All of Kevyn Aucoin's books are phenominal. There are 3 instructional/portfolio-like books titled as follows:
The Art of Makeup
Making Faces
Face Foward
There is also a 4th book which is a tribute to Kevyn titled: Kevyn Aucoin: A Beautiful Life, but it's not as informative on technique but a great book if you admired him as an artist, as many of us do.
