This powerful daily or overnight treatment is infused with skin-brightening licorice, rejuvenating squalene, and soothing arnica that work to reduce wrinkles, improve circulation, and firm skin. **How to use:** For a daily serum, apply one to two pumps to clean skin to prep for foundation; you can also layer over night oils. For a quick mask, combine with a cleanser using a 2:1 ratio and let sit for 10 minutes before rinsing.
