Did your vet mention anything about acne? Both Duke and R.J. had major acne at about the same age. Duke's lasted a few years, and R.J. still has the odd flare. I would continue with the ointment, unless it looks like your guy is reacting to it. Make sure his food and water are both in either a stainless steel or ceramic dish. Also, give his dishes a good scrub daily with a mild soap and hot water. It also helps to gently wipe his face, after he eats, with a warm wet cloth. If it appears to get worse, or he starts to act like he feels unwell, take him back to the vet. Good luck!
