Duplicate the laxer, emboss it and then use blending modes like multiply or add to mix it with the original.
Do as Mylenium mentioned. Many of the overlay blend modes (overlay, softlight, hardlight, etc) work well with this.
The layering selections above are good.
Or just use Edit - Fade - Emboss and choose Overlay blending immediately after running the Emboss filter.
Hello, as an alternative, if the object has been put on its own layer, a bevel/emboss layer style alows you to emboss it non-destructively without desaturating the object.
Check the fx icon at the bottom of your layers panel.
