Relfydess at Six Months: What Our Patients Really Think

When a new wrinkle-relaxing treatment comes to market, it often generates a lot of buzz but at McKeown Medical, we prefer evidence over hype.

Although all of these new drugs come to market with clinical trial evidence to support the manufacturing claims, we know that pharmaceutical companies often have a way of getting trials to say what they want them to say. What we are really interested in is what happens in the real world, and that’s what we wanted to find out.

Around six months ago, we began offering Relfydess, a next-generation botulinum toxin that promised faster onset, longer duration, and a smoother aesthetic finish compared to traditional products like Botox® and Azzalure®. To understand whether these claims translate into real-world results, we conducted a structured patient satisfaction survey: first shortly after we introduced the product to assess the short term impact, and again nearly six months later. The goal was to find out whether patients genuinely noticed a difference in how Relfydess works and lasts compared to their usual toxin treatment.

The Background: Early Impressions

When we first introduced Relfydess earlier this year, initial feedback from our patients was promising. Many reported that their results appeared to take effect slightly sooner than they were used to and described a particularly “crisp” or “polished” look to the final result.

The main drawback at that early stage? The injections themselves were more uncomfortable than those from conventional toxin formulations. This is consistent with what we expected based on the product’s formulation, which has a different pH and lacks certain buffering ingredients used in traditional toxins.

Encouraged by these early impressions, we wanted to assess whether these perceived benefits held true over time. You can read the full early results here.

The Six-Month Follow-Up Survey

We have now approached the same patients who were treated in the first month of us offering Relfydess and 62 patients responded, all of whom had previously used other botulinum toxins before switching to Relfydess. We asked three simple questions:

  1. Did you feel that Relfydess kicked in faster, slower, or about the same as your previous toxin?
  2. How did you feel about the way Relfydess looked compared with your previous toxin?
  3. How do you feel the results have lasted over time compared with your previous toxin?

Here’s what our patients said.

1. Onset: Did Relfydess Kick In Faster?

  • 69% felt Relfydess kicked in faster than their previous toxin
  • 31% said it was about the same
  • 0% thought their previous toxin kicked in faster

This result confirms what many patients reported early on: a noticeably quicker onset. For busy patients who like to see results promptly before a special event, this may be a meaningful advantage.

2. Appearance: Did It Look Better?

  • 52% felt Relfydess looked better than their previous toxin
  • 35% thought it looked about the same
  • 13% preferred the look they achieved with previous treatments

More than half of patients preferred the aesthetic finish achieved with Relfydess. The most common description was a “refined” or “cleaner” look, suggesting subtle qualitative differences in how the product diffuses in facial muscles and how movement settles over time.

3. Longevity: Did It Last Longer?

  • 56% felt Relfydess lasted longer
  • 38% thought it lasted about the same
  • 6% felt their previous toxin lasted longer

Durability is one of the key areas where Relfydess claims superiority, and our data seems to support that — at least modestly. Over half of patients felt their results lasted longer, with only a small minority perceiving shorter duration.

Interpreting the Results

These findings build on our earlier short-term impressions and suggest that Relfydess delivers tangible advantages for a majority of patients, particularly in terms of faster onset and potentially improved longevity. This is not in manufacturer sponsored clinical trials but in a real world setting.

However, as with all aesthetic treatments, results vary between individuals. Those who already achieved excellent outcomes with their previous toxin may find the differences subtle. For others, especially those who had started to feel their results weren’t lasting as long as they once did, Relfydess appears to offer a welcome improvement.

We also continue to monitor the issue of injection discomfort. While most patients find it tolerable, we’ve adapted our injection technique by adding in a small amount of local anaesthetic to help reduce stinging and will continue refining this as experience grows.

What This Means for Our Patients

The takeaway is clear: Relfydess is not simply a marketing gimmick – it appears to offer real, patient-perceived benefits. That said, it’s not necessarily the right choice for everyone. Our team will continue to offer a range of botulinum toxin options, tailoring each treatment to your goals, comfort level, and previous experiences.

If you’re curious about whether Relfydess might be a good option for you, we’d encourage you to book a consultation with one of our clinicians to discuss your aesthetic goals in more detail.

Aesthetic interventions are never far from the headlines and this week the media have been focused on comments made by the make up artist Bobbi Brown about her view of cosmetic procedures. I was on BBC Radio Scotland today talking about the issue. 

My own view is that we should all age in the way we feel comfortable with - if you are happy with grey hair and wrinkles, then I absolutely admire you just as much as  I admire those who feel differently and want a little help to keep the signs of ageing at bay. There is no right and wrong and there is no room for moral superiority. Just you be you!

We often talk about the deep plane facelift being the gold standard technique for facelift, and we’re proud to have the talented @bramhallplasticsurgery performing it in the clinic. 

Here’s Russell explaining how the deep plane facelift offers longer lasting and more natural results than other techniques. By lifting and repositioning the deeper facial structures rather than just tightening the skin, this advanced approach creates a result that looks natural, moves naturally, and continues to age beautifully over time.

If you have any questions about the deep plane facelift just send us a message, or you can see more about the procedure at the link in our profile.

This patient had deep lines and folds in her face which she wanted to address as naturally as possible, so went for our signature volumetric facelift - a fully non-surgical approach but can have significant results.

With this, we want to restore natural lift, structure and definition to her face and by carefully rebuilding volume where it’s been lost, we softened her folds and lines while maintaining a completely natural expression.

The patient is delighted is really pleased with her result so far - what do you think?
Here's another fabulous result from our amazing consultant vascular surgeon, Dr Alex Vesey. 

This patient was bothered by visible varicose veins around her knee. After treatment with foam sclerotherapy the veins have been cleared, leaving behind smoother, and healthier-looking skin.
