A free mod for Witcher 3, by CurtiSRustY.

Real Witcher Eyes – Geralt is a modification for the game The Witcher 3: Wild Hunt. It is a mod that changes the appearance of Geralt and all other Witchers. You can also choose the skin color, hair, beard, eyebrows, and even adds a tattoo of your character. 

This mod will not change the gameplay of the game. All the missions and quests will remain the same. The only thing that will change is the appearance of the characters. The developers have thought of all the players. They have taken into consideration the fact that some players might want to change the appearance of their characters. This is why they have included the ability to change the appearance of the characters.
