31 New Optical Illusions Created Entirely By Hand On This Korean Artist’s Face

Yoon works with one of the most unforgiving canvases possible — her own face — and refuses the safety net of digital editing. Every illusion is built slowly, layer by layer, while looking into a mirror that reverses everything she does. It’s a process that demands precision but also tolerance for discomfort; hours of painting, adjusting, stepping back, starting again. What looks immediate on screen is anything but. There’s a quiet stubbornness behind it, the kind that comes from years of training where repetition mattered more than inspiration, and where learning to see correctly was the first rule before breaking it.

But what really holds people isn’t just the technique, it’s the way her work unsettles something familiar. Faces are supposed to be easy. We read them instantly, trust them without thinking. Yoon interferes with that instinct just enough to make it unreliable. An extra eye, a shifted gaze, a feature that doesn’t quite belong, nothing dramatic, but enough to slow you down. And in that pause, you start noticing how fragile perception actually is. Her work doesn’t create illusion out of nowhere — it reveals how much of it was already there.
