Some of this may sounds weird, and I guess it kind of is, but here's what worked for me.
One important thing to note is that it may be where you live...and whats in your water. I'll get to this at the end, but first...the most important thing is good overall health. A while ago I took acutane for sever acne; though, I didn't have any redness. It messed up my skin and health pretty good so I got desperate to improve my appearance. Creams, lotions, soaps, etc did nothing. So then I turned to improving my overall health.
I cut out all junkfood and tried to get as many things all natural or organic as possible, specifically vegetables where the pesticides and things are sprayed directly on the part you eat (ie spinach leaf vs corn which is in a husk). Replace most of your drinks with green/white tea (same plant) and drink a lot of water. Use a water filter (a good one, not typical brita type filters). You'll find yourself craving variety and wondering what to eat, which is good because now you need to figure out which nutrients you are lacking. This is the biggest thing to get right, this is what will give your skin the evasive glow that most people seek. Even most 'healthy' people are deficient in some areas, but you won't be! At the time I used The World's Healthiest Foods: Food Advisor and the information on their website to figure out what foods I needed to add to my diet. Some nutrients are surprisingly difficult to get enough of! Food by itself is not enough though, you also need to exercise and sunshine(not too much).
Find ways to exercise throughout the day to keep your body and heart from getting too relaxed. This little bit of exercise will prove surprisingly effective in improving the way you feel and keeping your heart rate above normal for the whole day. Whenever you get to stairs do some calf raises, when watching TV do push-ups, when bored ride a bicycle around a neighborhood for 15 minutes (if you live in one). etc.
After sweating RINSE off in the shower then take a warm bath for about 5-15 minutes, until you see the redness in your skin fade a bit. You'll learn the optimum amount of time for reducing or increasing skin redness. Get your head under the water. Too long in the tub increases redness for me (temporarily of course). Get out of the tub when your skin looks its best, for me about 10 minutes. Then pat dry the wettest parts of your body, ignoring the rest. Now cover your body in an oil like jojoba or almond oil (don't do this if you have to go somewhere later that day). Leaving yourself a bit wet allows you to spread the oil on a bit thinner so you don't end up so greasy. You'll notice skin improvements quickly doing this on a regular basis. Downside is that it takes a while to get used to being slimy. Stand around until the little bit of water that's left has evaporated. You may have to rub your hands all over a 2nd time to even out the oil coating. Rinse off in the shower after 2 hours if you oiled too excessively, which you will starting out. Have a second pair of loose fitting gym clothing to wear while oiled up, or go naked if you can I guess. I prefer having windows open. Before you go to bed, if you're not oiled up already or whatever, wash your face without using soap (unless you got sweaty or dirty) and apply some jojoba or w/e you find to be your favorite organic plant oil. This made a HUGE difference on the skin on my face VERY quickly. Works best if you can sleep on your back for obvious reasons.
After doing all of this for a mere 2 months my skin was the nicest it had ever been, as nice as most photoshopped magazine cover models. Nice enough to get uncomfortably long stares from girls who were likely jealous. But then I moved somewhere with water so toxic it should be illegal. I can no longer do the bath thing or even shower because of it. (I have to sponge-bath using water from a fancy filter.) After a few months my skin was so damaged that I couldn't exercise without the salt in my sweat burning my cheeks. I now have redness that I can't get rid of, and mild skin discoloration on my forearms, thighs, and face because of the water here. And I assume the arthritis I developed after being here only a year is in part due to the inflammatory water and air pollution. Yes, I need to move.
TL;DR Exercise a bit, you don't have to kill yourself in the gym. Eat a diet that gets your body large quantities of ALL of the nutrients your body needs. Personally, I noticed that actual food worked far better than supplements. Oh yeah, replace much of your meat intake with fish. Don't use soap unless you're actually dirty (this sounds gross, but you'll be surprised), but still use a washcloth lightly or something. Go ahead and shampoo your head/armpits lol. Soaking in a tub followed by oiling yourself up with botanical oils is a must do for healthy skin. Put a small amount of your favorite oil on your face before you go to sleep; you're not greasing up a skillet. If you live somewhere with terrible water, or even bad air, then you won't be able to eliminate the redness completely.
