Ingredient review
Prunus Lannesiana Flower Extract
INCI: Prunus Lannesiana Flower Extract
A gentle, antioxidant-rich flower extract that may help calm skin and protect against environmental stress, though research is still emerging.
In plain English
This is an extract made from the flowers of the Japanese flowering cherry tree. In skincare, it's used to provide antioxidant protection (helping to neutralize free radicals that can damage skin) and to soothe irritation. It's a mild ingredient, unlikely to cause problems for most skin types, but it's not a powerhouse ingredient—think of it as a supportive, gentle addition to a formula rather than a star active.

What it is
A natural plant extract derived from the blossoms of Prunus lannesiana (also known as Japanese flowering cherry). It contains flavonoids and phenolic compounds that give it antioxidant and anti-inflammatory properties.
How it works
The flavonoids in the extract help neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. It also appears to calm inflammatory responses in the skin, reducing redness and irritation. In a cosmetic product, it works as a supportive ingredient, boosting the formula's overall protective and soothing profile.
Pros
Gentle antioxidant
Provides mild protection against free radicals without irritating the skin, making it suitable for sensitive skin types.
Soothing potential
May help calm redness and irritation, offering a supportive benefit in formulations for reactive skin.
Cons and cautions
Limited research
Most evidence comes from lab studies; human clinical trials are scarce, so the real-world benefits are not fully established.
Low concentration in products
Often used at low levels (under 2%), meaning its effects are subtle and it works best as part of a broader antioxidant blend.
Best for
- Anyone looking for a gentle, natural antioxidant ingredient
- Those with sensitive or easily irritated skin who want a soothing addition to their routine
Use caution if
- Individuals with known allergies to cherry blossoms or related plants (Rosaceae family) should patch-test first

Research notes
Laboratory studies indicate antioxidant and anti-inflammatory activity, but human clinical data is limited. The ingredient is not a well-studied active, so its benefits are supported more by traditional use and in vitro evidence than by rigorous clinical trials.
