Undaria Pinnatifida ExtractBarrier
Wakame seaweed extract. A sugar purified from it, fucoidan, helped a damaged skin barrier recover faster in mice.
What it does
It contains fucoidan, a sugar from the seaweed. In one study, a gel of purified fucoidan helped tape-stripped mouse skin rebuild its barrier faster, raising two barrier proteins and a signal that tells skin cells to mature. That was mice and skin cells, with purified fucoidan rather than a whole extract; no people were tested.
The evidence, graded
emergingIn one study, a gel of fucoidan, a sugar purified from wakame seaweed, went on mouse skin after its outer layer was stripped with tape. The barrier recovered faster than with the plain gel, and two barrier proteins rose. In skin cells, fucoidan raised a calcium-sensing receptor that tells the cells to mature. The study tested purified fucoidan, not a whole wakame extract, and no person.Chen 2019 · Mar Drugs ↗
