Close-up of blue beads in petri dishes with text labels.

A woman holds up two petri dishes filled with blue beads, one labeled 'Thiamidol' and the other 'Vitamina C'. She then holds up two dropper bottles, presumably containing serums. She transfers beads into test tubes and adds serum from each bottle, letting them sit for 24 hours. Finally, she shows the results, with the 'Thiamidol' beads appearing larger and more luminous, and then touches her glowing face.
