Boswellia Serrata Extract Middel Plant extracts No known benefits Boswellia Serrata Extract description An extract from the gum resin of a tree and also a source of Indian frankincense, this plant extract has both positive and negative qualities for skin. Its fragrant components have the potential to be sensitising. On the flipside, Boswellia serrata also has research showing it has an skin-soothing effect. Clearly there’s some benefit for skin, but there are potential risks, too, just like with lots of other fragrant plant extracts. Related ingredients: Frankincense Extract
