Thanks. Glad you like the result.
I used the pen tool to select the lips, refine edge to slightly smooth/feather the selection, jumped to a new layer. Topaz Denoise works nicely to soften the coarse texture. I used the burn tool to darken the edges and H/S to set the color tone, dodge tool to selectively brighten the highlights. On a new layer, with a white splatter brush tip (adjust roundness to make it wide), I make a short stroke, slight vertical motion blur, warp to fit, adjust opacity for extra gloss. Finally, in this case, I overlayed a copy of the original, set to luminosity blend with reduced opacity to retrieve a bit of the original texture. Sounds complex, but can actually be done rather quickly and the adjustments made in the various steps allow a considerable range of end results.
