Aesthetic doctor Yap Wei Qiang is under investigation following reports of long-term side effects from excessive dermal filler injections. The patient, identified only as a woman, claims the treatment caused significant health complications.

The incident occurred in Singapore, where Yap, a licensed aesthetic physician, administered an unusually high volume of dermal fillers during a cosmetic procedure. According to medical reports, the patient experienced persistent swelling, skin discoloration, and mobility issues in the treated area.

This case follows a rise in cosmetic procedures involving dermal fillers, with increasing concerns over improper use. Regulatory bodies in Singapore have begun reviewing cases of over-treatment, emphasizing the need for stricter guidelines. The patient is currently undergoing medical evaluation, and legal proceedings are expected to begin soon.
