You can convert layer effects to actual layers by choosing Layer > Layer Styles > Create Layers. Not all effects can be reproduced as layers so you will see a warning box. If you only want to create layers from some of the effects, make a duplicate of the layer, hide the effects you do not want, then create layers.
