Lorde + Belle RegenPen Weekly Cartridges

Lorde + Belle RegenPen Cartridges. Designed by Science. Includes 4 pieces. 4 Silicone nano tips designed for a more intensive weekly RegenPen treatment. Cartridges should be replaced after each use. This is helpful for people who have long, busy days and can't commit to daily use of the RegenPen. With the weekly cartridge you're getting a .18 mm silicone tip. This means your products are absorbing into your skin deeper compared to the Sensitive (.04 mm) and Daily (.08 mm) cartridges.
