Allow HTML on profile custom textarea fields

Currently we can use HTML in author biography field. But not in custom textarea fields created by us. I’ve tried several codes in functions.php to remove the filter and allow HTML but without success.

One of the codes I’ve tried is:

remove_filter('pre_user_description', 'wp_filter_kses');

But this only works with native biography field, which already allows HTML. Any help?

Thanks in advance!
