BIOSTIMULATORS & COLLAGEN STIMULATORS IN CARDIFF
Biostimulators are injectable treatments that encourage your skin to produce its own collagen and elastin, improving firmness, structure and skin quality gradually over the following weeks and months. At our clinic on 39 Charles Street in Cardiff city centre, we offer Sculptra, Radiesse, Juvelook, Julaine, Profhilo Structura, Sunekos, polynucleotides, NCTF 135 and exosomes, with treatments starting from £199. Injectable treatments are performed by GMC or NMC-registered medical professionals, and we see patients from across Cardiff and South Wales.
WHAT ARE BIOSTIMULATORS?
What are biostimulators?
Biostimulators represent the evolution of aesthetic medicine—treatments that don't just mask aging but actively reverse it by triggering your body's natural collagen and elastin production. Rather than adding temporary volume like traditional fillers, biostimulators work at the cellular level to rebuild your skin's architecture from within.
The result? Natural, gradual improvement that develops over weeks and months as your body produces new collagen. Results last significantly longer than hyaluronic acid fillers—typically 18-24 months—because you're creating your own tissue rather than relying on synthetic materials that eventually dissolve.
Collagen production slows from our mid-twenties and declines further with age, sun exposure and lifestyle. That loss shows up as thinner, less elastic skin, hollowing and softening of facial contours. Biostimulators aim to address that underlying change, so results look natural and develop gradually.
At Sebastian Rose Medical Aesthetics, we offer the most advanced biostimulator treatments available: Sculptra, Profhilo Structura, Sunekos, Juvelook, Poly-L-Lactic Acid, PDLLA, PDRN, Radiesse, polynucleotide-based collagen stimulators, and more. Each targets different concerns and areas, working to restore youthful structure, improve skin laxity, and deliver transformative results that look completely natural.
HOW DO BIOSTIMULATORS WORK?
Different biostimulators work in different ways, but they share the same goal: encouraging your skin to renew itself.
Hybrid biostimulators:
HArmonyCa
HArmonyCa combines both approaches in one syringe. Hyaluronic acid lifts the jawline and cheeks immediately, while calcium hydroxyapatite microspheres stimulate your own collagen over the following months. It's the only treatment here that gives you something on the day and keeps working afterwards.
Microsphere collagen stimulators:
Sculptra (poly-L-lactic acid) and Radiesse (calcium hydroxylapatite) contain tiny particles that act as a scaffold. Your body responds by producing new collagen around them, and the particles are gradually broken down over time. Radiesse also gives immediate structure from its gel.
Hyaluronic acid bio-remodellers:
Profhilo, Profhilo Structura and Juvelook combine hyaluronic acid with ingredients that support collagen and elastin production, improving hydration and firmness. Juvelook also contains PDLLA microspheres for longer-term collagen stimulation.
Amino acid and mesotherapy treatments:
Sunekos combines hyaluronic acid with six amino acids to support collagen and elastin, while NCTF 135 delivers a blend of vitamins, amino acids and antioxidants into the skin.
Regenerative treatments:
Polynucleotides such as Plinest, Rejuran and Vitaran support skin repair and are particularly useful for thin, delicate skin. Purasomes exosomes, derived from bovine colostrum, deliver exosomes and growth factors that support skin renewal, and are often combined with medical microneedling.

Dermal fillers use hyaluronic acid to add volume directly where they are placed. Results are immediate and fillers can be dissolved if needed. They are the right choice for lips, tear troughs and precise contouring.Skin boosters focus mainly on hydration and glow, improving how skin looks and feels.Biostimulators focus on encouraging your own collagen, with results that build gradually. They suit people who have noticed thinning skin, laxity or loss of structure and want a natural-looking improvement.Many patients benefit from a combination. For example, a biostimulator to support overall structure, with filler for lips or a skin booster for hydration. Compare our skin boosters or dermal fillers.

BIOSTIMULATOR RESULTS - WHAT TO EXPECT
First few days:
Any swelling, redness or bruising settles. Radiesse gives visible structure straight away.
2 to 4 weeks:
Profhilo, Juvelook and Sunekos begin to show improved hydration and skin quality.
6 to 12 weeks:
Collagen production becomes more noticeable, with firmer, smoother skin.
3 to 6 months:
Sculptra and other collagen stimulators reach their fuller effect as new collagen matures.
Longer term:
Results vary by treatment and person, and maintenance sessions help sustain them.
Biostimulators reward patience. Because results build gradually, people tend to notice that you look refreshed rather than that you have had treatment.
WHO ARE BIOSTIMULATORS SUITABLE FOR?
Biostimulators may suit you if you have noticed thinning or crepey skin, loss of firmness, hollowing or softening of your facial contours, and you would like a gradual, natural-looking improvement.
They may not be suitable if you are pregnant or breastfeeding, have an active skin infection or inflammation in the treatment area, have certain autoimmune conditions, are prone to keloid scarring, or are looking for an instant, dramatic change.
A full medical consultation is carried out before every treatment, and we will always tell you honestly if a treatment is not right for you.
BIOSTIMULATOR FAQs
Where can I get biostimulator treatments in Cardiff?
Sebastian-Rose Medical Aesthetics offers Sculptra, Radiesse, Juvelook, Julaine, Profhilo Structura, Sunekos, polynucleotides, NCTF 135 and exosomes at 39 Charles Street, Cardiff city centre, CF10 2GB, for patients across Cardiff and South Wales. Injectable treatments are performed by GMC or NMC-registered medical professionals.
How much do biostimulators cost in Cardiff?
Biostimulator treatments at Sebastian-Rose start from £199 for polynucleotides and NCTF 135, from £240 for Profhilo, from £300 for Juvelook, from £320 for Sculptra, from £399 for Radiesse and from £750 for Julaine. Your exact price depends on the areas treated and the number of sessions, and Klarna payment options are available.
What is the difference between biostimulators and dermal fillers?
Hyaluronic acid dermal fillers add volume directly where they are placed. Biostimulators work mainly by encouraging your skin to produce its own collagen, so results develop gradually over weeks and months. Some, such as Radiesse, also give immediate structure.
How long do biostimulator results last?
It depends on the treatment. Skin-quality treatments such as polynucleotides and Profhilo usually need maintenance every 6 to 12 months, while collagen stimulators such as Sculptra and Radiesse are commonly reported to last longer. Results vary from person to person.
How many sessions will I need?
Most biostimulators are given as a course. Sculptra is usually 2 to 3 sessions, Profhilo 2 sessions, Sunekos 3 sessions and polynucleotides 2 to 3 sessions, while Radiesse often needs 1 to 2. Your plan is confirmed at consultation.
Which biostimulator is best for under-eyes?
Polynucleotides, Sunekos and Juvelook are commonly used under the eyes because they improve thin, crepey skin without adding bulk. Sculptra and Radiesse are not used in the tear trough.
Are biostimulators painful and is there downtime?
Numbing cream is applied beforehand, and many products contain or can be mixed with local anaesthetic. Most people return to normal activities straight away, with swelling, redness or bruising usually settling within a few days.
Can I combine biostimulators with other treatments?
Yes. Biostimulators are often combined with anti-wrinkle injections, dermal fillers, skin boosters or medical microneedling. Your practitioner will advise on the right combination and timing.
