In addition to actually bleaching things, H2O2 has vasoconstrictive properties which can sometimes cause the appearance of skin being bleached. Whenever I apply pharmacy-grade hydrogen peroxide to my skin it causes a temporary 'bleached' effect that fades after a few minutes. This is apparently a matter of small blood vessels near the surface of my skin being constricted. Wikipedia doesn't mention this effect but it's not too hard to find sources on (https://pubmed.ncbi.nlm.nih.gov/860154/). I'm not sure if large exposures could cause heart attacks though this effect, I suppose chemical burns would be the more immediate concern, but it's certainly not something I'd want to find out first hand.
Unfortunately for my morning commute (which is not happening again anytime soon anyway), their HTP jetpack has about 20 seconds of flight time and, fortunately for society at large, you can't get HTP at a gas station.
