What it is
A natural extract derived from the seeds of the longan fruit (Nephelium longana), rich in polyphenols and other antioxidant compounds.
How it works
It donates electrons to neutralize free radicals, reducing oxidative stress on the skin. This helps protect collagen and elastin fibers, and may calm minor irritation.
Pros
Gentle antioxidant
Provides free-radical protection without common irritation, suitable for sensitive skin types.
Soothing potential
Early research suggests it may help calm redness and irritation, adding value for reactive skin.
Cons and cautions
Limited research
Most evidence comes from lab studies; human trials on topical use are scarce, so real-world benefits are not fully confirmed.
Low typical concentration
Often used at 0.1–2%, meaning its impact may be subtle compared to more potent antioxidants like vitamin C.
Best for
- Anyone looking for a gentle antioxidant boost
- People with sensitive or reactive skin who want plant-based protection
Use caution if
- Those with a known allergy to longan or related fruits (lychee, rambutan)
