After you opened your texture in photoshop, save it as a copy. Then add a new layer and paint on that one with a soft brush set to some 50% transparancy and set the blend mode to color. That way you keep the skin structure from the bottom layer. When done, save, then flatten layers and save as jpg or so for Poser. Do NOT overwrite your original file. Add something to the name when you save the jpg. To keep the lips like you want, add a layer mask to your top layer and paint the lips. (only black and white. Try out which one you need. Finding things yourself is good for memory)
