It's parched, a bit flaky and tired looking, and I'm getting irritated reddish patches from my nose to the corners of my mouth, and on my forehead. I'm starting to get very visible pores - especially on my chin.
I am also developing dark saggy eye-bags and very pronounced fine lines at the corners of my eyes. I look like I've been the victim of a furious cross-hatching attack. 
I know I am very old. (nearly 45)
I know I drink too much alcohol
I know I don't drink any enough water
I know I'm a bit hit and miss with my night-time skincare regime. 
I only wear foundation/full make up once or twice a week, and I've been using Bare Essensuals for about a year, which I love, but lately it seems a bit drying.
What are the things that really truly make a difference? If I stop being hit and miss with my night cream will it actually make any real difference, or not?
