What it is
Vitis Coignetiae Sap is the clear fluid collected from the stems of the Crimson Glory Vine, a plant native to East Asia. It contains water, natural sugars, minerals, and antioxidant compounds like polyphenols.
How it works
When applied to the skin, the sap acts as a humectant, drawing moisture from the air into the outer layer of your skin. Its antioxidant content helps neutralize free radicals caused by UV and pollution, while its natural sugars may form a light film that soothes and protects.
Pros
Gentle hydration
Provides a light, non-sticky layer of moisture that feels comfortable on all skin types, especially sensitive skin.
Antioxidant support
Contains natural polyphenols that help protect skin from daily environmental damage like pollution and UV rays.
Cons and cautions
Limited research
Most evidence comes from traditional use and lab studies, not large human trials, so its effectiveness is less proven than common alternatives.
Lower potency
As a natural sap, its humectant power is generally weaker than concentrated ingredients like hyaluronic acid or glycerin.
Best for
- People with dry or dehydrated skin looking for a gentle hydrator
- Those with sensitive or easily irritated skin who want a soothing ingredient
Use caution if
- Individuals with a known allergy to grapes or grapevines
Usage tips
Safety summary
