If a religious person puts on make up it’s usually because they are trying to present themselves in the best way they can. I wear make up so I won’t look tired or ill. Trust me, without it that’s exactly how I look no matter how good I feel or happy I am. Or it is expected of them in the profession they have chosen. Non-religious persons may have very different reasons but they don’t read threads on religious forums.
Actually, if it had been a part of her culture–the kind of thing every woman of her time did, then yes, I could see her doing it and having no more qualms about it than a modern woman choosing which outfit is most appropriate for the occasion. Mary lived in within a different time and culture. To judge such things by her is to set up an unfair example for our times and culture. We should all be modest and humble as she was, but neither of those require that we be drab or mousey.
Make up is a mere tool. Like any other tool it can be a help or it can damage. It all depends on how it is used. This is why the Church makes no judgment about these things except to urge modesty. And modesty deals with the state of one’s soul not merely what one wears or eats or drives or any other mere outward thing.
Considering your poor father’s experience, I can understand your aversion to tattoos. But, tattoos are also neutral things. They can be overdone, and some definitely overdo them. Once again, though most religious people won’t overdo this any more than they would overdo make up or jewelry, so you’re preaching to the choir.

As to getting rid of them, there are procedures and products, but it is hard to do, as I understand it–I don’t have any. In all these things each person has to use prudential judgment based on the teachings of the Church. We need do not more than that, but no less, either.
