What it is
An extract from the sea aster plant (Aster tripolium), a halophyte that thrives in saline environments. It contains flavonoids, phenolic acids, and other compounds with antioxidant and anti-inflammatory potential.
How it works
The extract's antioxidant compounds help neutralize free radicals, which are unstable molecules that can damage skin cells. Its anti-inflammatory components may also help reduce redness and irritation when applied topically.
Pros

Low irritation and comedogenic risk make it suitable for sensitive and acne-prone skin types.
Antioxidant support
Helps protect skin from free radical damage caused by UV and pollution, which can contribute to premature aging.
