I've seen some improvement in my skin overall from taking MSM supplements, which are also good for joints, gums, and other connective tissue. I moved from Texas to England, so I get much less sun, but my psoriasis has improved greatly since I've been here. We live by the sea, so I guess the air here must help. I also have a lower stress job, cut back on alcohol and don't use drugs, and drink a lot of water. All of those things really have helped my skin, so if you can try to eliminate some stress somehow (yoga, stretching, exercise, meditation, whatever works for you) then I really recommend it. If you are having a very itchy outbreak, I would recommend putting ice packs or bags of frozen vegetables on the itchy area and just trying your best not to scratch. It should pass eventually. Sometimes taking Benadryl will also help reduce the itching since it's an antihistamine. Someone I know just recommended putting a few drops of tea tree oil in a carrier oil or base lotion (non-irritating fragrance free lotion for sensitive skin) and applying to the affected areas, but I haven't tried that yet, so I will let you know if it helps. Avoid really hot water, like hot showers and baths, it makes things a lot itchier. Instead, try soaking in a lukewarm or room temperature bath (just warm enough to be comfortable, not hot) with colloidal oatmeal or a good bath oil. Then pat your skin dry, don't rub or try to exfoliate the scales, this only irritates the skin. Then apply a good, thick moisturizing cream for sensitive skin like Cetaphil or Eucerin or whatever you like. You can switch from using scented bath soaps to using Cetaphil cleansing solution or Aqueous Cream instead, as well. Basically, just be gentle with your skin. Psoriasis is really just your body producing more skin cells than you need, so if you damage the skin, it will only cause the scales to get worse, which is why picking and scratching cause more trouble in the end, though I know how good it feels at the time! Whatever you do, don't pick!
