It’s important to increase your use of moisturizing creams and ointments during the winter, applying heavy layers, especially over the skin affected by psoriasis. It is helpful to apply the moisturizing cream while your skin is damp. Also, be sure to pat yourself dry after bathing—don’t rub yourself with the towel.
During the winter months, the humidity is generally lower, especially in homes with forced air heating. This tends to cause dry, itchy skin. Scratching affected skin will worsen your psoriasis and can even cause new lesions to form. Thus, it is important not to scratch, pick, or scrub psoriasis lesions.
