In most cases, your primary care doctor or dermatologist will be able to diagnose psoriasis by examining your skin. However, since psoriasis can look like eczema and other skin diseases, diagnosing it can sometimes be difficult.
If your doctor isn't sure whether you have psoriasis, he or she may order a biopsy. Your doctor will remove a small sample of your skin and have it looked at under a microscope.
Wouldn’t it be nice if your psoriasis would take a hike when you take a trip? Even though you can’t leave home without it, you can safeguard your skin against flare-ups and make sure it takes a back seat when you travel.
