I know this is a shitpost but I can't help myself, paralytic drugs also paralyze your diaphragm and only last a few minutes. Pancuronium is the longest lasting paralytic and a single dose will get you 60-90 mins max. Youd spend your time fully conscious while suffocating and be dead before anyone could notice your sweet prosthetic makeup.

Also, you'd still have a pulse and warmth/color to your skin. Paralytics don't stop your heartbeat, and are know to raise it to dangerous levels or cause dysrhythmias if not carefully controlled. So anything more than a passing glance (assuming you lived long enough for it to matter) would immediately give up the game and you'd be defenseless
