Not everyone with PsA has the typical psoriasis symptoms: red, scaly rashes that pop up on your elbows, knees, back, or head. Even if you don’t, dry skin can kick off a flare. Keep skin moist and healthy with lotions with aloe vera, jojoba, or zinc pyrithione as a main ingredient. Apply it regularly, especially after a bath, shower, or swim. If you’re in cold, dry weather, slather on a protective layer before you step outside.
