COLLAREJU is a high-purity Type 1 collagen supplement derived from porcine sources, designed for direct insertion into areas with collagen deficiency. It employs a unique cold-processing method to preserve the collagen’s natural structure and minimize immune reactions, thereby offering effective tissue repair and rejuvenation. 

• Fast Collagen Absorption: Promotes rapid tissue repair and rejuvenation.
• Cold-Processed: Maintains collagen’s natural structure for maximum effectiveness.
• Reduced Immune Risk: Uses Type 1 atelocollagen to minimize immune reactions.

CollareJu is a collagen-based tissue supplement designed for direct injection into areas with collagen deficiency. It is classified as a Class 4 medical device and approved by the Ministry of Food and Drug Safety (MFDS) of Korea.

Main Benefits

• Targets Collagen Loss Directly
  CollareJu is injected straight into areas with collagen deficiency, helping to visibly improve skin structure and support tissue repair where it's needed most.
• Preserves Collagen's Natural Power
  Made using a cold-processing method (below 7°C), it preserves the collagen's natural structure for improved absorption and effectiveness.
• Minimizes Risk of Immune Reactions
  Uses purified Type 1 atelocollagen, which is specially treated to reduce the chance of triggering unwanted immune responses.
• Clean and Safe Formula
  Carefully filtered and virus-inactivated, CollareJu delivers high-purity collagen free from impurities, ensuring safe and reliable results.

Indications

CollareJu is designed for direct collagen supplementation through injection, addressing areas affected by collagen loss and tissue degradation. It supports tissue repair, skin rejuvenation, and collagen replenishment in regions where natural collagen has diminished due to aging or other factors.

• Fine Lines and Wrinkles
• Skin Laxity
• Volume Loss:
• Collagen-Depleted Areas

Common treatment areas include the face (such as cheeks, nasolabial folds, and jawline), neck, décolletage, and hands, where improved elasticity, firmness, and skin texture are often desired. CollareJu contains Type 1 atelocollagen, known for its structural role in the skin and reduced risk of immune reactions, making it suitable for both aesthetic and regenerative applications.

Mechanism of Action

CollareJu provides Type 1 atelocollagen directly into areas with collagen deficiency. By injecting the collagen where it is needed, it helps improve skin structure and supports natural tissue repair.

Stimulates Natural Regeneration

Once injected, the collagen acts as a scaffold that encourages the body’s cells to regenerate tissue, enhance skin elasticity, and improve firmness and texture over time.

Biocompatible and Safe

CollareJu utilizes atelocollagen, a purified form of Type 1 collagen with a reduced risk of immune response. This is achieved by removing antigenic telopeptide regions, making it safer and more compatible with the body’s natural tissues.

Preserved Collagen Structure for Effectiveness

Thanks to a unique cold-processing technique (maintained at a temperature below 7°C during production), CollareJu preserves the collagen’s natural triple-helix structure. This enhances its biological activity, allowing it to work more effectively in tissue repair and skin rejuvenation.

Product Preparation

CollareJu is supplied as a ready-to-use, purified collagen solution for direct injection. No reconstitution or dilution is required. The product should be prepared and handled by qualified professionals in accordance with standard sterile procedures.

Preparation Guidelines:

• Ensure the product is stored and handled under recommended conditions (below 7°C) to maintain collagen stability.
• Allow the product to reach a suitable working temperature before injection, as advised by the manufacturer or local clinical protocol.
• Use sterile syringes and needles appropriate for collagen injection procedures.
• Inspect the product visually before use. Do not use if there are signs of contamination or abnormal appearance.

⚠ Note: CollareJu is classified as a Class 4 medical device and must be administered by licensed medical professionals following official guidelines.

 

Treatment areas

CollareJu is intended for direct collagen supplementation in areas where collagen loss and tissue weakening have occurred. It is suitable for both facial and body applications, depending on professional assessment.

Face:

• • Cheeks
  • Nasolabial folds
  • Temples
  • Jawline
  • Perioral area (around the mouth)
  • Chin

Body:

• • Neck and décolletage
  • Hands
  • Arms (mild skin laxity)
  • Abdomen (selected areas)
  • Other localized areas with visible collagen deficiency

CollareJu is typically used to improve skin texture, elasticity, and volume in areas affected by aging, environmental damage, or other factors that lead to collagen loss.

Dosage and technique

CollareJu is a Class 4 medical device intended for injection by licensed healthcare professionals trained in collagen-based procedures.

• The appropriate dosage and injection technique should be determined by the treating professional, based on the patient’s individual needs and the area being treated.

• CollareJu is designed for intradermal or subcutaneous injection into areas showing signs of collagen deficiency.

• The product does not require reconstitution and is supplied ready for direct injection.

• Professionals should follow standard sterile injection protocols and adhere to local regulations and best practices.

• Dosage may vary depending on the treatment area, skin condition, and desired outcomes.

Post-treatment

Proper post-treatment care helps optimize the results of CollareJu collagen injections and minimize the risk of side effects. Patients should follow professional guidance after the procedure.

 General recommendations include:

• Avoid touching or massaging the treated area for at least 24 hours unless advised by the practitioner.

• Minimize Sun Exposure: Avoid direct sunlight, tanning beds, and heat exposure (saunas, hot baths) for several days after treatment.

• Stay Hydrated: Drinking plenty of water may support the skin’s natural collagen remodeling process.

• Avoid Makeup: Refrain from applying makeup on the treated area for at least 24 hours.

• Limit Physical Activity: Avoid strenuous exercise or activities that may cause sweating for 24–48 hours.

• Cold Compress (if needed): In case of minor swelling or redness, apply a cold compress gently to the area.

• Follow Professional Instructions: Always follow the specific aftercare instructions provided by your treating healthcare provider.

⚠ Note: Mild swelling, redness, or tenderness may occur temporarily after the injection and typically resolves within a few days. Contact a qualified professional if any unexpected or prolonged symptoms occur.

Course of Treatment

Sessions
Typically, 2–3 sessions are recommended to achieve optimal results.

Weeks
Sessions are commonly spaced 4 to 6 weeks apart to allow for proper collagen remodeling and tissue regeneration.

Months
To sustain the results, maintenance sessions may be performed every 6 to 12 months, depending on the individual's skin condition, aging process, and treatment goals.

How quickly will the result appear?

Weeks

Some visible improvement may be noticed as swelling subsides within the first few days after treatment. The treated area may appear smoother and slightly firmer due to the immediate collagen presence.
