Microblading should I have it before or after my holiday?

I’m due to have my eyebrows microbladed on the 27th January for 1st treatment but have concerns as I’m going on holiday on the 3rd of February. ive read that you can’t get your eyebrows wet or sweaty as this may effect the healing process. I’ve contacted my technician and she said it should be fine as long as I apply factor 50 sun lotion. I’m just worried as I do sweat when I’m not use to hot weather.
