What Is Relfydess? The New Ready-to-Use Liquid Anti-Wrinkle Injection

Relfydess is the treatment my clients have been asking about most this year, and for good reason. It is the newest anti-wrinkle injection to reach New Zealand, and it does something no botulinum toxin before it has done: it arrives ready to use, as a purified liquid. If you have been reading about a "liquid Botox" or a new "botox alternative", Relfydess is almost certainly what you have seen.

Here is an honest, clinical look at what it is, how it differs from Botox and Dysport, and who it actually suits.

What Relfydess is

Relfydess (relabotulinumtoxinA) is a botulinum toxin type A made by Galderma, the company behind Dysport. Like every anti-wrinkle injection, it works by gently and temporarily relaxing the muscles that create dynamic lines, the creases that appear when you frown, squint, or raise your brows.

What sets it apart is the formulation. Traditional toxins arrive as a freeze-dried powder that has to be reconstituted, mixed with saline, before treatment. Relfydess is the first ready-to-use liquid of its kind. It is a purified toxin with a unique strain and, notably, no human or animal proteins in the formulation. Because it is not mixed on the day, the dose is precise and consistent from one appointment to the next.

How it compares to Botox and Dysport

All three products share the same active ingredient and the same purpose. The differences are in the detail.

  • Formulation. Botox and Dysport are reconstituted from powder. Relfydess is a ready-to-use liquid, which supports consistent, repeatable dosing.
  • Onset. In clinical studies, Relfydess showed a faster onset than earlier toxins, with some people noticing results within one to three days. Botox and Dysport typically begin to show from three to five days.
  • Longevity. Relfydess demonstrated a duration of up to six months for frown lines and crow's feet in trials. Botox and Dysport usually last three to four months, sometimes longer.

None of this makes Relfydess automatically "better". Botox and Dysport remain excellent, well-established treatments that I use every day. The right product depends on your muscle strength, the area being treated, how your skin has responded to toxin before, and what you want from the result.

Who Relfydess suits

Relfydess is worth discussing if you want a longer interval between treatments, if you have found earlier toxins wear off sooner than you would like, or if you simply want the most current option available. It treats the same areas as any anti-wrinkle injection: frown lines, crow's feet, forehead lines, and more.

As with all toxin, it is not for everyone. Relfydess is a prescription medicine, so suitability is assessed in a consultation, and it is not appropriate during pregnancy or breastfeeding, or for certain medical conditions. Your nurse will talk you through whether it fits your face and your history.

The best results rarely come from a single treatment. These are the two we reach for most often alongside it, and the reason each one earns its place in your plan.

Volnewmer RF Skin Tightening

South Island Exclusive

The only Volnewmer in the South Island

Volnewmer is the only monopolar RF skin-tightening device in the South Island. We use it for skin laxity, fine lines, and overall textural tone. It is the skin-quality envelope around most of the other work we do, and worth a conversation if skin tightening is on your mind.

Lift the SMAS layer, not just the surface

Ultraformer MPT is the latest generation of HIFU technology. It targets the SMAS layer, the same plane addressed in a surgical facelift, with focused ultrasound. The result is a non-surgical lift that pairs naturally with RF skin tightening and with injectables.
