Populus tremuloides bark extract is a sebum regulating, astringent, and anti-inflammatory extract from the bark of the American trembling aspen, Populus tremuloides.
The extract from this bark contains mainly phenolic glycosides similar to those from willow bark: salicin, salicortin, and tremulacin. Similarly to salicylic acid, these have anti-inflammatory effects and are able to reduce the amount of sebum produced by oil glands in the skin.
The entire bark extract is also rich in tannins, which are astringent and give the skin a tightened feeling. They also help to treat small wounds and inflammation.
