Size: 1 device + 80ml conductive gel

The ZIIP device, the brainchild of LA-based electrical aesthetician Melanie Simon, has acquired legions of celebrity fans (Jennifer Aniston and Glossier founder Emily Weiss both rate it highly). It uses micro and nanocurrent waves to boost ATP levels (a cell's energy levels), which in turn stimulates collagen and elastin production - translating to a younger, healthier-looking complexion.

Simply sync your device with a smartphone app which provides a number of targeted programmes, like Instant Gratification (an intensive treatment delivering results in a condensed session) or Sculpt & Lift (described as a pilates class for your face). You might feel a little tingling or warmth - don’t worry, this is a good thing - but if it’s uncomfortable, it might be a sign you need to apply more of the conductive gel. We make a point of using it 2-3 times a week, as you certainly get the best results from regular and consistent use.
