Many people carry a skin concern for years before they ask about it. Sun damage and scarring on the back are common examples, particularly after lesions have been removed.

Sisä makes that first conversation easier. We start with an assessment: what is in the skin, how it has changed over time, and which technology suits it. Sun damage and scar texture are different concerns, so they are assessed and planned separately.

At Sisä, that can include IPL and the Alma Hybrid.

Any new or changing skin lesion should be checked by a doctor before cosmetic treatment. All cosmetic procedures carry risk, and results vary between individuals.

Spring is the right time to think about sun damage and pigmentation, and here's the clinical reason why.

Lumecca IPL is an intense pulsed light treatment that targets pigmentation, sun damage, age spots, freckles, visible redness and vascular concerns, helping support a clearer, more even complexion. It works by delivering broad spectrum light that's absorbed by pigment and visible vessels in the skin, triggering a controlled response that your body then clears over the following days.

The reason spring matters is timing. IPL needs skin that hasn't had recent sun exposure, and diligent SPF afterwards, so treating now, before the intense summer sun, sets you up properly rather than trying to squeeze it in mid-summer.

The facts:

✨ Treats: pigmentation, sun damage, age spots, freckles, redness and visible vessels on the face, décolletage and body

🗓 Sessions: some improvement is often visible after one session, with three sessions spaced four weeks apart typically recommended for optimal results

⏳ Downtime: minimal, usually around 30 minutes in clinic, with any temporary redness or swelling generally settling within a day or two

📈 Results: a clearer, more even looking complexion as your skin renews

💰 Investment: full face from $400, spot treatment from $99, with packages available

Every treatment begins with a consultation with a Registered Nurse to confirm your skin is suitable.

Individual results vary. A thorough skin and medical assessment is required prior to treatment to confirm suitability.

Behind the chair..

I've been a nurse for over fourteen years. Long before aesthetics, I was caring for people in some of the most demanding areas of healthcare, orthopaedic surgery, then years in oncology as a Clinical Nurse Specialist, walking alongside patients through chemotherapy and their hardest days.

I completed a Master of Clinical Nursing and a Graduate Certificate in Oncology and Haematology, then stepped into hospital leadership as a Clinical Services Manager and in Quality and Infection Control, preparing a private hospital for national accreditation.

Everything I do now is built from that. Aesthetics wasn't a change of direction for me, it was the natural next step, a place to bring more than a decade of clinical depth, judgement and genuine care to a different kind of room. The rigour, standards and passion is the same. The duty to the person in the chair is exactly the same.

That's the difference a true clinical background makes, and it's the foundation Sisä is built on. Considered care from someone who has spent a career earning the right to be trusted with it.

I don't take that lightly, and neither does my team.

Warmly,
Chelsea Hyett, RN

Ever wondered what actually causes deep lines and wrinkles?

It comes down to a few things happening at once. Over time your skin produces less collagen and elastin, the proteins that keep it firm and springy, so it becomes thinner and less able to bounce back.

Years of repeated facial movements, like frowning, squinting and smiling, gradually etch lines into the areas that move most.

Sun exposure speeds the whole process up by breaking down collagen faster, which is why so much of how our skin ages comes down to UV over a lifetime.

Add in the natural loss of facial volume and fat as we age, and skin that once sat smooth and supported starts to fold and crease.

The good news is that understanding why lines form is what makes them treatable. There are genuinely effective options depending on what's driving yours, and the right approach is different for everyone.

That's a conversation best had in person. Book a consultation with one of our Registered Nurses via the link in bio and we'll talk through what's right for you.

Sisä Series: Injectable Peptides

We’re starting at the beginning.

🧬 Peptides are short chains of amino acids that act as messengers in the body, signalling cells to do things like produce collagen or repair tissue.

The word itself tells you very little, because what matters is which peptide it is and how it enters your body.

💧 The peptides in your skincare are topical and regulated as cosmetics.

💉 Injectable peptides enter your whole system and are regulated as medicines, and most of the ones sold online are unapproved, meaning no one has verified how they are made, whether they are sterile, or what is actually inside the vial.

Our position as a nurse-led clinic is simple: anything going into your body should be prescribed, quality controlled, and administered by a qualified professional who has assessed you first.

This week we’re breaking the whole trend down, including the case that started it.
