Should my scars look like this after having microneedling done? (Photo)

Hi, I had dermapen done yesterday and I now look like this. The esthetician said she went over the scar area extra hard with 1.5mm needle as it was scars and that's why it looks so horrible. She said it would settle down. Today it feels a bit stingy and it looks much worse than my original scars. It's almost as smaller wounds and the area around it is very red. Is this normal? Will this leave a permanent mark? I am so so worried and upset. Kind regards
