Their max health is reduced. If an enemy had 100/100 health, after taking Scarier Face it will have 80/80 health. They are considered to still be full on HP.

How other things like Plant's Throne Butt or Crowns interact with this should be explained on their pages. My comment above about Plant is a little old. Check Plant's page to find out how it works now.
