Ingredient review
Mangosteen Bark Extract
INCI: GARCINIA MANGOSTANA BARK EXTRACT
Mangosteen bark extract is a gentle antioxidant that may help calm skin and fight environmental stress, but research on its topical benefits is still limited.
In plain English
Mangosteen bark extract comes from the bark of the mangosteen fruit, a tropical fruit known for its thick purple rind. In skincare, it's used as an antioxidant to help protect skin from damage caused by pollution and UV rays. It also has some soothing properties, which may help calm irritated skin. However, most of the research on mangosteen focuses on the fruit's rind or whole fruit, not specifically the bark, so its benefits are less well-studied.

What it is
A natural extract derived from the bark of the mangosteen tree (Garcinia mangostana), rich in compounds called xanthones, which are known for their antioxidant and anti-inflammatory activity.
How it works
The xanthones in mangosteen bark extract help neutralize free radicals—unstable molecules that can damage skin cells and accelerate aging. By reducing oxidative stress, it may help protect collagen and elastin, and calm redness or irritation.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, making it suitable for sensitive skin types.
Soothing potential
Early research suggests it may help calm redness and inflammation, which can benefit those with reactive skin.
Cons and cautions
Limited evidence
Most studies focus on mangosteen rind or whole fruit, not bark extract specifically, so its topical benefits are less proven.
Lower potency
Compared to well-studied antioxidants like vitamin C or green tea, mangosteen bark extract may offer weaker protection.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with sensitive or reactive skin who want calming ingredients
Use caution if
- Those with a known allergy to mangosteen or related plants
Usage tips
Safety summary
