Set conditional parameter to not output "dateUpdated" field, when entry is first time created
Here's where I'm going to be more help in theory, rather than code. But maybe something like this? I'm happy to revise if someone sees a typo.    

{# Date #}
&lt;span&gt;
     {{ "published"|t|ucwords }}: {{ entry.dateCreated is empty ? "" : entry.dateCreated|date("d.m.Y") }},
&lt;/span&gt;
{% if entry.dateCreated != entry.dateUpdated %}
      &lt;span class="uk-text-success-alert"&gt;
            {{ "updated"|t|ucwords }}: {{ entry.dateUpdated is empty ? "" : entry.dateUpdated|date("d.m.Y") }},
      &lt;/span&gt;
{% endif %}
{% if entry.expiryDate|length %}
      &lt;span class="uk-text-danger"&gt;
            {{ "expire"|t|ucwords }}: {{ entry.expiryDate is empty ? "" : entry.expiryDate|date("d.m.Y") }},
      &lt;/span&gt;  
{% endif %}
