Ingredient review
Burnet Xylem Sap
INCI: Sanguisorba Officinalis Xylem Sap
A gentle, plant-derived sap that may help calm irritated skin and provide antioxidant protection, though research is still early.
In plain English
This is the sap from the xylem (the water-conducting tissue) of the burnet plant, a herb used in traditional medicine. In skincare, it's valued for its potential to soothe redness and protect skin from environmental stress, similar to how aloe vera or centella asiatica work. It's a very gentle ingredient, unlikely to cause irritation, making it suitable for sensitive skin types.

What it is
A watery sap collected from the xylem of Sanguisorba officinalis (great burnet), a flowering plant in the rose family. The sap contains natural sugars, minerals, and antioxidant compounds like tannins and flavonoids.
How it works
The sap's antioxidant compounds help neutralize free radicals that can damage skin cells. Its soothing properties are thought to come from anti-inflammatory compounds that calm irritated skin and reduce redness. The sap also provides light hydration due to its water content and natural humectants.
Pros
Very gentle
Unlikely to cause irritation or clog pores, making it safe for sensitive and acne-prone skin.
Natural antioxidant
Provides a plant-based source of antioxidants that can help protect skin from daily environmental damage.
Cons and cautions
Limited research
Most evidence comes from traditional use and lab studies; there are few human clinical trials confirming its skincare benefits.
May be less effective
Compared to well-studied soothing ingredients like niacinamide or centella asiatica, burnet sap may have a milder effect.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, natural antioxidant ingredient
Use caution if
- Anyone with a known allergy to plants in the Rosaceae family (rare)
Usage tips
Safety summary
Burnet xylem sap is considered safe for topical cosmetic use with a very low risk of irritation or allergy. As with any new plant ingredient, patch testing is recommended for those with very sensitive skin or plant allergies.
Research notes
Research on burnet sap in skincare is emerging. Lab studies show antioxidant and anti-inflammatory activity, but human clinical data is limited. Traditional use supports its soothing reputation, but more rigorous studies are needed to confirm its efficacy.
