Hi Sean
There are so many reasons why someone’s face or body might break out with acne. Whether something is yoga related directly or related to the yoga or non-yoga environment or food or stress or ??? would require some investigation.
Have you had a look at other posts about acne? I did a search on the word ‘acne’ and found dozens of references to it in previous posts.
I hope that is a good starting point for you to determine if there is a link (for what I am presuming might be a yogi you may know)
Namaste
Gabrielle 🙂
