@Epicenter Wow, very interesting! Thanks for sharing, now I gotta have a character going commando in space...
You could, it'd be a bit hazardous, but not really harmful in the short-term. I'd imagine it'd be the futuristic equivalent of streaking; drunk university theater arts majors "streaking" between parts of their zero-g dance facility instead of taking the hallways like everyone else.
As someone else mentioned, research has shown that the human body just needs a little help to hold together in space - not the full heavy spacesuits we imagined they'd need. The cream (or at least it is applied like a cream) does this once it is ready. You put it on at the beginning of the day, let it "cure" (takes about 30 seconds) and you're good to go. It essentially helps support the human body as well allowing for good joint mobility. Normally it is permeable but "seals up" in vacuum (having to do with the 'cream' being microscopic "platelets" which lock edge-to-edge along body contours with exposure to vaccum, then unlock when there's atmosphere again).
People who are concerned about life support failure would wear the cream then a spacesuit without the gloves (since gloves are pretty irritating to work in). The bare hands would be more than protected by the cream, especially if you put on gloves afterwards.
People often talk about where to put the helmet - I'd imagine that spacesuits beyond a certain tech level (perhaps TL9 and above) would actually have a system (very vaguely) reminiscent of airbags in cars today mounted in the collar. If atmospheric pressure drops suddenly below a certain amount, a set of inflatable "balloons" are deployed around the person's head. The seal of this system may not be perfect since multiple balloons seal at the top of the head but it has to take into account that someone might be wearing their hair long and similar variables of fashion, instead the seal is designed to be "good enough." It is made of transparent plastic and while visibility wouldn't be perfect, it'd be good enough to navigate, read emergency signs and certainly good enough to get to the survival locker and retrieve an actual helmet or find and put on your helmet you left nearby. Air would be fed by a straw, either into the space around your head within the balloons or (ideally) in your mouth.
Similarly, I'd imagine that spacesuits actually would seal with seals that are large in surface area instead of small. Like a modern zipper only has a few millimeters of safety margin and is extremely intolerant of things catching in it. Similarly, modern spacesuits have a series of gaskets and rings which require careful inspection. TL10+ designs would be more like a "double breasted" suit design where the entire overlap surface consists of the seal area. Similarly, gloves for such a suit would be more like elbow gloves with lots of overlap between the wrist end of the suit and the elbow end of the gloves - it's more forgiving this way of clothing, hair, or other items catching in it. The suit would seal using simple effect of the vacuum outside causing the seal areas to swell and stick together.
