Sea Mayweed Extract
INCI: Tripleurospermum maritimum extract
A gentle, chamomile-relative extract that may help calm irritated skin and provide antioxidant protection, though research is still emerging.
In plain English
Sea mayweed extract comes from a wild coastal plant that looks like a daisy and is a cousin of the chamomile used in teas. In skincare, it's added to help soothe redness and protect skin from environmental stress. Think of it as a mild, natural calming ingredient, similar to green tea or chamomile, but from a plant that grows by the sea.

What it is
An extract derived from the flowering tops and leaves of Tripleurospermum maritimum, a perennial herb found along sandy coasts in Europe and North America. It contains flavonoids and essential oils that give it anti-inflammatory and antioxidant activity.
How it works
The flavonoids in sea mayweed extract help reduce the production of pro-inflammatory molecules in skin cells, which can calm redness and irritation. Its antioxidant compounds also neutralize free radicals from UV and pollution, helping to protect the skin barrier.
Pros
Gentle soothing action
Sea mayweed extract can help calm redness and irritation without the harshness of some active ingredients, making it suitable for sensitive skin.
Antioxidant protection
Its flavonoid content helps defend skin cells from free radical damage caused by UV and pollution, supporting overall skin health.
Cons and cautions
Limited clinical evidence
Most research on sea mayweed is preliminary or based on traditional use, so its effectiveness in skincare is not as well-documented as ingredients like niacinamide or green tea.
Potential allergen for some
As a member of the Asteraceae family, it may cause allergic reactions in people sensitive to ragweed, daisies, or chrysanthemums, though this is rare.
Best for
- People with sensitive or easily irritated skin looking for a mild soothing ingredient
- Anyone wanting a natural antioxidant boost in their routine
Use caution if
- Individuals with known allergies to Asteraceae/Compositae plants (e.g., ragweed, daisies, marigolds) should patch-test first
Usage tips
Safety summary
Sea mayweed extract is considered safe for topical use in cosmetics at typical concentrations. The main concern is a rare allergic reaction in individuals sensitive to Asteraceae plants. Patch-testing is recommended for those with known plant allergies.
Research notes
Research on sea mayweed extract is limited. In vitro studies show anti-inflammatory and antioxidant activity due to its flavonoid content, but human clinical trials are lacking. Its traditional use as a soothing herb supports its cosmetic application, but more studies are needed to confirm efficacy.
