I have been through real problems with this myself and finally figured out a good inexpensive system through trial and error.
First, he should change and wash his pillowcases at least once a week, in warm or hot water, more often if possible.
Then, I most highly recommend that he wash his face twice daily with this:

Sounds crazy, but a dermatologist recommended it, and once I tried it, I never looked back. It costs a bit, but you only need about a dime sized squirt so the bottle lasts a long time.
Last, try giving him 1000 mg of vitamin C twice a day. It speeds healing, and makes your body chemistry slightly acidic, which inhibits bacterial growth.
Hope this helps!!
