What is Placenta?
Placenta is an extract derived from the placenta, containing numerous physiologically active substances such as amino acids, nucleic acids, growth factors, vitamins, and minerals. In Japan, two types are approved as pharmaceuticals: "Laennec (porcine-derived)" and "Melsmon (human-derived)."
| Product | Origin | Main Uses/Characteristics |
|---|---|---|
| Laennec | Porcine placenta | Widely used for improving liver function, beauty, and fatigue recovery. Commonly used in aesthetic clinics. |
| Melsmon | Human placenta | Covered by insurance for menopausal symptoms. Self-pay for aesthetic purposes. |
Main Effects of Placenta Injections
| Effect | Mechanism |
|---|---|
| Whitening/Spot Improvement | Auxiliary inhibition of melanin production by suppressing tyrosinase activity |
| Antioxidant/Dullness Improvement | Removes active oxygen and reduces oxidative damage. Improves skin tone. |
| Promotes Skin Metabolism/Normalizes Turnover | Growth factors and nucleic acids activate cell metabolism |
| Improves Firmness/Elasticity | Promotes collagen synthesis/activates fibroblasts |
| Fatigue Recovery/Increased Stamina | Improves liver function/promotes overall body metabolism |
| Alleviates Menopausal Symptoms | Auxiliary action on hormone balance (Melsmon may be covered by insurance) |
💡 The whitening and cosmetic effects of placenta injections are "supplementary." For strong effects on spots and melasma, a combination with oral tranexamic acid and topical hydroquinone is most effective. Our clinic can offer combination plans with online prescriptions.
How Many Sessions? Recommended Schedule
| Phase | Frequency | Estimated Duration |
|---|---|---|
| Initial Phase (achieve effects) | 1-2 times per week | 1-2 months |
| Maintenance Phase (sustain effects) | 1-2 times per month | Ongoing |
There is individual variation in when effects are felt; some people notice an "improved skin tone" or "less fatigue" after 3-5 sessions. For whitening and spot treatment, continued use for 2-3 months is recommended.
Side Effects and Precautions
- Pain/swelling at injection site: Rare. Mostly resolves in a few days.
- Allergic reactions: Extremely rare. Those with allergies should be cautious with porcine-derived Laennec.
- Inability to donate blood: Once you receive placenta injections, you will be unable to donate blood for life. Please confirm before treatment.
- Pregnancy/breastfeeding: Avoid use as safety has not been established.
Frequently Asked Questions
Yes, that's true. According to Japanese Red Cross regulations, if you have used pharmaceuticals containing human-derived components (such as Melsmon), you will be unable to donate blood for life. The same restriction applies to porcine-derived Laennec. Please confirm this before applying for treatment.
Yes, it can. Combining oral Tranexamic Acid (online prescription) to suppress melanin production internally with placenta injections to provide antioxidant effects and promote metabolism can lead to synergistic benefits. Please consult us about combination plans.
