Easiest way would be to grab the contents of your “About Me” xprofile field directly in your BP profile template.

Say your xprofile field is called “About Me”:

$about = xprofile_get_field_data( 'About Me', bp_get_the_site_member_user_id() );

Then you can manipulate the $about variable however you want.

Keep in mind you’ll have to apply your own HTML filters if you go about this way.
