Improper EDTA use during cosmetic procedure led to young woman’s death
A fatal aesthetic treatment has resurfaced critical questions about medical responsibility, patient safety, and oversight in Singapore’s booming cosmetic industry, following a doctor’s conviction nearly six years after the incident.
Conviction Over Dangerous Aesthetic Procedure
A Singapore court has convicted doctor Chan Bingyi, 37, of committing a negligent act that caused the death of property agent Lau Li Ting, 31, following an aesthetic treatment in March 2019. The ruling was delivered by Senior District Judge Ong Hian Sun on Jan 9, with sentencing set for March.
The case centered on Chan’s intravenous administration of ethylenediaminetetraacetic acid, or EDTA, at Revival Medical & Aesthetics Centre along Bras Basah Road. Prosecutors said the substance was used despite no medical indication and was delivered at an unsafe concentration and speed.
What EDTA Is and Why It Is Dangerous
EDTA is typically reserved for specific medical conditions such as heavy metal poisoning or elevated calcium levels, and must only be administered by clinicians trained in its use. Prosecutors stressed that disodium EDTA binds to calcium ions, which are essential for heart function, muscle movement, and nerve transmission.
Medical evidence showed that Ms Lau, who had no underlying health conditions, developed EDTA toxicity shortly after the procedure. She suffered a seizure, went into cardiac arrest, and was rushed to Singapore General Hospital, where she died on March 13, 2019.
Events Inside the Clinic
Court documents revealed that Ms Lau initially sought treatment for fine lines and skin concerns. Chan recommended cosmetic options such as a skin booster and laser treatment. However, he later agreed to perform a chelation procedure after Ms Lau insisted, citing past positive experiences elsewhere.
Chan admitted to the Ministry of Health that he prepared and administered EDTA and sodium bicarbonate through a saline drip. About five minutes into the infusion, Ms Lau became unresponsive and showed signs of seizure. Despite emergency efforts, she was found without a pulse when Singapore Civil Defence Force officers arrived.
Disputed Defense Claims Rejected
During the trial, Chan attempted to retract his earlier admissions, claiming the chelation treatment had not begun when Ms Lau collapsed. Prosecutors rejected this, describing the claim as implausible given his education and the consistency of medical evidence.
A defense expert suggested that unidentified pill residue found during autopsy could have contributed to her collapse. Prosecutors dismissed this theory, stating there was no evidence Ms Lau had consumed slimming products or other harmful substances prior to the incident.
Ongoing Regulatory Concerns
Despite the conviction, the Singapore Medical Council’s database shows Chan remains registered as a medical practitioner. He also faces three additional pending charges under the Health Products Act, including possessing expired injection ampoules at the same clinic in 2019. These charges will be addressed at a later date.
Broader Implications for Patient Safety
The case highlights the risks associated with off-label and non-essential aesthetic procedures, especially when dangerous substances are involved. It underscores the importance of strict adherence to clinical guidelines, informed consent, and regulatory enforcement within the cosmetic medicine sector.
This conviction sends a strong signal about accountability in medical practice, particularly in elective aesthetic treatments that blur the line between healthcare and consumer services. For Indonesians and Singaporeans alike, the case reinforces the need for caution, transparency, and stronger oversight as cross-border medical and aesthetic tourism continues to grow.
