Okay, I learned here, and it's incredibly easy to make only certain areas of the skin wet (or have any effect you want).
1. Create a geoshell around the figure.
2. In the geoshell offset, choose the appropriate value, which will depend on whether there are other geoshells in the figure or not. I left it very close to the figure's geometry.
3. Apply a shader of your choice. In my case, I applied "Daz Uber: Water".
4. In geoshell parameters, turn off all regions that will not be affected. In my case, I only left the face and lips turned on
4. Now you make a mask based on the figure's UV. I found the texture of the face of the model I'm using, created a new layer in GIMP, and painted the central part of the face white, the dry area, black. I made the transition from white to black subtle so that you can't see the border between dry and white, and that's it.
5. Finally, just go to the geoshell surfaces, find the right location (in my case, face and lips), and in "cutout opacity" apply the mask you just created.
