Looks for help in editing makeup for DAZ

Hello,
Does anyone knows how to (or tutorials for) edit makeup, or make our own makep, for DAZ Studio (or Poser for that matter). That will be usefull for tattoos, scars, blood on skin, freckles, etc...
I know it is a question of using any picture editing software like Photoshop in my case. We load the body part and work it in the software, sure. But that requires great skill and some inspiration.
Can anyone share their experiences regarding that?
Thank you.
P.S.: I'll contribute by posting a nice youtbe link on how to make freckles for your models https://www.youtube.com/watch?v=LJvOvFNOaQ8
I used that technique to make Charles in RfJ. Created that brush like in the vid and using PS I painted over the body part texture, face, torso and members.
