How to tell whether your filler is genuine — and why the brand matters less than the plan
Medical team, Nuance Clinic
Counterfeit and unlicensed filler is the biggest safety problem in aesthetic medicine, and İstanbul is not immune. This guide explains how to verify a product, what distinguishes premium ranges like Teosyal RHA, and why product choice should always follow the treatment plan.
Quick facts
- Ask to see the sealed syringe and the batch sticker, every time.
- RHA gels behave well in mobile areas like lips and the perioral region.
- Density should be matched to tissue, not to price.
- A good plan with a mid-range product beats a bad plan with a premium one.
What it is
- RHA stands for resilient hyaluronic acid: gels manufactured with minimal chemical modification so they behave more like natural tissue during movement.
- Different densities exist for fine lines (RHA 1/Redensity), medium folds (RHA 2/3) and deep structural support (RHA 4).
Who it suits
- Patients who want a soft, mobile result in expressive areas
- Perioral lines, lips, nasolabial folds, cheeks and chin
- Anyone who has previously found filler felt stiff or looked static

Questions about this treatment
Is Teosyal better than other brands?
It is excellent in mobile areas because of its resilience. In other indications another brand may be the better technical choice — that is a medical decision.
Do you show the product before use?
Always. The sealed syringe is opened in front of you and the batch number goes into your file.
How do I know a filler is genuine?
Sealed packaging, a traceable batch sticker, correct storage and a clinic willing to show you all of it.
