It works for some. Great examples here via ImNotBarbie and below.

Not for all. Sadly, I’m in the Not camp. Without lip color, I look like a cadaver.

I asked makeup pro Raychel Wade for insights.

“I love a nude lip!  Personally it’s my favorite look.  And if fact, often times it can make you look more youthful.  I know that some people feel like a corpse with it on, so here’s a trick.  Pull your bottom lip out and match a lipstick the inside skin color of your lip.  Weird, I know.  But if you feel too pale in a true nude this will give you a close, natural option!”
