It tends to have a shorter duration when the player is running or engaged in combat because of the sweat produced.

Camouflage Makeup Kit- Increases Sneak, Guns, and Energy Weapons
War Paint- Increases Melee and Unarmed
Perfume/Cologne- Increases Barter and Speech
Sounds pretty cool and feasible, yes?
