Rejuran’s growing popularity has an unfortunate side effect: a rise in counterfeit and grey-market products. Fake Rejuran isn’t just a waste of money — it can be unsafe, since you have no guarantee of what’s inside the vial or how it was stored. This guide explains how to spot fake Rejuran so you can protect your skin, your health, and your investment.

Why Counterfeit Rejuran Is a Serious Problem
Genuine Rejuran is a polynucleotide (PN) product that must be manufactured to strict standards and kept in proper cold-chain storage. Counterfeit versions may contain unknown ingredients, incorrect concentrations, or contaminants. Injecting or applying an unverified product carries real risks, which is why authenticity matters as much as price. For background on safe cosmetic products, the U.S. Food and Drug Administration offers general guidance on cosmetic safety.
7 Ways to Spot Fake Rejuran
1. Check the Packaging and Print Quality
Authentic Rejuran packaging uses crisp, high-quality printing. Be suspicious of blurry text, faded colours, spelling errors, mismatched fonts, or flimsy boxes.
2. Verify the Batch Number and Expiry Date
Genuine products carry a clear batch (lot) number and a legible expiry date. Missing, smudged, or tampered-with codes are a major red flag.
3. Inspect the Holographic or Authenticity Seal
Many genuine products include security features such as holograms or QR codes. If a seal looks photocopied, peels off easily, or is absent, treat the product with caution.
4. Be Wary of Prices That Seem Too Good
Counterfeiters compete on price. If an offer is dramatically below the market rate, it is often fake. See our Rejuran price guide to understand realistic pricing.
5. Scrutinise the Seller
Buy only from reputable, transparent sources with clear contact details, return policies, and verifiable reviews. Anonymous social-media sellers and marketplaces are high-risk. Our guide on where to buy genuine Rejuran online covers this in depth.
6. Examine the Product Itself
The solution should look as described by the manufacturer. Unusual colour, cloudiness, particles, or a damaged vial seal all indicate the product may be fake or improperly stored.
7. Confirm Proper Storage and Shipping
Genuine Rejuran requires temperature-controlled handling. A trustworthy seller will explain how the product is stored and shipped. Vague or missing storage information is a warning sign.
