What it is
An extract made from the sprouted shoots of Polygonum multiflorum, a climbing plant native to East Asia. The sprouts are harvested, dried, and processed to concentrate their natural compounds, including flavonoids and stilbenes.
How it works
The extract provides antioxidant activity by donating electrons to neutralize free radicals, which helps prevent oxidative stress that can lead to premature aging. It also has mild anti-inflammatory effects, helping to calm redness and sensitivity when applied topically.
Pros
Gentle antioxidant
Fo-ti sprout extract offers antioxidant benefits without the irritation that some stronger antioxidants (like pure vitamin C) can cause, making it suitable for sensitive skin.
Soothing potential
Early research suggests it may help calm redness and inflammation, which is helpful for those with rosacea or post-procedure skin.
Cons and cautions
Limited research
Most evidence comes from lab or animal studies; there are few well-controlled human trials confirming its effectiveness in skincare.
Potential allergen
As a plant extract, it can cause allergic contact dermatitis in rare cases, especially if you have a history of plant allergies.
Best for
- Anyone looking for a gentle antioxidant to protect against daily pollution and UV stress
- People with sensitive or reactive skin who want soothing ingredients
Use caution if
- Individuals with known allergies to Polygonum species or related plants
