A woman in Singapore endured 19 months of facial pain and professional setbacks after receiving an excessive dose of dermal fillers from aesthetic doctor Wong Kai Jie Isaac, according to a formal medical inquiry revealed on October 7. The patient disclosed enduring high blood pressure, shedding more than 20kg, grappling with mental health issues, and ultimately losing her job due to the complications.
Upon her initial consultation with Dr Wong at The Artisan Clinic on April 1, 2023, she consented to a treatment involving Ellansé dermal fillers. The product's packaging then stipulated a maximum annual dosage of 2ml, which the patient claimed she received in 7ml during a single session – more than three times the recommended amount.
Dr Wong contended that the manufacturer had set the 2ml limit to comply with Singapore's regulatory requirements in 2016, which was later increased to 12ml in March 2026, after the treatment and complaint.
Post the procedure, the patient encountered persistent pain on her left side of the face, leading Dr Wong to diagnose a blood vessel blockage and administer hyaluronidase injections. She continued attending follow-up appointments until October 2024, still experiencing persistent pain and nerve-related symptoms, while scans revealed severe narrowing or blockage in her facial arteries.
Dr Wong proceeded with additional treatments, including further injections of hyaluronidase and steroids. A colleague consulted during her treatment expressed doubt about the efficacy of more hyaluronidase injections.
Five further complaints were raised against Dr Wong during the inquiry, alleging excessive filler doses and adverse effects. Dr Wong's legal team argued that these complaints did not involve the same blood vessel complication and had not been found in their favor. The Interim Orders Committee (IOC) determined that there was a prima facie case and imposed interim restrictions on Dr Wong's medical practice to safeguard the public while the proceedings continued. However, the decision did not ascertain whether the allegations were ultimately substantiated.
Starting from August 26, Dr Wong was barred from administering or offering dermal fillers for up to 18 months, or until the relevant proceedings concluded, whichever occurred first. He was also prohibited from treating filler-related complications, except in a life-threatening emergency when he was the sole available physician. Additional conditions included him adhering to approved dosage and product specifications, disclosing his practice locations to the SMC, and informing employers of the restrictions.
The decision highlighted that while cosmetic procedures are elective, understanding the proposed treatment, its known risks, and available options before consenting is crucial. Doctors must also comply with applicable product guidance and ensure patients receive appropriate care when complications arise.
