RAINBOW PCLA SCREW 29G38-50mm

RAINBOW PCLA SCREW 29G38-50mm is a biodegradable screw-type thread made from PCLA (Poly L-Lactide-co-ε-Caprolactone), designed for non-surgical skin lifting, tightening, and volumization. This product features a 29-gauge needle with a 38 mm thread length and 50 mm total needle length, allowing for precise treatment of fine lines, periorbital wrinkles, and early skin laxity. The screw configuration enhances dermal stimulation by creating controlled micro-injuries, which trigger collagen and elastin production, resulting in firmer, more youthful skin. PCLA offers longer biodegradation and sustained neocollagenesis compared to PDO, making this thread ideal for patients seeking natural but longer-lasting rejuvenation.

• Thread type: Screw (coiled for increased stimulation)
• Material: PCLA
• Use case: Volumization and tightening of fine lines and shallow folds
• Longevity: Up to 18–24 months

This product is administered intradermally using a 29G needle, with the screw thread delivering enhanced collagen stimulation due to its spiraled structure. It is ideal for superficial facial zones.

• Needle size: 29G
• Thread length: 38 mm, needle length 50 mm
• Thread type: Screw (twisted mono)
• Injection depth: Superficial to mid dermis
• Technique: Linear, spiral, or fan placement
• Treatment zones: Glabella, crow’s feet, perioral wrinkles, under-eye areas
• Procedure duration: 15–30 minutes
• Downtime: Minimal

RAINBOW PCLA SCREW is indicated for patients with fine wrinkles, reduced skin tone, or early signs of aging, especially in areas where skin requires gentle lifting and firming. Its structure allows for greater volume effect compared to mono threads.

Indications:

• Crow’s feet, glabellar lines, perioral wrinkles
• Skin laxity in delicate areas (cheeks, jawline)
• Collagen loss and dull skin tone
• Post-acne skin revitalization

Contraindications:

• Pregnancy or lactation
• Severe skin infection or active inflammation
• Coagulation disorders
• Autoimmune diseases
• Known hypersensitivity to PCLA components

Side Effects:

• Redness, swelling, tenderness at injection sites
• Mild bruising or discomfort
• Rare: Thread migration, infection, or asymmetry

RAINBOW PCLA SCREW threads are made from PCLA (Poly L-Lactide-co-ε-Caprolactone), offering strong elasticity, durability, and biocompatibility.

• Poly L-Lactide (PLLA) – initiates neocollagenesis
• ε-Caprolactone (PCL) – provides elasticity and soft degradation profile
• Structure: Screw-type for increased mechanical and biological stimulation
• Absorption time: Gradually absorbed over 18–24 months
• Byproducts: CO₂, H₂O, and glucose – safely excreted by the body

The threads are packaged in sterile, single-use units, intended for professional use in aesthetic or dermatological clinics.

• Quantity: 20 threads per box
• Packaging: Sterile individual pouches
• Needle specification: 29G x 50 mm, preloaded with 38 mm thread
• Certifications: CE-marked, ISO13485, KFDA, GMP-compliant
• Labeling: Treatment area, needle gauge, lot number, expiration date

RAINBOW PCLA SCREW is considered safe with proper technique. Adverse effects are typically mild and resolve within days.

Common Side Effects:

• Transient erythema, swelling, bruising
• Tenderness or itching
• Mild asymmetry

Rare Side Effects:

• Infection
• Thread exposure
• Nodules or granulomas
• Hyperpigmentation

To preserve sterility and product integrity, the threads must be stored under appropriate conditions.

• Storage temperature: 2°C to 25°C (36°F to 77°F)
• Avoid freezing
• Protect from humidity and direct sunlight
• Keep sealed until use
• Do not resterilize or reuse – single-use only
