Hi there,
Threads used in threadlifts are usually supposed to be placed in the subcutaneous layer (just below the skin layer).
Dents in threadlifts are caused by a part of the threads engaging or “clutching” onto the skin layer, pulling it inwards, causing that part to have a “sucked in” effect.
That is why you can see horror pictures online of patients having many dents on the face after a face threadlift by inexperienced doctors.
Applying this theory to nose threads, any dent would usually be seen immediately during or after the threadlift. If it “suddenly” occurs, it is likely the other end of the thread (either at the nose bridge or the columnellar) has loosened off, or the offending thread was too long to start with.
You will need immediate attention to subcise the dermis/epidermis off the offending thread to prevent permanent dimpling.
Hope that helps!
Best Regards,
Dr Isaac Wong
