A lot of phones now come with this feature in the default camera app. I had a family member uploading group photos that all had smoothing applied to our skin. They said it made us look better. I found it offensive.
Especially since it just makes you look "worse" by comparison in real life. I've actually had this happen to me: meeting a friend I've only seen online for the better part of 10 years. My brain stalled upon seeing them because I knew who they were, but they just look so much worse than their pictures.
