When I color my eyebrows I use this easy kit from DEPEND to do it with and it only takes a few minutes to do.
I use the brown-black one but there is also brown or black and the best thing is to start with the lightest and then if that doesn't feel ok buy the darker one next time.
This last for many coloring sessions and is to a good price=)
For me, marked eyebrows make us look younger so I try and take care of them.
Lipstick from MAC in orange, my favourite!
