I travel for business at least every other week and sometimes more often. I don't want to feel deprived so I bring lots of stuff but I manage to keep it within the carry on limits. Here's my inventory....

My TSA baggie contains:
facial cleanser
hair conditioner
hair gel
hair smoothing cream
BHA exfoliating solution
eye cream
benzoyl peroxide acne medicine
toothpaste
facial moisturizer/sunscreen
antioxidant mattifying serum
foundation
eye shadow (cream in a tube)
blush/lipstain
mascara
lipgloss
Tide stain remover pen
isopropyl alcohol (first aid)
hydrocortisone cream
hand/foot cream
saline eye drops
saline nose spray

I've gradually become more and more lax about leaving the toothpaste, foundation, blush, mascara, lipgloss and handcream in my purse and haven't been stopped yet. If asked, I'd have no problem fitting them in the baggie - it's just laziness.

In addition to the stray liquid items mentioned above, my purse contains:
toothbrush
comb
pressed powder
nail file
ibuprofen
Vicks inhaler

My toiletries bag contains:
solid deodorant
baby powder
razor
eyelash curler
eyebrow brush
nail file
nail buffer
nail brush/foot file
Q-tips
dental floss
tampons
hair clips
ear plugs
ibuprofen
benedryl
vitamins
bandaids
moleskin
manicure scissors
sewing kit

Quite a collection! All this stuff lives in these bags so it's not like I'm packing it up every trip - just replenishing things that are running low.
