Yeah, saturation (or a higher contrast LUT)
The character also looks to have a bit of an outline, this could be achieved with a fresnel shader effect (at least so most edges of the character have a bit of outlining effect to them), or with an image editing program. I explain a similar effect
here, but for the above image you might want to match the outline with a mild dark red, desaturated background.
Now the breast look to be a bit paler than the more redder hues of the shoulders and hip area, this is typical of daz textures, I don't know which texture they are using exactly. Most daz textures have a lot of freckles and 'dirt' to make the skin look less perfect and more realistic, I don't think I have seen a texture this clean of these natural blemish detailing, the cleanest I have is Tess but that tries to be a cartoon character. I would really like to know what texture is being used since I want to do more toon like toon characters and most daz textures look terrible on toony styles.
