Alaria Esculenta Extract
Alaria Esculenta Extract
A brown seaweed extract used as a conditioner.
What it does
It comes from Alaria esculenta, a brown seaweed also called dabberlocks or winged kelp. The EU lists it to condition hair and protect skin; that describes what makers intend, not a tested effect on skin.
The evidence, graded
expert consensusUS safety reviewers (2026) assessed 82 ingredients from brown seaweeds, which products use most often to condition skin. They judged 68 safe as used, Cladosiphon okamuranus, Fucus vesiculosus, Laminaria ochroleuca and Alaria esculenta extracts among them, and found too little data to judge the other 14. They noted that heavy metals, arsenic and pesticide residues may be present, and asked makers to keep them low.Ferguson 2026 · International Journal of Toxicology ↗
