Main Ingredients
Human Placenta Extract (112 mg per ampoule)
A bioactive extract rich in growth factors, peptides, amino acids, and cytokines that support skin rejuvenation, improved texture, post-procedure healing, and overall vitality.
Pepsin (Trace)
Used during processing to help release active components from the placenta.
Lactose (0.6 mg)
A minimal stabilizing ingredient included in the formula.
pH Adjuster (q.s.)
Balances the product to maintain ideal texture and stability.
Mechanism of Action
Laennec works through its water-soluble human placenta extract, which naturally contains a mix of growth factors, cytokines, amino acids, peptides, and other bioactive elements. Together, they help the body’s repair systems work more efficiently.
It encourages cellular renewal, helping skin create fresh, healthy cells and supporting smoother tissue repair. Certain growth factors like HGF also play a role in liver regeneration, helping activate the cells involved in restoring healthy liver function.
Laennec can also help calm inflammation, which contributes to better skin texture and more comfortable healing. Its regenerative components support faster recovery after procedures such as peels, laser treatments, or other skin-focused aesthetic work.
Because the extract contains many active substances that naturally complement each other, Laennec works in a synergistic way, promoting overall repair, recovery, and vitality from the inside out.
What Makes Laennec Different
Laennec is unique because it combines medical-grade purity with benefits that extend into cosmetic and skin-rejuvenation procedures. Using JBP’s advanced extraction technology, the placenta extract retains a rich concentration of growth factors, cytokines, and bioactive molecules that are highly valued in aesthetic treatments for improving skin quality, healing, and overall regeneration.
Its formulation supports faster recovery after cosmetic procedures such as lasers, deep peels, micro-needling, and plastic-surgery prep, making it a trusted option in aesthetic clinics that require reliable regenerative results.
Every batch undergoes strict NAT virus testing and high-pressure sterilization, meeting some of the most rigorous global safety requirements. This distinguishes Laennec from cosmetic-grade placenta products—its clinical background and high bioactivity make it especially effective for skin repair, brightening, and revitalization protocols used in modern aesthetic care.

- Neck & Décolletage: Laxity, dullness, aging-related changes

Product Benefits Energy and glowing skin
Age 42
I use laennec both IM and for microneedling and I cannot say enough good things about what it has done for my skin and energy. Skin is tighter and smoother over all, pores have shrunk. I use topically after plasma pen treatments and it seriously expedites the healing time. When I’m not feeling well, I use as IM injection and it gives such an incredible energy boost. I will never be without this product!
