Golden Diamant Plastic Surgery is a plastic surgery clinic on the 3rd floor of Cheongdam Square Building A, 420 Dosan-daero, Gangnam-gu, Seoul. Board-certified plastic surgeon Dr. Song Sang-hoon, the director, treats patients personally. The clinic centres on perioral surgery — mouth corners, philtrum and lips — alongside lifting and anti-ageing surgery, medical skin care and a private spa.

For philtrum reduction, the method is chosen to suit the face from more than seven approaches, including Golden Diamant (sub-nasal incision), lip-line, hybrid and Tetra. Signature treatments also include the Golden View mouth-corner lift, perioral revision surgery, MACS lift, double-chin muscle tightening with neck lift, lip filler, MCT stem-cell anti-ageing treatment and Regenera Activa, together with device-based skin treatments (Ulthera, Thermage, InMode, ONDA) and the Diamant Spa programme.

Dr. Song served as clinical instructor and clinical professor of plastic surgery at Korea University and as director of Golden View Plastic Surgery. He published a physician's guidebook on Belotero lip treatment and has worked as a training instructor for Allergan Juvéderm and Merz Belotero.

The clinic's view is that good surgery is "like a tailored suit rather than off-the-rack — beautiful without looking operated on", so it favours filling in what is lacking while keeping facial harmony, rather than following trends.
