Laennec: The Internal Regeneration Shot You Didn’t Know You Needed

Inspired by Nature, Perfected by Science

Let’s Talk About Placentas (Stay With Us)

Here’s a weird-but-true biological fact: most mammals eat their placenta after giving birth. This behavior—called placentophagy—isn’t just primal, it’s smart.

Why?

Because the placenta is a regenerative goldmine. It's packed with proteins, amino acids, hormones, and bioactive molecules that help the mother:

• Recover from labor

• Replenish lost nutrients

• Clean up the birthing space to avoid attracting predators

  
  

It’s such a natural part of mammalian behavior that humans, sea mammals, and camelids are the rare exceptions who don’t typically consume the placenta postpartum【1】.

That said, some cultures (notably in traditional Chinese and Vietnamese medicine) have practiced placental consumption, believing it could help with milk production or energy recovery after birth.

Now, don’t worry, we’re not suggesting you waltz into the labor and delivery department of your local hospital in search of a buffet-style placenta dinner.

What we are saying is that the science behind placental regeneration has sparked over a century of research into ways humans can safely benefit from its healing potential. And Laennec is one of the most refined, effective, and clinically validated results of that research.

Skin fibroblast activation from placental extract

From Primitive Instinct to Pharmaceutical Innovation

Scientific interest in placental therapies began in the early 1900s, when researchers discovered the placenta’s role in skin grafting and wound healing【2】.

By the 1930s–1980s, researchers began testing dehydrated, sterilized, and hydrolyzed forms of placental tissue, paving the way for pharmaceutical-grade extracts like Laennec, which uses both enzyme and acid hydrolysis to isolate the most bioactive fractions safely.

In modern regenerative medicine, the placenta is prized not just for its nutrient profile, but for its cellular building blocks, including:

• Trophoblast cells – essential for immune signaling and tissue repair

• Mesenchymal cells – stem-cell-like powerhouses that aid regeneration

• Endothelial cells – which support blood vessel formation and oxygen delivery

  
  

Even the umbilical cord gets attention. It contains Wharton’s Jelly, a cushiony gel packed with fibroblasts and hyaluronic acid, yes, the same compound in your favorite filler and glow serum【3】.

Laennec’s Modern Manufacturing Edge

Laennec ampoule with amino acids and growth factors

Unlike crude extracts or over-the-counter placenta serums, Laennec is:

• Clinically approved in Japan for injection

• Derived from ethically sourced human placentas + umbilical cords

• Manufactured using a dual hydrolysis process (enzyme + mild acid) to protect fragile proteins

• Undergoes multi-stage viral screening, heat sterilization, and pharmaceutical-grade ampouling

• Contains no preservatives or additives

  
  

In contrast, newer European processing techniques (e.g., Stellar Biomolecular’s EUF nano-filtrates) now use cold enzymatic digestion + ultra-filtration to preserve bioactivity under 10kDa for high absorption【4】a step that aligns with Laennec’s own molecular optimization.

The Cellular Mechanism of Action

So how does it actually work once injected?

Placental extracts like Laennec are rich in:

• PDRN (polydeoxyribonucleotide): DNA fragments that activate wound healing

• Peptides, amino acids, nucleic acids

• Growth factors (EGF, IGF-1, FGF, HGF, VEGF)

• Cytokines and interleukins

• Hormone precursors like DHEA-S and estradiol

  
  

According to this study in OAText Journals, once injected, these molecules:

1. Bind to specific cell surface receptors on damaged or inactive tissues

2. Trigger fibroblast activity, stimulating collagen, elastin, and extracellular matrix production

3. Modulate immune responses and decrease inflammation

4. Promote angiogenesis (new blood vessel formation) and tissue regeneration【5】

   
   

In skin terms? That means more glow, faster healing, and better resilience.

Laennec in Aesthetic and Functional Practice

You won’t find Laennec on a spa menu. This is a clinical injection, used in top regenerative clinics for:

• Skin Regeneration

  Post-procedure healing, dermal rejuvenation, and long-term anti-aging support

• Liver Detox & Hormonal Balance

  Supports estrogen clearance, hepatic repair, and DHEA-S restoration

• Chronic Fatigue & Burnout

  Improves nutrient status, mitochondrial signaling, and immune balance

• Immune Support & Inflammation Reduction

  Modulates cytokines like IL-1β, IL-6, TNF-α

 

What the Studies Say

• Liver repair: Laennec improves enzyme markers and inflammation in chronic hepatitis【6】

• Post-laser recovery: Enhances healing and reduces redness following ablative treatments【7】

• Cytokine modulation: Balances key inflammatory signals linked to autoimmune skin flares【8】

• Fatigue recovery: Supports adrenal function and energy levels in stressed individuals【9】
