You change minor details about your face and hair for the duration, which can include any of the following effects:

• You change your hair color and/or the length of your hair by 10 inches. 
• You change your eye color. 
• You cause a single facial feature of yours to either grow, shrink or change shape (for example, you can make your nose bigger or smaller, or make your eyebrows appear bushier). 

The changes you can make to your appereance are limited to your face only, and you can't change your skin color. Your voice, height, sex and weight stay the same. 

Creatures who know you can possibly tell it's you, and creatures who have seen you before and are actively looking for you can tell it's you by passing a Wisdom (Perception) or Intelligence (Investigation) check countered by your Charisma (Performance) or Charisma (Deception) check. 

The spell lasts for the duration, until it is dispelled, or until you end the spell. Ending the spell requires no action.
