Hi there! So, I think that one is right, and I'll tell you my reasoning: 1) There are actually quite a few ways to say "putting on lipstick / chapstick". Most common is 涂口红 or 涂唇膏, you can also 抹口红, or 擦口红. I think the author chose 摸 partially to describe it as as less of a "smearing" and more of a... dabbing? Probably with the finger? And partially because she was trying to use a different verb than was used in the clause before it (抹了雄黄酒) . 

This is a kind of abstract observation, but I've noticed that in Chinese art and culture, symmetry is extremely important. Left and right should balance each other, top and bottom should set each other off precisely. We see this most obviously in traditional architecture, but it even extends to things like the way the government is structured. And of course it extends to language - if you're going to use three verbs, 抹(雄黄酒), 摸(唇膏), 戴(红线绳), if two of them were the same and the third was was different, this would instinctively feel like bad writing to a native reader. They all should be different, so I think that's probably a subconscious reason the author didn't pick 抹 for this one. 

But, as always, I'm open to correction.
