What do you say to women who are concerned about their body image?

I have two friends right now who are very concerned about their weight and looks in general. I see two truths here:
1. They both look great and are worrying about nothing,
2. It doesn't matter anyway because they're my friends and I know that they're beautiful inside and out. That has a LOT of attractive potential.

I've told them the second part. I'm hesitant to add the first part because then it sounds like it's about that. 🤷‍♂ I swear, even the most beautiful women over-worry about their looks.
