Both experts agree on the key limitations: Facial exercises cannot change bone structure, significantly reduce fat, or shrink enlarged muscles in a lasting way.
“These techniques cannot alter your natural bone structure, such as a square jawline or flat cheekbones,” said Ho. “If someone has a naturally broader facial skeleton or fuller fat compartments, these approaches are unlikely to make a significant long-term difference,” Dr Yong added.
There are also risks if done incorrectly. “Repetitive facial movements may accentuate expression lines over time,” Dr Yong noted, particularly if exercises are performed too aggressively or without proper technique. Ho echoes this: “Facial muscles are often difficult to isolate. It’s vital to understand the ‘why’ behind a movement rather than blindly following a video.”
SO ARE THEY STILL WORTH IT?
That depends on what you’re hoping to achieve.
For quick, visible changes, gua sha can offer a temporary boost by reducing puffiness and enhancing definition. Face yoga, on the other hand, works more gradually, with consistent practice helping to improve muscle tone and facial habits over time.
But for significant contouring – especially when driven by bone structure or fat – medical treatments remain more effective. “Manual techniques can play a supportive role,” said Dr Yong, “but medical treatments are generally more effective when the goal is true facial contouring.”
Ultimately, facial exercises can change how your face looks – just not necessarily in the way most people expect. Rather than shrinking the face, they tend to refine it: Easing tension, reducing puffiness, and gradually improving muscle tone. The “slimmer face” effect is less about losing volume, and more about removing what doesn’t need to be there.
As with any form of self-care, results come down to consistency – and realistic expectations.
