Rejuran Collagen Stimulation
Drs. Tom van Eijk
Rejuran collagen stimulation refers to the gradual skin-repair response that may follow treatment with injectable polynucleotides. These substances are placed into the skin and may support processes involving fibroblasts, collagen, elastin and the extracellular matrix.
The treatment is intended to support skin quality rather than replace lost facial volume. Any visible changes usually develop progressively and may include smoother-looking texture, improved elasticity and greater skin resilience.
Results vary between people. Rejuran does not produce an immediate lifting or filling effect.
What is Rejuran collagen stimulation?
Rejuran collagen stimulation is the proposed process through which polynucleotides may support repair activity within the dermis. The dermis is the deeper skin layer containing fibroblasts, collagen fibres, elastin and the extracellular matrix.
Fibroblasts help maintain the structural components that influence how firm, elastic and resilient the skin feels. Rejuran is used with the aim of supporting this environment rather than physically adding volume.
Does Rejuran create new collagen immediately?
No. Collagen remodelling is a gradual biological process. Rejuran does not create instant firmness immediately after injection.
Temporary swelling can initially make the skin appear fuller, but this should not be confused with collagen formation or the final treatment result.
For a deeper explanation, read the Rejuran polynucleotides page.
How may Rejuran support collagen?
- 1 Rejuran is injected superficially into the skin
- 2 The skin responds to the injections
- 3 Polynucleotides may support the repair environment in the dermis
- 4 Fibroblast activity may be encouraged
- 5 Collagen and elastin remodelling may gradually improve skin texture
Fibroblasts, collagen and elastin: why they matter
Fibroblasts, collagen and elastin all play a role in skin structure. Rejuran is usually discussed when the aim is to support skin quality rather than create volume.
Component | Role in the skin | Why it matters |
|---|---|---|
Fibroblasts | Cells involved in collagen, elastin and skin repair | Important for skin structure and renewal |
Collagen | Provides support and firmness | Helps the skin look smoother and more resilient |
Elastin | Supports stretch and bounce | Helps the skin feel more elastic |
Extracellular matrix | Provides structure around skin cells | Supports dermal remodelling |
By supporting these processes, Rejuran may contribute to gradual improvement in skin texture, firmness and elasticity. Results vary between people.

When might you notice collagen stimulation after Rejuran?
The skin can look red, slightly swollen or bumpy just after treatment. This is part of the early recovery phase and does not show the final result.
Many people assess their skin after several weeks. Further changes may continue over the following months, depending on skin condition, age, treatment area, number of sessions, lifestyle and aftercare.
Period | What may happen | Note |
Week 1 | Early recovery after injections | Redness, swelling or small bumps may be visible |
Weeks 2–4 | Skin repair processes may increase | Changes are usually subtle |
Weeks 4–8 | Collagen remodelling may become more noticeable | Skin texture may look smoother |
Months 2–6 | Skin quality may continue to develop | Maintenance may be discussed during review |

Which skin concerns is Rejuran collagen stimulation relevant for?
Rejuran is most often discussed for concerns where skin quality, texture and elasticity are the main issue.
It may be considered for:
fine lines
reduced skin elasticity
thinner-looking skin
uneven texture
superficial acne scarring
early signs of skin ageing
dull or less resilient skin
For acne scarring, the type and depth of scarring matters. Read the Rejuran acne scars page.
Rejuran, Profhilo, skinboosters or fillers: what is the difference?
These treatments are often compared, but they are not the same. The main difference is the treatment focus: skin repair, hydration or volume.
Treatment | Main focus | Often considered for |
Rejuran | Skin repair and collagen remodelling | Skin quality, fine lines, elasticity and texture |
Profhilo | Hyaluronic acid hydration and skin quality | Dry, dull or lax-looking skin |
Skinboosters | Hydration and glow | Dehydrated skin and fine texture |
Fillers | Volume and contour | Cheeks, chin, jawline or deeper folds |
If someone is unsure between options, a consultation is important. The right treatment depends on skin thickness, skin quality, volume loss, expectations and medical background.

Realistic expectations and safety
Rejuran is not a quick volume treatment. The effect is usually gradual and more subtle than a filler. It is mainly used when the goal is to improve skin quality, texture and elasticity over time.
A suitable practitioner should assess your skin condition, skin thickness, treatment area, medical history, expectations and previous treatments before advising whether Rejuran is appropriate.
Temporary redness, swelling, tenderness, bruising, small bumps or visible injection points can occur. Read the Rejuran side effects and Rejuran recovery pages before booking.

When comparing Rejuran clinics, look beyond cost alone. A lower price is not always the safest or most suitable choice.
Check whether the clinic explains:
who performs the treatment
the practitioner’s relevant experience
whether a consultation is included
the expected number of sessions
possible side effects and downtime
aftercare instructions
review or follow-up options
total cost factors before treatment
No fixed UK price has been added here because costs can vary by clinic, practitioner, treatment area, product choice and number of sessions.

Frequently asked questions about Rejuran collagen
Does Rejuran really stimulate collagen?
Rejuran may support processes involved in fibroblast activity and collagen remodelling. This can contribute to gradual skin quality improvement, but results vary by person.
How does Rejuran collagen stimulation work?
Rejuran contains polynucleotides that are injected into the skin. They may support the repair environment in the dermis, where fibroblasts, collagen and elastin are active.
What are fibroblasts?
Fibroblasts are cells in the dermis involved in maintaining collagen, elastin and the extracellular matrix. They play an important role in skin structure.
When do results start after Rejuran?
Early redness or swelling may settle first. Skin quality changes are usually assessed after several weeks, with possible further development over the following months.
Is Rejuran the same as a skinbooster?
No. Skinboosters mainly focus on hydration and glow. Rejuran is more often discussed for skin repair, texture, elasticity and collagen remodelling.
Is Rejuran the same as a filler?
No. Fillers are mainly used to restore volume or shape facial contours. Rejuran focuses more on skin quality and gradual skin repair.
Can Rejuran help acne scars?
Rejuran may be considered for some superficial acne scars, but suitability depends on the scar type, depth and skin condition. A practitioner should assess this first.
Is Rejuran collagen stimulation suitable for everyone?
Not always. Suitability depends on your skin, medical history, treatment goals and expectations. A consultation is needed before deciding on treatment.
