Nope. It goes away on its own; nothing to do about it -- or at least, not much worth doing, as it doesn't bother the baby and is gone in a couple of weeks. All my kids had it.
Not sure how often you're washing his face, but I'd say unless he's spitting up a lot he doesn't need to be washed. Babies keep themselves pretty clean the first few weeks with no washing at all except to clean up dirt -- spit up, dribbling, diapers.
definitely just let it be. My kiddo had AWFUL acne. It went away on its own. Just wash with water and if you feel baby needs some sort of moisturizer, use a natural oil instead of baby lotion. I prefer coconut oil and my husband is better with olive oil.
Otherwise, its totally normal and just part of the first days and weeks (or in my kids case, months... ) and irritating skin is really easy at that time.
Mine also had it, on and off, sometimes really badly, for about the first 2 months. I didn't use anything on it, just rinsed his face with water when we bathed him. It looks terrible I know, but it'll clear up on its own so no worries.
