What It Means for Mulgwang Injection to Be Patented — The Story Behind Patent No. 10-1790405 and an International Paper
Mulgwang injection (skin-hydration injection) has become a common treatment offered at many clinics. But to the question “Is mulgwang injection the same at every clinic?” we can answer with confidence: no. The technique used can make a real difference to the outcome.
What is mulgwang injection?
Mulgwang injection (also called a “water injection” or hydration injection) is a dermal hydration treatment that injects small amounts of stabilized hyaluronic acid (HA) into the dermis at closely spaced intervals to restore moisture deep within the skin. Kim Jongseo Plastic Surgery primarily uses Restylane Vital, a stabilized HA product, for its long-lasting effect, smooth spread, minimal clumping, and its ability to support collagen synthesis.
Korean Patent No. 10-1790405 — What Does It Recognize?
Dr. Kim Jongseo filed a patent application in 2015 for “A Mulgwang Injection Method Using Stabilized Hyaluronic Acid and a Syringe” and was granted the Korean patent on October 19, 2017 (patent holder and inventor: Kim Jongseo). A patent means that the government has officially recognized the novelty and originality of the injection technique. However, a patent is not a guarantee of treatment outcome, and results vary by individual.
Research Published in the International Journal JCD
A study that further developed this injection method was published in 2020 in the international journal Journal of Cosmetic Dermatology (doi:10.1111/jocd.13462). The study examined the effects of intradermal injection of a stabilized HA and botulinum toxin mixture (hydrotoxin) on acne scars, using computerized skin topography analysis and histological examination.
How Often Should It Be Done?
The manufacturer recommends 3 sessions spaced 4 weeks apart, but given the long-lasting characteristics of Vital hydration injections, Kim Jongseo Plastic Surgery generally recommends a session once every 6 months to a year. The appropriate interval may vary depending on your skin condition, so please discuss this during your consultation.
