What it is
An extract derived from the leaves of Hydrangea serrata, a shrub known for its lacecap flowers. The extract contains polyphenols and other bioactive compounds that give it antioxidant and anti-inflammatory properties.
How it works
The polyphenols in hydrangea leaf extract help neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. It also appears to reduce the production of inflammatory signals in the skin, helping to calm redness and irritation.
Pros
Gentle antioxidant
Provides a mild shield against free radicals without the irritation some stronger antioxidants can cause, making it suitable for sensitive skin.
Calming potential
Early research suggests it may help reduce skin redness and inflammation, offering a soothing effect for reactive skin types.
Cons and cautions
Limited evidence
Most research is lab-based or on animals; there are few human studies confirming its effectiveness in skincare products.
Variable potency
The concentration and quality of active compounds can differ between products, so results may not be consistent.
Best for
- Anyone looking for a gentle antioxidant to protect against pollution and UV damage
- People with sensitive or easily irritated skin who want a soothing ingredient
Use caution if
- Those with known allergies to hydrangea plants (rare)
- Individuals seeking a proven, high-potency antioxidant like vitamin C or ferulic acid
