I've been in psych hospitals 3 times and residential treatment 3 times and I can confirm that the vast majority of people never go past the dermis (styro) or even into it. I thought my SH was in the low-middle in terms of severity on the spectrum of SH before I went to treatment because I had been so desensitized by forums and shtwt. The staff at my first residential place freaked out, put me on nearly 24/7 supervision, and almost sent me home on my first day because I had a cut down to fat (beans) from a few days before. ER staff and crisis counselors have told me that my SH is severe, but it's nothing compared to what I could see 1000s of times over if I opened shtwt or the self harm scars subreddit. It's so distorted online
