Key points

  • Phytosphingosine is a sphingoid base, the same class of molecule that forms part of the structure of ceramides.
  • It is used in formulas to support the skin barrier and provide a conditioning effect.
  • The ingredient is often paired with ceramides and other barrier lipids in moisturizers and serums.
  • It is generally well tolerated and appears in products aimed at supporting skin comfort and barrier health.

Frequently asked

How is phytosphingosine related to ceramides?

Phytosphingosine is a sphingoid base that serves as a structural component of certain ceramides in the skin. This connection is why it is often used alongside ceramides in barrier-supportive formulas.

Is phytosphingosine good for the skin barrier?

It is used as a barrier-supporting and conditioning ingredient and is commonly included in products designed to support skin comfort. As always, individual results vary and patch testing is sensible.
