I find very very strong black sugary coffee is quite good to "prompt" things. I'm badly the other way due to a malabsorption condition and find it horribly uncomfortable to be the other way.
Eating a large amount of protein always seems to go straight through me too, like a lot of mince.
Lactulose is nice and gentle to get things moving if it's not a usual occurrence, you can get it in the bottle over the counter. It's essentially very very sweet so you could try something like a lot of orange juice.
I can't stand the thought of things like figs or prunes.
The best way to get a glowing hydrated complexion is healthy eating and lots of water. If you need a bit of a boost, why not try a facial as good beauticians tend to have a variety targeted to different skin types and results.
