hmm... well it feels like my features are popping out more and that I'm being looked at more:P honestly the only thing i 'feel' is dolled up. sometimes it's annoying tho. u know those moments when u really wanna rub ur eye? if i even touched my eye id end up looking like a racoon-.-
Depends. It's usually the foundation or powder that adds the weight to your face. Wearing heavy foundation and powder like MAC feels heavy on your face but you could buy a foundation at MAC called "Face and Body" which is a water-based foundation that feels very light on your face and makes your face breathe. The coverage isn't that strong though.
False lashes make your eyes feel a bit heavier as well as lipstick with lipgloss.
