One of my favourite consultations starts with someone saying,

“I’m not really sure what I need.”

Perfect.

You’re not supposed to diagnose your own skin.

I’d much rather hear what you’ve noticed and what you would like to address.

Then I can look at the whole picture.

Skin quality. Structure. Proportion. Your treatment history. The neck and décolletage. Areas that may have been overlooked.

Sometimes what someone thought they needed isn’t where I would start at all.

That’s why I love the consultation process.

It gives us room to think before we treat.

So, what does an Ultraformer MPT appointment actually look like?

Since introducing MPT to the clinic, I’ve noticed the questions have shifted.

People understand the idea of focused ultrasound. What they really want to know is what happens when they’re actually in the treatment room.

How long should I allow?
Can I go back to my day afterwards?
Where can it be used?
And how do we decide what’s appropriate for my skin?

I’ve answered the questions I’m hearing most in today’s carousel.

Swipe through for the practical side of Ultraformer MPT.

And one thing worth remembering while you’re reading.

Your treatment plan should always start with an individual assessment.

Technology gives us options.

The consultation helps us decide which options make sense for you.

Aesthetic medicine has changed enormously since I started.

One of the shifts I find most exciting is the attention we’re now giving to the skin itself.

Collagen.
Texture.
Firmness.
Skin health.
And how all of those things change over time.

This is a big reason I became so interested in technology.

It’s also why I’m interested in having different options available rather than relying on one approach for everyone.

Ultraformer MPT and PRX-Plus are very different treatments, but both can be considered within a broader conversation about the skin.

For me, that conversation should always start with the individual sitting in front of us.

PRX-Plus is actually quite simple to describe.

It’s applied topically.

It’s massaged into the skin.

A session takes approximately 30 minutes.

There are no needles and no traditional peeling.

The more interesting conversation is where it may fit into your skin plan.

We may consider PRX-Plus when looking at concerns around tone, texture and firmness. The treatment frequency is also personalised according to your skin and individual goals.

This is why I always come back to assessment.

There are so many treatments available now. You shouldn’t have to work out which one you need before you walk through the door.

That’s our job to work through with you.

We’ve been talking a lot about technology lately, but there’s another new addition to the clinic I’ve been looking forward to sharing more about.

PRX-Plus.

This one takes a different approach.

PRX-Plus is a topical biostimulation treatment. It is massaged directly onto the skin rather than injected.

No needles. No traditional peeling. No planned downtime.

It may be considered as part of a personalised treatment plan for concerns around skin firmness, tone and texture.

And this is the part that interests me.

Over the years, skin quality has become such an important part of how I think about aesthetic medicine.

There’s so much more we can consider beyond one individual line or area.

PRX-Plus gives us another option to bring into that conversation.

My relationship with skin technology has changed enormously over the years.

When I first started in cosmetic medicine, I didn’t have nearly the same interest in skin that I do now.

Then I reached a point where I thought, okay, there has to be more we can look at here.

Collagen.
Skin quality.
Firmness.
Texture.

What’s happening beneath the surface.

That curiosity is what pushed me further into technology, and it’s still what drives a lot of the decisions I make in clinic now.

Ultraformer MPT is one of those technologies.

It gives us another option to consider when focused ultrasound is appropriate for someone’s skin, anatomy and treatment goals.

Not everyone needs the same thing.

That’s what keeps this work interesting.

Naturally, one of the first things people have been asking me is what has actually changed with Ultraformer MPT.

Quite a bit.

MPT is the newer generation of the Ultraformer technology we’ve been using in clinic.

The ultrasound energy can be delivered more efficiently and precisely, treatment sessions are faster, and the experience is more comfortable compared with our previous Ultraformer technology.

What hasn’t changed is how we decide to use it.

I’m not interested in using a technology simply because it’s new.

We look at your skin, anatomy and what you’d actually like to address. Then we decide where the technology may fit.

That part will always matter more to me than having the newest machine in the room.

A little while ago, we told you that the next generation of one of our favourite technologies was coming.

Now it’s here.

Ultraformer MPT has officially arrived at Dr Cosima Medispa.

After years of working with Ultraformer III, I was really interested to see what the upgraded generation could bring to the clinic.

MPT still uses focused ultrasound energy, with treatment customised according to the area being treated, your skin and your individual assessment.

What has changed is the technology itself.

The newer generation allows us to deliver energy more efficiently and with greater precision.

Treatment times are also faster, and the overall experience is more comfortable compared with our previous Ultraformer technology.

For me, that is where the excitement is.

New technology is only valuable when it adds something meaningful to the way we treat.

The approach remains the same.

We still look at your skin, structure, firmness and treatment goals first. Then we decide whether this technology has a place in your plan.

Ultraformer MPT is now available in clinic, and we’ll be sharing much more about it over the coming weeks.

We love treatments that work with the skin and fit easily into real life.

This patient completed four PRX-Plus treatments, one week apart.

PRX-Plus is a topical biostimulation treatment that is massaged directly onto the skin. No needles. No peeling. No significant downtime.

At Dr Cosima Medispa, we use PRX-Plus to support skin firmness, tone and texture, particularly for patients who want their skin to look fresher and healthier while still looking like themselves.

Each session with us also includes LED light therapy.

We always look at the skin as a whole and choose treatments that make sense for you. PRX-Plus can be used on its own or incorporated into a broader, personalised treatment plan.

Want to know whether PRX-Plus could be suitable for your skin?

Meet Natalie 🤍

There are some people who naturally make you feel looked after from the moment you meet them.

Natalie is one of those people.

She joins us as our Receptionist and PA after more than 15 years working in healthcare, bringing with her a wealth of experience in patient care and a Certificate III in Dental Assisting.

For me, the experience you have at Dr Cosima Medispa starts well before you sit down in the treatment room.

It’s the person who answers your call. The familiar face who welcomes you when you arrive. The little details that make you feel comfortable, remembered and genuinely cared for.

Natalie fits into that philosophy so beautifully.

She has always had a passion for beauty and self-care, so moving into aesthetics felt like a very natural progression. She’s also incredibly eager to learn, which you all know is something I LOVE.

Outside the clinic, you’ll probably find her planning her next trip, exploring a new city or spending time with her Labradoodle, Chuck 🐶

We’re so excited to have her with us.

Welcome to the team, Natalie 🤍

Please say hello when you’re next in the clinic.
