in heat, so storage matters too.

Before you buy: check authenticity, not price
Don’t chase the cheapest product — look for the authentic one. A cheap fake can damage your skin, and using nothing at all does less harm than using a counterfeit. But a high price doesn’t guarantee authenticity either — people overpay for fakes too. So judge by authenticity, not price.
TheSkinProof offers free authenticity verification. Message our Facebook page with the product and we’ll analyze it and tell you whether it’s real or fake — so it’s important to verify before you buy anything. Or simply buy from TheSkinProof, where every product is already invoice-verified with a 2× money-back guarantee.
