Willow Bark vs Salicylic science
I see manufacturers suggest willow bark extract as a “skin purifying” ingredient, mentioning how it turns to BHA.
Am I not correct that the extract only has salicins, and although the body can convert those to salicylic acid, there is no proof this happens in the upper layer of the skin? So it is not a replacement for BHA salicylic acid, it’s just an anti inflammatory rather than a pore purifying ingredient. This marketing claim just doesn’t make sense. Or did anyone have experience with this extract doing anything to clean the pores?
