Blanket bonding??

Hi everyone, I recently saw a post on Instagram where someone said they were using "Blanket bonding" to get comfortable with their chin. I personally have never heard of it before and didn't find much info online. I'm just curious if anyone has an opinion or any kind of info about it? (It it safe, a good idea, eat)
Also, if this is posted to the wrong forum let me know and I'll post in the proper spot. Thanks!
