Laennec Human Placenta Extract 2ml

Laennec® is a human placenta hydrolysate injectable preparation developed by Japan Bio Products (JBP) and classified in many regions as a pharmaceutical-grade placental extract (ethical drug / prescription product depending on country). It is used in medical and regenerative aesthetic contexts for liver support and skin quality improvement. It is intended only for use by licensed healthcare professionals under regulated medical conditions. Laennec is formulated as a bioactive placental extract solution containing low-molecular-weight peptides, amino acids, and growth-factor–like substances derived from human placenta hydrolysate. Unlike dermal fillers, Laennec is a biostimulatory injectable, not a volumizing product.

Packaging

• 1 vial / ampoule = 2.0 mL
• Common clinical packs: 10 or 50 ampoules per box (varies by market)
• Sterile glass ampoule, single-use

Composition

Each 2.0 mL ampoule typically contains:

• Human placenta hydrolysate (≈112 mg)
• Pepsin (enzyme used in manufacturing process)
• Lactose (trace excipient)
• pH adjusters and stabilizers

The extract includes a mixture of:

• Peptides
• Amino acids
• Cytokine-like bioactive components
• Low molecular weight regenerative fractions

Safety Information

Must be used only under qualified medical supervision.

Possible side effects:

• Injection-site pain or redness
• Mild swelling or irritation
• Allergic reactions (rare)
• Temporary discomfort at injection area

Important considerations:

• Derived from human placenta → requires strict manufacturing safety controls
• Regulatory classification varies significantly by country
• Not a dermal filler and not intended for volume enhancement

Mechanism of Action

Laennec works through biological stimulation rather than structural filling, including:

• Supporting cellular metabolism and tissue repair
• Promoting hepatocyte (liver cell) function in medical indications
• Enhancing skin regeneration and dermal vitality
• Improving microcirculation and tissue oxygenation indirectly
• Supporting antioxidant and anti-inflammatory pathways (reported effects in literature and clinical use)

It is considered a regenerative therapy rather than a cosmetic filler.

Product Features

• Human placenta hydrolysate-based injectable
• Low molecular weight bioactive compounds
• Regenerative (non-volumizing) action
• Sterile ampoule format (2.0 mL)
• Used in both medical and aesthetic protocols depending on jurisdiction

Expected Effects (Aesthetic Use Context)

When used in skin-quality protocols (where permitted), reported outcomes may include:

• Improved skin glow and radiance
• Better elasticity and firmness
• Reduction in dull or tired appearance
• Gradual improvement in skin texture
• Support for recovery after aesthetic procedures

Effects are typically progressive and cumulative, not immediate.

Common Uses

In regulated clinical or aesthetic contexts, it may be used for:

• Liver support therapy (medical indication in some regions)
• Skin rejuvenation protocols (off-label aesthetic use in some countries)
• Mesotherapy-style biorevitalization programs
• Support for fatigue and general vitality (reported use)
• Adjunct in anti-aging treatment plans
