As for the skin tone: (Assuming you're using Photoshop). - Desaturate the photo/skin a little. - Use the rectangle tool to cover the whole photo with a block of colour. - Change the colour of the rectangle so it's similar to this. (You can use that as a colour swatch if you'd like). - Set the rectangle layer to 'Pin Light'. - Change the opacity of the rectangle layer, I usually set it to somewhere between 3% & 10%. Hope this helps.
Love how harsh this image is. Makes it feel real. The composition placing your lips as the focal point is really clever, as the catch light makes those shiny lips inviting , while the underexposure on them makes it scary - love it
