Biostimulator Treatment: Stimulating Collagen and Improving Skin Quality

Biostimulators are injectable aesthetic treatments designed to support the body's natural tissue response, with many products focusing on collagen stimulation and improvement of overall skin quality.

As we age, changes in collagen production, skin elasticity, hydration, and tissue structure can contribute to fine lines, skin laxity, reduced firmness, and changes in skin texture.

Modern aesthetic medicine therefore increasingly focuses not only on adding volume, but also on improving skin quality, elasticity, hydration, and tissue structure.

At Nicha Clinic, Biostimulator treatments are selected based on the individual's skin condition, anatomy, age-related changes, and treatment goals.

There is no single “best” Biostimulator for everyone. Different products use different active ingredients and work through different mechanisms.

What Is a Biostimulator?

A Biostimulator is a term commonly used for injectable products designed to stimulate or support biological processes within the treated tissue, particularly collagen production or tissue remodeling.

Unlike conventional dermal fillers, which primarily focus on adding volume and restoring specific facial contours, many Biostimulators are designed to improve skin quality and tissue characteristics over time.

Depending on the product, Biostimulators may contain ingredients such as:

Recombinant collagen
Atelocollagen
Polycaprolactone (PCL)
Poly-D,L-lactic acid (PDLLA)
Hyaluronic acid (HA)
Polynucleotides (PN)

Because these ingredients have different mechanisms, Biostimulators should not be treated as one identical category.

The most appropriate product should be selected according to the patient's specific concerns rather than simply choosing the most popular brand.

What Can Biostimulator Treatments Help With?

Depending on the product, Biostimulator treatments may be considered for improving:

Skin laxity
Reduced skin firmness
Fine lines
Dry or dehydrated skin
Uneven skin texture
Visible pores
Reduced skin density
Certain types of acne scars
Overall skin quality

The expected outcome depends on the active ingredient, injection technique, treatment area, treatment protocol, and individual response.

Biostimulator vs. Dermal Filler

This is one of the most common questions patients ask.

Dermal Filler

Traditional dermal fillers are generally designed to restore or add volume in specific areas, such as the cheeks, lips, chin, temples, or nasolabial folds.

Biostimulator

Many Biostimulators focus more on stimulating biological processes and improving tissue quality, including collagen production, elasticity, hydration, or remodeling.

Some products may have both regenerative and volumizing properties, so the distinction is not always absolute.

The key difference is the primary treatment objective.

Why Is Collagen Important for Skin?

Collagen is one of the major structural proteins responsible for skin strength and structural support.

As the skin ages, collagen production and tissue organization change. This can contribute to reduced firmness, elasticity, and skin density.

Biostimulator treatments aim to support biological processes within the skin and tissue to encourage a more gradual improvement in skin quality.

The goal is not necessarily to create an immediate dramatic change, but to support a more progressive improvement in the treated tissue.

Biostimulator Options at Nicha Clinic

Nicha Clinic offers several Biostimulator options, allowing physicians to select an approach based on the patient's individual skin concerns.

1. Karisma Rh Collagen®

Karisma Rh Collagen® contains a recombinant human collagen Type I α1 chain combined with high-molecular-weight hyaluronic acid and carboxymethyl cellulose (CMC).

According to the manufacturer, the recombinant collagen component supports Type I collagen production in fibroblasts, while HA contributes to hydration and CMC is part of the product formulation.

Karisma may be considered for patients seeking:

Improved skin firmness
Better skin quality
Collagen support
Improved hydration
A more natural-looking skin rejuvenation approach

Karisma is positioned as a bio-restorative injectable collagen product rather than a conventional volumizing filler.

2. CollaJu

CollaJu is a collagen-based tissue supplement classified by its manufacturer as a medical device.

The official product information describes CollaJu as a collagen tissue supplement and states that it uses a patented Aseptic Salt Precipitation Method during manufacturing.

CollaJu is designed around a collagen-rejuvenation concept and may be considered for patients who want to support:

Skin firmness
Skin elasticity
Skin texture
Hydration
Overall skin quality

As with all injectable products, the appropriate treatment indication and technique should be determined by a qualified physician.

3. Belluxi

Belluxi is described in Thai-market product information as a PCL (Polycaprolactone)-based collagen stimulator designed to support collagen production and skin quality.

PCL is a biodegradable material that has been used in medical applications.

Belluxi is positioned around improving:

Skin firmness
Elasticity
Skin texture
The appearance of pores
Fine lines
Overall skin quality

The exact concentration, indications, treatment areas, and approved uses should always be confirmed against the actual product labeling and regulatory documentation for the product being used at the clinic.

4. Profhilo® / Phofilo

The name “Phofilo” is sometimes used in online searches or aesthetic clinic communications to refer to Profhilo®.

For medical and SEO accuracy, the official brand name should be written as Profhilo®, while “Phofilo” can be included as a secondary search term.

Profhilo® is based on high- and low-molecular-weight hyaluronic acid. Product information describes a formulation containing 32 mg of H-HA and 32 mg of L-HA per 2 ml, produced using IBSA's NAHYCO® technology.

Profhilo focuses on bio-remodeling, with an emphasis on improving hydration, elasticity, firmness, and overall skin quality rather than creating conventional filler-like volume.

