How to use squalene
Wanna give it a try? Your best bet is to apply by following squalene product instructions.
Here are some tips for layering this skin-soother into your routine:

- Remember that a little goes a long way. Squalene doesn’t feel oily, but it’s still oil. Start with a drop or two, then add more as needed.
- Don’t forget the sunscreen. You can — and should — apply SPF after squalene. Just allow the squalene product to dry down before misting/slathering/brushing on a quality mineral sunscreen.
