Rejuran Collagen Stimulation

Q: Does Rejuran stimulate collagen?

Rejuran is used to support processes involved in fibroblast activity, skin repair and collagen production. The effect is gradual and varies per person.

Q: How does collagen stimulation with Rejuran work?

Rejuran uses polynucleotides, which are injected into the skin to support repair processes linked to fibroblasts, collagen and skin structure.

Q: What role do polynucleotides play in skin rejuvenation?

Polynucleotides are used to support skin repair and regenerative skin-quality processes. They are often discussed in relation to fibroblast activity and collagen support.

Q: When does collagen production start after Rejuran?

Skin repair processes may begin in the first weeks after treatment, but visible results usually develop gradually over time.

Q: How long does collagen stimulation continue after Rejuran?

The timeline varies per person. Skin-quality changes may continue to develop over several months depending on skin condition and treatment plan.

Q: Is Rejuran a skinbooster?

Rejuran is often grouped with skinboosters, but it works differently from traditional hyaluronic acid skinboosters because it focuses more on regenerative skin-quality support.

Q: What is the difference between Rejuran and Profhilo?

Rejuran contains polynucleotides and is often used for skin repair and texture. Profhilo contains hyaluronic acid and is mainly used for hydration and bio-remodelling.

Q: Can Rejuran help with acne scars?

Rejuran may be considered for some types of acne scarring because it supports skin-quality and texture improvement. Suitability should be assessed during consultation.

Q: Which skin layer does Rejuran target?

Rejuran is injected into the skin and is mainly discussed in relation to the dermis, where fibroblasts and collagen structures are found.

Rejuran collagen stimulation refers to the way Rejuran polynucleotides are used to support processes involved in skin repair, collagen production and improvement in skin texture.

Rejuran is often discussed as a regenerative injectable treatment because it focuses on skin quality rather than adding volume. The treatment is commonly considered for concerns such as fine lines, acne scarring, reduced elasticity and uneven skin texture.

Polynucleotides are used in aesthetic medicine to support fibroblast activity in the dermis. Fibroblasts are cells involved in producing collagen, elastin and other structural components of the skin. Over time, this may help the skin look gradually firmer, smoother and more resilient.

What is Rejuran collagen stimulation?

Rejuran collagen stimulation describes the skin-quality effect associated with Rejuran polynucleotides. The treatment is used in protocols that aim to support the skin’s natural repair processes and improve the appearance of texture, elasticity and firmness.

What are polynucleotides?

Polynucleotides are purified DNA fragments used in regenerative aesthetic treatments. PDRN is a related term often used in this area, although terminology can vary depending on the product and treatment protocol.

In Rejuran treatments, polynucleotides are used to support skin repair and fibroblast activity.

Why is collagen important for the skin?

Collagen helps give the skin structure and firmness. Collagen type I is important for strength, while collagen type III is involved in elasticity and early tissue repair.

As collagen quality and quantity change with age, the skin may start to look thinner, less firm or less even in texture.

How may Rejuran support collagen production?

Rejuran is injected into the skin using small intradermal injections. The polynucleotides are used to support processes involved in skin repair, fibroblast activity and collagen formation.

The role of fibroblasts

Fibroblasts are cells in the dermis that help produce collagen, elastin and components of the extracellular matrix, also known as the ECM.

The ECM provides structural support within the skin. When skin repair processes are supported, the skin may gradually appear smoother, firmer and more even.

From polynucleotides to skin remodelling

The process is gradual rather than immediate:

Polynucleotides are injected into the skin.
Skin repair processes are supported.
Fibroblast activity may increase.
New collagen and elastin support may develop over time.
The skin texture and firmness may gradually improve.

Visible changes are not instant and results vary per person.

Which types of collagen matter for skin quality?

Different types of collagen contribute to the structure and appearance of the skin.

Collagen type	Role in the skin
Collagen type I	Supports firmness, strength and skin structure
Collagen type III	Supports elasticity and early tissue repair

Rejuran is not a filler and does not add facial volume. It is mainly used as a skin-quality treatment.

What happens in the skin after a Rejuran treatment?

Changes after Rejuran usually develop gradually. The exact timeline depends on the treatment area, skin condition, product used and the number of sessions recommended by the clinic.

Period	What may happen
Immediately after treatment	Temporary redness, swelling or small injection bumps may appear
First few weeks	Skin repair processes and fibroblast activity may be supported
Weeks 4–8	Collagen support and texture changes may become more noticeable
Following months	Skin firmness, elasticity and texture may continue to improve gradually

Some people notice subtle changes earlier, while others need more time or a course of treatments. Suitability and expected results should be discussed during consultation.

Which skin concerns is collagen stimulation used for?

Rejuran may be considered when the aim is to improve skin quality rather than add volume.

Common concerns include:

Fine lines
Acne scarring
Reduced skin elasticity
Uneven skin texture
Dull-looking skin
Early visible signs of ageing

The treatment may not be suitable for everyone. A consultation is needed to assess your skin, medical history and expectations.

Rejuran or other skin-quality treatments

Rejuran is one of several injectable treatments used for skin quality. It is often compared with Profhilo, traditional skinboosters and fillers, but each treatment has a different purpose.

Treatment	Main mechanism	Main aim
Rejuran	Polynucleotides	Skin repair and regenerative skin-quality support
Profhilo	Hyaluronic acid	Hydration and bio-remodelling
Skinboosters	Hyaluronic acid	Hydration and skin quality
Fillers	Volume replacement	Contour or volume restoration

Rejuran is usually not chosen for volume replacement. If volume loss is the main concern, a practitioner may discuss other options such as dermal fillers.
