How to enlarge (BuddyPress) User profile text?

How can I enlarge the user (BuddyPress) profile text? As you can see in the image, all there is some button on which texts are very small and hard to read. How to fix this?

I would like to share a link but I have the membership plugin enabled so the only way to see user profile is to log in. If it required, let me know so I could grand access...

Thank you for your help.
