Can I use Squalene with Tocopherol?
Works well together
Squalene and Tocopherol are generally compatible and can be layered in the same routine. As always, introduce one new active at a time and watch how your skin responds.
SqualeneEmollient
- ✓Natural component of human sebum (~10–15%) — highly skin-compatible
- ✓Emollient that softens and smooths skin
- ✓Supports the skin's surface lipid film
- ⚠Prone to oxidation on exposure to air and UV, forming squalene peroxides — comedogenic and pro-inflammatory byproducts
- ⚠Oxidised form (squalene monohydroperoxide) is more comedogenic than established comedogenic cosmetic ingredients in controlled studies
- ⚠May contribute to acne vulgaris when oxidised on skin surface
