Local woman Cheryl Tan has achieved the ultimate Singaporean dream: a face as immobile as the traffic on the Causeway.

After a RM150 "Premium Mystery Fluid" injection in a JB back-alley clinic located behind a tyre shop, the 26-year-old’s forehead is now legally classified as a bulletproof surface.

Medical experts suggest the substance used was likely a cocktail of industrial-grade sealant and leftover durian husk essence.

"Eh, the doctor say is organic one leh, don’t play play," Cheryl said, speaking through a three-millimetre gap in her frozen lips.

"Last time my face move too much, very tiring one, now I save money on skincare and also cannot show emotion when my boss scold me, damn worth it."

Customs officers at Woodlands Checkpoint reportedly spent forty minutes trying to verify her identity after facial recognition software mistook her for a highly polished marble statue.

"Liddat is best lor, my mother-in-law scold me also I just stare at her like one dead fish, she thought I transcending already," she added while blinking one eye at a time.

Cheryl plans to return next week for a budget lip filler administered via a high-pressure bicycle pump.
