About
Illuminator is a 50 g peel-off cream pack built around cysteamine, a pigment-regulating active positioned by the manufacturer as an alternative to hydroquinone. Applied in a thin layer, it forms a clear occlusive film in twenty to thirty minutes that is peeled away, leaving the essence on the skin. In the clinic it is the third step of the GD Tone-Up protocol; at home it continues the work between sessions. Formerly sold as GD Tone-Up Home Care.

Detailed information
Technology, indications and specifications as documented by Simfle Stick Co., Ltd.

- Cysteamine
- According to the manufacturer, cysteamine inhibits tyrosinase activation and melanin synthesis and shifts pigment production toward the lighter pheomelanin. It is presented as a hydroquinone alternative.
- The peel-off film
- The occlusive film stops the essence from evaporating while it works, then lifts away cleanly. There is nothing to wash off.
- With GD Tone-Up
- In the clinic Illuminator follows the laser pass; at home it maintains the result and, according to the manufacturer, helps guard against pigment returning between sessions.
