INCI: Macrotomia Euchroma Root Extract
A gentle, plant-derived antioxidant that may help calm skin and fight environmental stress, but research is still early.
In plain English
This is an extract from the root of a plant called Macrotomia euchroma (also known as Arnebia euchroma). It contains natural pigments called shikonins that give it a deep red or purple color. In skincare, it's used to provide antioxidant protection—meaning it helps neutralize free radicals from pollution and UV exposure—and to soothe irritated skin. Think of it as a mild, natural helper for skin that feels stressed or sensitive.

What it is
A root extract from the Macrotomia euchroma plant, rich in naphthoquinone pigments (shikonin and derivatives) known for antioxidant and anti-inflammatory activity.
How it works
The shikonin compounds in the extract scavenge free radicals, reducing oxidative stress on skin cells. They also inhibit certain inflammatory pathways, which can help calm redness and irritation when applied topically.
Pros
Natural antioxidant
Helps protect skin from free radicals caused by pollution and UV, which can lead to premature aging.
Soothing potential
May reduce visible redness and calm irritated skin, making it a good option for sensitive skin types.
Cons and cautions
Staining risk
The deep red pigment can temporarily stain light-colored fabrics or even the skin if used in high concentrations.
Limited research
Most evidence comes from lab studies or traditional use; there are few well-controlled human trials confirming its benefits in skincare.
Best for
- People with dull or stressed skin looking for antioxidant support
- Those with occasional redness who want a gentle soothing ingredient
Use caution if
- Anyone with known allergies to plants in the Boraginaceae family (e.g., borage, comfrey)
- Those who prefer colorless products to avoid potential staining
