What it does
- Supports the skin barrier as a ceramide precursor.
- Soothes and helps calm blemish-prone, reactive skin.
- Provides mild antimicrobial character.
How it works
Phytosphingosine is a sphingoid base — part of the ceramide family and a building block of barrier lipids. It is widely documented for barrier-support, soothing and mild antimicrobial activity, and is effective at very low levels.
Use level
- Typical use level
- typically 0.1–0.5%
Used at low levels, commonly 0.1–0.5%. Often paired with ceramides and cholesterol.
Formulation considerations
- Oil-soluble; requires heat and emulsification.
- Effective at low levels.
- Pairs with ceramides, cholesterol and fatty acids.
What it pairs with & what to avoid
Pairs well with
- Ceramides and cholesterol (barrier blend)
- Niacinamide
Use with care / avoid
- Poorly emulsified systems (uneven delivery)
Regulatory status
Phytosphingosine is listed in the EU CosIng database and is a well-established barrier-support ingredient.
