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.

We’ve always loved what technology can allow us to do with skin, and Ultraformer III has been part of our clinic for a long time. 🤍
So we thought we’d answer some of the things we’re asked most often.
Who may be suitable?
How long does treatment take?
What is the downtime like?
How long can the effects last?
Everyone’s skin is different, which is why we look at your skin, structure and individual goals before deciding whether a particular technology may be appropriate for you.
Swipe through for a little more on Ultraformer III.
We’re particularly excited to be sharing this now because something new is coming to the clinic very soon.
An upgraded generation of this technology is on its way, and we genuinely cannot wait to show you more.
Stay tuned 🤍

A new chapter in one of our favourite technologies is coming to Dr Cosima Medispa.
For years, Ultraformer III has been part of our approach to non-surgical skin tightening and contouring.
Using focused ultrasound energy, treatments can be customised across different areas of the face, neck and body, depending on your individual assessment and treatment goals.
What we love most is being able to take a considered approach to skin ageing. Looking at structure, firmness and the changes happening beneath the surface, then deciding what technology may be appropriate for you.
And now, we’re getting ready for what comes next.
We are SO excited to introduce the upgraded generation of this technology to the clinic, and we’ll be showing you much more very soon. 🤍
New technology. More possibilities. The same personalised approach to your skin.
Stay tuned for the reveal.

Some appointments feel different on a Saturday.
Saturdays at our Bondi Junction clinic are with Nurse Anika, part of our clinical team working alongside Dr Cosima on patient care.
Anika sees patients for consultations and treatments across the week. Saturday appointments offer greater flexibility for patients with busy weekday schedules.
If mid-week appointments have never quite worked for you, this might be the one that does.
Want to know more about Saturday appointments with Anika? Send us a message or call (02) 9362 1728.

I've always been a little obsessed with technology.
Not because something is new, but because I'm constantly asking whether there's a better way to support the skin and give my patients more considered options.
Over the years, that curiosity has led me to research technologies from around the world and be very selective about what I bring into the clinic.
And I've been researching again...
Something new is on its way to Dr Cosima Medispa.
It's an exciting upgrade for the clinic, and I genuinely can't wait to share more with you very soon.
Watch this space 🤍

Your skin doesn’t necessarily reflect the age on your passport.
Living in Australia, we’re exposed to a lot of sun, and that cumulative exposure can influence how our skin changes over time.
That’s why I like to start by actually looking at the skin properly.
A Comprehensive Skin Consultation gives us the opportunity to assess what’s happening with your skin, understand your concerns and work out whether there’s anything worth addressing.
Because sometimes the best place to start is simply understanding your skin better.
For those who find weekdays a little tricky, Saturday consultations are available with Nurse Anika at our Bondi Junction clinic.

Your skin is constantly changing, and sometimes those changes are easier to see than understand.
Texture, tone, redness and changes in overall skin quality can all form part of the bigger picture.
A closer assessment helps us understand what we’re seeing before deciding what your skin may need next.
At Dr Cosima Medispa in Bondi Junction, our approach begins with looking closely at your skin, listening to your concerns and creating a personalised plan based on what we find.
Because your next treatment shouldn’t begin with guesswork. It should begin with understanding your skin.

Repair. Regenerate. Realign.
This is how we approach skin ageing. We look at the face as a whole, rather than focusing on one area at a time.
Repair focuses on visible skin quality.
Regenerate supports the deeper structures of the skin over time.
Realign considers proportion, volume and how each feature works together to create facial harmony.
We often see patients who have had the same area treated repeatedly, while areas such as the temples, perioral region, neck or décolletage have received little attention.
Each treatment may have been performed well, yet the overall result can still feel out of balance.
Our approach starts with understanding the whole picture. Your skin. Your facial proportions. Your concerns. Your goals.
From there, we can create a personalised plan designed around you.
