What it is
An extract derived from the seeds of Aesculus chinensis, a tree related to the common horse chestnut. It contains compounds like saponins and flavonoids that are believed to have anti-inflammatory and antioxidant effects.
How it works
The flavonoids in the extract act as antioxidants, neutralizing free radicals that can damage skin cells. The saponins may help reduce inflammation by calming certain immune responses in the skin, which can lead to less redness and irritation.
Pros
Gentle on skin
Unlikely to cause irritation for most people, making it suitable for sensitive skin types.
Antioxidant support
Helps protect skin from free radical damage caused by pollution and UV exposure, though not a substitute for sunscreen.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use, not large human trials, so effectiveness is not fully proven.
Potential allergen
As a plant extract, it can cause allergic reactions in rare cases, especially if you are sensitive to horse chestnut plants.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle antioxidant to add to their routine
Use caution if
- Individuals with known allergies to horse chestnut or related plants
