Oh, scapaflo - estar tranquilo!
I have seldom seen any woman of a certain age with any makeup on the camino. That includes me. I'm way older than you, and on the camino I'm au naturel, and you will be pleasantly surprised to find most women are. On my first camino, I had the same anxieties that you feel. They were gone on day 2. Just to be clear, no foundation, no eye liner, no mascara, no lipstick, no blush, no tweezing. Only sun screen.
So jump in with both feet! You will feel liberated and energized to go forward as your real self! And what I found? The time it takes me to get ready for work here at home: 20 minutes. The time it takes to get ready to walk in the morning on the camino: 3 minutes. The extra time and self confidence: Priceless.
