formula to increase melanocytes

[Troya]

This fascinates me: there are some patents online on increasing melanocytes ( darkening hair and skin) It's already often done by injecting ( melanotan) but it looks like alternatives are more practical.

This one for instance:

I'm a redhaired person, light skin, I dislike both of them, so maybe anyone could help to put this patent into a formula? looks like it's possible, I'm just not a scientist
