There are many ways to improve skin texture in Photoshop. One way is to use a filter called “Bumpmap.” This filter creates a bump map of the image, which can be used to create more realistic skin textures. Another way to improve skin texture is to use a shader called “Specular.” This shader can be used to create more realistic highlights and shadows on your skin. Finally, you can use a technique called “Luminex” to add lightness and darkness to your skin. These techniques can help improve the appearance of your skin and make it look more realistic.
