A skin disease like psoriasis is bad enough by itself, but it's made worse by the frequent need to visit your physician just to alleviate the pain and all-too-visible symptoms. Thankfully, Philips has just unveiled a wearable device that will let most psoriasis sufferers treat themselves. Its new BlueControl strap uses its namesake blue LED lights to slow down cell division (and thus painful inflammation) on your arms and legs; in tests, it cut the severity of symptoms in half without any side effects. The light therapy equipment will require a prescription when it reaches Germany, the Netherlands and the UK this October, but it will likely be worth the effort if it helps you avoid the doctor's office and get on with your life.