Profhilo may be considered for:

Dehydrated skin
Reduced skin elasticity
Early skin laxity
Uneven texture
Dull-looking skin
Overall skin-quality improvement

The Profhilo range also includes body-focused applications according to the relevant product indication.

5. Juvelook

Juvelook is a Biostimulator combining PDLLA (Poly-D,L-lactic Acid) with Hyaluronic Acid (HA).

Product information describes PDLLA as the collagen-stimulating component, while HA contributes hydration and an immediate skin-conditioning effect.

Juvelook is commonly positioned for skin-quality concerns such as:

Skin texture
Visible pores
Fine lines
Early skin laxity
Certain types of acne scars
Uneven skin appearance
Hydration and radiance

Product information also describes applications involving the face, neck, and selected periocular areas according to the treatment technique and product indications.

6. Rejuran®

Rejuran® is an injectable medical device based on purified Polynucleotides (PN).

According to product information, the active ingredient consists of purified polynucleotides derived from DNA fragments processed using the manufacturer's technology.

Rejuran is positioned around supporting skin regeneration and skin quality rather than conventional volume enhancement.

It may be considered for concerns such as:

Thin or fragile-looking skin
Uneven skin texture
Fine lines
Dull or tired-looking skin
Certain types of acne-scar concerns
Overall skin-quality improvement

The exact indication depends on the specific Rejuran product and the treatment area.

Comparing Biostimulator Options

Product	Main Ingredient / Technology	Primary Treatment Concept
Karisma Rh Collagen®	Recombinant Human Collagen Type I + HA + CMC	Collagen support + skin quality
CollaJu	Collagen-based tissue supplement	Collagen rejuvenation + tissue support
Belluxi	PCL	Collagen stimulation + skin firmness
Profhilo®	High + Low Molecular Weight HA	Bio-remodeling + hydration
Juvelook	PDLLA + HA	Collagen stimulation + skin texture
Rejuran®	Polynucleotides (PN)	Skin regeneration + skin quality

This comparison is intended as a general overview of mechanisms and treatment goals. It is not a ranking of which product is better, because each product has different indications, formulations, clinical evidence, and treatment protocols.

Which Biostimulator Is Right for You?

There is no single answer based on age alone.

A physician should consider factors including:

If hydration and skin quality are the primary concerns
A hyaluronic-acid-based approach such as Profhilo® may be considered.

If collagen stimulation is the main goal
Products such as Karisma, Belluxi, or Juvelook may be considered depending on the patient's skin condition and treatment indication.

If skin regeneration and overall skin quality are the main concerns
A polynucleotide-based treatment such as Rejuran® may be considered.

If collagen and tissue support are the main concerns
Karisma or CollaJu may be considered depending on the individual assessment.

These are general principles rather than fixed rules. One patient may have several concerns at the same time, and the physician may recommend one product or a combination approach.

How Many Biostimulator Treatments Are Needed?

There is no universal treatment schedule.

The number of sessions depends on:

Product type
Active ingredient
Age
Skin condition
Degree of skin laxity
Treatment area
Treatment goals
Individual response

Each Biostimulator has its own treatment protocol. The recommended number of sessions for one product should not automatically be applied to another.

Are Biostimulator Results Immediate?

Results depend on the specific product.

Some products may provide early effects related to hydration or tissue conditioning, while collagen stimulation and tissue remodeling generally develop progressively over time.

Therefore, many Biostimulator treatments are not designed to create all of their effects immediately in the same way as conventional volumizing fillers.

Are Biostimulator Treatments Safe?

Biostimulator treatments are injectable medical procedures and therefore carry risks associated with both the injection procedure and the specific product.

Possible reactions may include:

Swelling
Redness
Bruising
Tenderness
Itching
Temporary lumps or injection-site firmness

More serious complications, such as infection, inflammatory reactions, or vascular complications, are uncommon but possible with injectable aesthetic procedures.

For this reason, treatment should be performed by a qualified physician with appropriate anatomical knowledge and injection expertise, using products that can be properly verified.

Why Should a Physician Select the Biostimulator?

Similar-looking aesthetic concerns may have completely different underlying causes.

For example, a less defined jawline may be related to:

Skin laxity
Localized fat
Volume loss
Reduced skin quality
Facial anatomy
Multiple age-related changes occurring together

Choosing a product based only on its brand name may therefore not address the primary concern.

A medical assessment allows the physician to select the appropriate product, treatment area, injection technique, and treatment plan.

Biostimulator Treatment at Nicha Clinic

At Nicha Clinic, Biostimulator treatments are based on a Personalized Skin Rejuvenation approach.

Rather than selecting a product simply because it is currently popular, the physician evaluates:

Skin Quality → Skin Laxity → Collagen Loss → Hydration → Facial Structure → Patient Goals

Based on this assessment, appropriate options may include:

Each product has a different formulation and treatment concept.

Conclusion

Biostimulator treatments are designed to support skin quality and tissue remodeling through biological processes rather than relying solely on immediate volume enhancement.

Karisma, CollaJu, Belluxi, Profhilo, Juvelook, and Rejuran use different active ingredients and treatment concepts. Therefore, there is no single Biostimulator that is universally “the best.”

The most important consideration is choosing the treatment according to the patient's skin condition, anatomy, treatment goals, and medical suitability.
