To shave or not to shave? For many people with psoriasis, that’s the question. And to some degree, the answer is both—when your skin is flaring, there are some areas you'll want to avoid shaving, and others where it may be okay, as long as you're taking certain precautions.

When you have psoriasis, your skin can be sensitive, says Sabrina Barata, M.D., a board-certified primary care physician at Mercy Personal Physicians in Lutherville, Maryland. And then shaving can cause significant irritation.

For instance, if you nick your skin while shaving, you could make your psoriasis worse, says Paul S. Yamauchi, M.D., Ph.D., a board-certified dermatologist at the Dermatology Institute & Skin Care Center in Santa Monica, California. “There is a skin phenomenon called koebnerization whereby injury to the skin can trigger psoriasis,” Yamauchi says, noting that injuries can include cuts, scrapes, abrasions, and burns. “The inflammation that results from injuries aggravates the skin and can cause an immune reaction that triggers psoriasis.”
