I really liked this technique, using my Albedo layer, and choosing to mask crevices of the image gives you a highly detailed mask over your model that can capture alot of pour and blemish detail that will obviously line up with the albedo perfectly, This plus my underlayer of Pours and skin differences gave a nice worn face.
With bloating the unmasked parts very slightly, you can get pour and hair detail, I found any extra detail now was free detail, and I could soften out anything that didnt quite work.
