Placenta (Laennec) Injection in Gangnam, Seoul

Medically reviewed by Dr. Kim Yoo Suk, MD · Board-certified otolaryngologist · Former professor, Yonsei & Ajou University · Consultations in English

What is a placenta (Laennec) injection?

Laennec is a prescription preparation made from human placental tissue that has been hydrolyzed into small peptides, amino acids and other components. It is produced under pharmaceutical regulation and is approved in Korea as a medicine; its officially approved indication relates to improving liver function in chronic liver disease. In wellness clinics, it is also offered more broadly, which is why understanding its actual approval and evidence is important.

Evidence and expectations

Claims that placenta injections reverse aging, boost immunity, cure fatigue or improve skin are not established by strong clinical evidence. This page makes no such claims. If you have a liver condition, management should be guided by a doctor who treats liver disease, not by wellness injections alone.

Who might consider it?

Some adults ask about placenta injections as part of a personal wellness plan. Before considering it, it is worth evaluating the reasons behind any symptoms such as tiredness, which can relate to sleep quality, nutrition, or treatable ENT problems like sleep apnea and allergic rhinitis that disturb rest.

Important considerations

• As a product derived from human tissue, it is manufactured with screening and processing designed to reduce infection risk, but the theoretical risk cannot be reduced to zero.
• Some countries restrict blood donation from people who have received human placenta products; check the rules in your home country if you donate blood.
• It is not recommended during pregnancy or breastfeeding without specific advice.

How it is done at our Gangnam clinic

Dr. Kim Yoo Suk, who taught otolaryngology at Yonsei and Ajou before opening his Gangnam practice, is board certified in ENT. The clinic follows a principled, patient-first approach and does not recommend excessive or unnecessary injections or IVs.

1. Medical review: your health history, medications, allergies, liver conditions and blood donation plans are discussed.
2. Private single-room suite: treatment takes place in your own quiet room.
3. Infection control: single-use consumables and strict hygiene procedures.
4. Administration: given according to the product's approved method; your session length is explained beforehand.

Nutrition and wellness injections are non-covered (non-insured) items, with fees explained in advance. Parking for IV-therapy patients is covered.

After your session

You can usually continue your day as normal. Mild soreness or redness at the injection site may occur. Contact the clinic if you develop rash, fever or swelling.

Risks and limitations

Possible side effects include injection site pain, redness or bruising, and rarely allergic reactions such as rash or itching. Benefits for general wellness are not proven. Decide only after weighing these factors, and avoid frequent repeated injections without a clear medical reason.

Practical information for foreign patients

Because regulations on placenta products vary internationally, ask about any implications for blood donation or travel before treatment. Dr. Kim can explain these points in English. See the IV therapy clinic, Dr. Kim's profile and the international patient guide, or compare with the glutathione IV.
