First, obviously, you need a face roller, which you can find here (along with all our other skincare tools). You can choose your stone based on your personal colour preference and what will match your bathroom (no judgement here, we often do the same), or on the particular properties associated with each crystal: jade (calming), rose quartz (emotionally healing), amethyst (anti-inflammatory), or black obsidian (balancing).
And that's it, really. The beauty of a face roller is that it can be done anywhere, anytime, whether that's on clean and dry skin, straight after your skincare session, or over a full face of makeup, first thing in the morning, last thing at night, or right before you head out on date night.
The only must-do is to make sure you clean your face roller after each and every single use (especially if you like to roll over your makeup).
