Pretty Face is a mod that replaces the textures of faces for human female and male characters in the game, Skyrim. The concept is that of a flat, smooth face, with a little bit of realism. It is designed to look good on all types of characters. The idea is to have a character that looks good and feels good.
It is not an official mod from the developers of the game, nor is it affiliated with them in any way.
An optional requirement for this mod is the SKSE that needs to display makeup files at high resolution.
