molecular designs by Jen Stark

@Jenstark 

"I'm endlessly inspired by the natural world - how enormous shapes out in the universe can have the same patterns as tiny microorganisms under a microscope. My work recreates those organic, molecular designs to showcase the infinite possibilities of expression, just like K18's biology-first haircare."
