I'll be focusing on the lips, manipulating effects and layers to recolor, and add gloss and liner to the lips.
The image I will be working on is from Editable Photos
3. Create a new layer with a darker color than the first. I created a purple layer, and set the blending mode to Hard Light
When you add a Gaussian blur, you get the following:
It's a nice golden-peachy shade, but still not quite what I'm looking for.
5. Create a new layer, and fill the lips in with the same darker color. Set the layer to the Color Burn blending mode at 50% opacity, and move it under the initial pink color layer. You can make the color lighter or darker by adjusting the opacity of the Color Burn layer.
After a little bit of cleanup, you get a nice, mauve color with gold highlights. Perfect.
Lip Gloss and Line:
Ok, back to the original image with the blue lips (it makes the effects that I'm showing pop more).
We're going to be using layer effects to add gloss and liner to the lips
1. Color in the lips with your closest approximation of the original color
3. Go into effects and add the satin effect to the lip color layer
Final result after cleanup:
