How do I stop my cat from licking me!

I need some thoughts. I have a lovely, sweet cat - he greets people at the door, sleeps within sight of me all day when I work from home, and will give you a little thank you lick when you pet him. This is the problem. I've noticed that after I apply moisturizer to my face or hands, or lip balm to my lips, it's not one or two licks. He's WAY more interested in licking those areas and much more thorough. I'm basically getting a catbath!

If you didn't know, cat saliva acts as a natural detergent and de-scenter, so when they are cleaning themselves, they're also getting rid of any smells that might be on their fur. I'm sure when he's licking me after my nightly skincare routine it's because he sees me as a stinky kitten that can't take care of itself and, out of affection, is trying to help, but I'm worried about him ingesting whatever is in my products. What should I do, spurn his affection? Let him lick me clean? Help!
