Login Redirect

In the config section of the file where we can put the url path to where we want the login to be redirected, I was looking to redirect the login to the Logged In Members' profile page. So if some one could help me in that issue that would be appreciated.

Below is the code I m referring to:
$login_redirect_url = 'http://domain.tld'; // the url you want users to be redirected too after logging in
