"I had a fantastic skin needling treatment yesterday. I was really nervous, it was my first time. I was greeted so warmly but the staff, who were friendly, knowledgeable and very experienced. Not only did they patiently answer my hundreds of questions, they were so kind and patient. I felt very at ease, they continued to check how I was feeling and talked me through the process as they were performing the treatment. If you are looking for a treatment with professionals who actually care, You by Sia is fantastic."

"I've been a loyal client of You By Sia for over a decade and selfishly wanted to keep this gem to myself! As someone with brown skin, finding the right laser treatment has always been a challenge. But Sia and her team are the only ones I've trusted with my skin. Their deep understanding of how to treat and care for diverse skin tones has made all the difference."

"I have been a client of You by Sia for at least 9 years and trust the guidance from the team of professionals trained and cared for by Sia completely. I travel across town to be treated there because I know that with the team there, they are up front, honest and really take care of my needs."

"From start to finish my appointments at You by Sia were wonderful. I was always greeted by Nicole's smiles! Donna was fantastic with her description of my treatment and I am so happy with the outcome. The salon is always spotless and so easy to get to. Would 11/10 recommend You by SIA, thank you!"

"I have just had the most amazing results on a problem area that I didn't really think could be treated. Julie was most efficient, pleasant and always explained the process as we went along. This made me feel confident that I was in good hands. A wonderful experience all round."

- 01
You catch yourself in the mirror and barely recognise the woman looking back, new lines, pigment, dullness, redness that wasn't there a year ago.
- 02
You've quietly spent $1,000+ this year on serums, facials and trending treatments, and your skin still doesn't look the way you want it to.
- 03
You've been to other clinics, but no one ever gave you a real plan. Just a treatment, a product, and a vague "see you in six weeks."
- 04
You don't want fillers or anything that makes you look "done." You just want to look like yourself again, rested, clear, confident.
- 05
You're starting to wonder if this is just what skin in your 30s, 40s and 50s looks like now. (It absolutely isn't.)
The honest truth
Does this sound familiar?
If you nod at three of these, the Skin Diagnostic was built for you.

Meet Sia
Years of doing this properly.
I'm Sia, qualified dermal therapist and founder of You By Sia. I've built this clinic, and the team inside it, around women who feel exactly the way you do right now: tired of guessing, sick of being upsold, quietly wondering if anything will actually work.
Our philosophy is simple. Our clinicians won't sell you a treatment you don't need. They'll show you what your skin is actually doing, explain it in plain English, and build you a plan you can stick to. No pressure. No fluff. No injectables unless you genuinely want them.
"They genuinely care, and they actually know what they're talking about."

The difference
We don't guess.
We look.
Most clinics glance at your skin and recommend a treatment. We use the Observ® clinical-grade skin scanner, the same technology used by leading dermatology clinics, to reveal what your eyes cannot see.
Sun damage forming beneath the surface. The real cause of your redness. Hidden congestion. Early pigment. Your hydration levels, your barrier function, the structure of your skin itself.
You'll see your own skin on the screen. You'll understand it for the first time. And only then will we talk about what to do next.
Your hour with us
Step by step.
One hour, three moments. Calm. Private. No upsell at the door.
- 00–10 Minutes
Settle in.
A warm welcome, a glass of water, and a real conversation about what's been bothering you and what you've already tried.
- 10–25 Minutes
The Observ® skin scan.
Painless, no downtime. We capture a full picture of your skin, surface and deep, and walk you through what we see, together.
- 25–60 Minutes
Your diagnosis & plan.
Your clinician explains what's actually driving your concerns in plain English, and presents your personalised 12-week plan. No jargon. No pressure.

About the investment
$100 is the cheapest thing
you'll spend on your skin this year.
Think about what's already on your bathroom shelf. The serum that didn't work. The cream the influencer swore by. The peel you booked once and never followed up.
For $100, fully redeemable, you finally find out what's actually going on and stop spending on the wrong things. That's not a cost. It's the end of the wasting.

What you're probably thinking
The questions running through your head.
Read by hundreds of women before they booked. We answer them honestly.
"I've already had a consult somewhere else. Why can't I just book a treatment directly?"
Because someone else's plan, on someone else's machine, is not your plan. Every clinic reads skin differently, uses different products, recommends different protocols. Before we put hands or technology on your skin, we need to actually see it on the Observ® scanner, hear your full history, and build a plan we can stand behind. The diagnostic isn't a hurdle, it's the only way we'll treat you. You can absolutely book a treatment afterwards. Most women do, on the same day.
"I'm scared of looking fake or overdone. I want results, but not injectables."
Then you're exactly who we built this clinic for. We do not push, recommend, or sell injectables in your diagnostic. Full stop. Our entire approach is about restoring your skin's health, clarity, hydration, tone, texture, so you look like a more rested version of yourself, not a different person. The women in our reviews don't look 'done.' They look like themselves, on their best day.
"I've wasted so much money on products and treatments that didn't work. How is this any different?"
Because we don't guess. Most of that money got wasted because someone recommended a product or treatment without ever truly looking at your skin. The Observ® scan shows us exactly what's happening, beneath the surface, and we build your 12-week plan from that, not from a sales sheet. Your $100 is fully redeemable, so even the diagnostic fee comes back to you in product or treatment. You stop guessing, today.

A note on availability
Our clinicians see a handful of new
diagnostic clients each week.
Because every diagnostic is a full hour, one-on-one, we cap new-client appointments to protect the time we give to each woman who walks in.
The $100 new-client price is currently open. When the diagnostic calendar fills for the month, this page closes and the standard $230 fee returns.
If your skin has been on your mind for months, this is the week to stop thinking about it.
This week
7
new diagnostic appointments remaining at the $100 new-client price.
After
$230 standard fee
Same hour, standard price.
Our promise to you
Walk in curious.
Walk out clear.
You will never be pressured to book a treatment, buy a product, or commit to anything on the day. The scan is painless. The conversation is private.
If you decide we're not the right fit, you'll still leave with a written plan, your skin report emailed to you, and the clearest understanding of your skin you've ever had. Your $100 will have been the best money you've spent on yourself in months.

Before you book
Questions, answered.
Where are you located?+
We're at Shop 8/4-12 Waverley St, Bondi Junction NSW 2022. Easy to reach from anywhere in the Eastern Suburbs, with parking and transport nearby. Call us on (02) 8806 0765 or full directions are sent through with your booking confirmation.
Will I be pressured to buy anything on the day?+
No. Ever. Your diagnostic is about clarity, not closing a sale. You take your plan home, think about it, and decide in your own time. We genuinely mean it.
Is the Observ® skin scan painful or invasive?+
Not at all. It's a non-contact imaging scan. No needles, no downtime, no redness. You can return to work straight after.
Do I really get my $100 back?+
Yes. Your $100 is fully redeemable against any treatment or homecare product on the day of your appointment.
What if I don't know what's wrong with my skin?+
That's exactly what the diagnostic is for. Most women come in not knowing, and leave understanding their skin for the first time, often after years of guessing.
