Water - I drink a ton of it, and always have. I am constantly thirsty. I always have to have water handy. I don't count my glasses though - I just drink if I'm thirsty. Which is .... always.
My skin - is combo skin... it can get very dry, especially in the winter, but the T-zone area can get oily. You probably notice a sheen to my face in my photos! That is the oily parts. I rarely have breakouts though and it's always been that way, even as a teen. At most, I will get one enormous zit once a month (hormonally and stress related). The oily parts don't bother me so much as the dry parts, so I am content to "shine" a little ... I am Shiny afterall.
Pores - I have gigantic pores, particularly on my forehead and nose. I think they have gotten larger as I've gotten older. You could drive a truck through my pores. But strangely, when I use Biore, nothing gross comes out. So I don't have blackheads at all. Although sometimes the wrong moisturizer can clog up my pores - it will look like whiteheads but it's not really; it's moisturizer stuck in my large pores!
Eczema - I don't have eczema; I have psorasis. I've had it since I was a child; it runs in my family (my dad and brother also have it). It comes and goes. Right now it's mostly in remission; what tiny areas I get, are easily controlled with Rx I have. When it flares up, it can last for a long, long time and be very stubborn. It itches like crazy and is gross to look at, and it can cause secondary bacteria infections that are probably the worst thing about it. It is not caused by any soaps or diet or anything else like that. For me, the trigger is always, always STRESS. Major life stress, not the good kind of stress. For example right after my divorce I had nasty flare-up that lasted for over five years.
Skin-care routine - as a teen and through to my 30s, I kept my skin-care routine very, very simple. I'd use plain old, antibacterial soap to wash my face, and then apply Oil of Olay with SPF. That was it. No exfoliating, no expensive moisturizers, no fancy soaps. In fact, most fancy soaps would give me breakouts. I can't even use Cetaphil - it made me itch and breakout. The worst soap is Ivory. I never understood how people could like Cetaphil and Ivory. Glycerin soaps are okay though. But I always return to something basic and antibacterial, like Lever.
However as I've gotten older (late 30s) my skin has changed and I have a slightly more complicated routine now. I still wash my face with antibacterial soap, as directed by my doctor. Except in the winter I am more apt to use the olive oil instead, since my skin gets so dry. I still use the antibacterial soap once a week though. And now I exfloliate regularly too - it really makes a difference.
Plus, I've been using richer moisturizers. At present moment DH and I have been sharing a Lancome moisturizer that has antiaging stuff in it, and we both like it very much. I don't know if it's making us look any younger, but it's very rich yet not oily and it sure feels nice. It also makes a great base for foundation.
