Crisp Masking edges.. ?

Hi All,

First post here a Z central…

I’ve just started to get in to Zbrush and making way though all the tuts etc…

I have hit a road block on my learning… I have been trying to replicate this sort of effect on a skin of a monster character im designing https://dribbble.com/shots/1274798-Ups/attachments/175640

Where the circle on the skin has a perfect edge…from the different of the blue skin.

I’m guessing I’m not looking around for the right terminology … any pointers in the right direction would be great and much appreciated…
