Smoother, more even texture.
Softens fibrous tissue to refine the look of scars, stretch marks and rough patches.
PB Serum is an enzyme-based treatment that works with your skin’s own biology to remodel tissue, refine texture and restore firmness — a genuinely regenerative approach rather than a quick surface fix.
Hannah is a qualified nurse with over ten years of clinical experience and advanced training in aesthetic medicine. Every treatment is assessed properly, tailored to your skin, and delivered to medical standards — with honest advice and natural-looking results at the centre of it all.
What is PB Serum and how does it work?
PB Serum uses recombinant enzymes — purified, medical-grade proteins — to target specific tissues beneath the skin. In plain terms, these enzymes act as tiny tools that break down what your skin no longer needs and encourage it to rebuild what it does.
The two most commonly used enzymes are collagenase and hyaluronidase. Collagenase softens and reorganises hardened or fibrous tissue — the kind found in scars, stretch marks and stubborn cellulite. Hyaluronidase gently breaks down excess or unevenly placed hyaluronic acid, which helps refine areas of puffiness or overfilled tissue.
Here’s what makes this different from a standard skin treatment. PB Serum doesn’t just sit on the surface or add volume. It signals your skin to remodel itself — clearing old, disorganised tissue so healthier, better-structured tissue can take its place.
The result is smoother, firmer, more even skin that looks natural because the improvement comes from within.
How PB Serum works with your skin
The science is refreshingly logical. Your skin holds its shape thanks to a network of proteins — mainly collagen and hyaluronic acid. Over time, that network can become hardened, uneven or disorganised through ageing, scarring or fatty and fibrous build-up.
PB Serum introduces enzymes that gently break down the tissue causing the problem. Once the old structure is cleared, your skin responds the way it’s designed to — by producing fresh, well-organised collagen in its place.
You’re not masking the issue. You’re prompting your skin to rebuild itself properly.
That’s why results look natural and tend to improve over the following weeks. The change is structural, not superficial.
Benefits of PB Serum
PB Serum can be used on the face and body, and every treatment plan is tailored to your skin and your goals.
What to expect during your appointment
Your appointment starts with a thorough consultation. Hannah assesses the area, discusses your goals, and confirms whether PB Serum is the right treatment for you — with no assumptions and no rushing.
After that, the area is cleansed and a fine needle is used to place the enzyme solution precisely where it’s needed. Most people describe the sensation as a mild sting or pressure rather than genuine pain, and treatment usually takes 20 to 40 minutes depending on the area.
Post-treatment you may notice some redness, mild swelling or slight tenderness at the treated site. This is entirely normal — it’s a sign the enzymes are doing their work — and it typically settles within a few days.
Aftercare and results
Good aftercare protects your results. For the first 24 to 48 hours, keep the area clean, avoid heat treatments like saunas and hot baths, and skip strenuous exercise so your skin can settle.
Beyond that, two habits matter most: gentle hydration and daily SPF. Sun protection safeguards the new collagen you’re working to build.
Results build gradually. Because PB Serum encourages your skin to remodel itself, improvements continue over several weeks as fresh collagen forms. Most people need a short course of sessions, spaced a few weeks apart, for the best and longest-lasting outcome. Hannah will map out the right plan for you at your consultation.

Frequently Asked Questions
What is PB Serum used for?
PB Serum treats a range of concerns using enzymes that remodel tissue — including scars, stretch marks, cellulite, skin laxity and localised puffiness or fatty deposits. Hannah will confirm the right approach for your specific concern during your consultation.
Is PB Serum painful?
Not usually. The solution is placed with a fine needle, and most people describe a mild sting or pressure rather than real pain. Any discomfort is short-lived.
Is there any downtime?
Minimal. You may have some redness, mild swelling or tenderness for a few days, but most people return to normal activities straight away.
When will I see results?
Because PB Serum works by remodelling tissue, results build gradually over several weeks as your skin produces new collagen. Improvement continues after each session.
Is PB Serum safe?
Yes, when delivered by a qualified professional. The enzymes are purified and medical-grade, and Hannah’s clinical background and ACE membership mean every treatment is carried out to strict safety standards.
How much does PB Serum cost?
Pricing depends on the area treated and the number of sessions in your plan. Book a consultation for an accurate, personalised quote.
