What it is
A sap extract obtained from the trunk of the manna ash tree (Fraxinus ornus), traditionally used for its mild laxative and soothing properties, now explored in cosmetics for its potential anti-inflammatory and humectant effects.
How it works
The extract contains compounds like mannitol and other sugars that can attract and hold moisture to the skin's surface, acting as a humectant. It may also help reduce visible redness and irritation by calming inflammatory pathways, though the exact mechanism is not fully understood.
Pros
Gentle soothing potential
Early research suggests it may help calm redness and irritation, making it a good option for sensitive skin routines.
Lightweight hydration
Acts as a humectant, drawing moisture to the skin without leaving a sticky or heavy feel, suitable for oily or combination skin.
Cons and cautions
Limited evidence
Most benefits are based on traditional use and preliminary studies; robust clinical trials on skin are scarce.
Rare allergen risk
While generally safe, individuals with tree sap allergies could experience a reaction, so patch testing is wise.
