Dr. Mehmet İlteber Bahadır emphasizes the fact that psoriasis loves dry skin and cold air. In cold weather the rate of sweating and oily on the skin decreases. The skin cracks and this is the main reason for the increase in the lesions of psoriasis patients during the winter months. As we have stated in our previous programs and articles psoriasis patients have to use various body lotions and oils that are indispensable after their baths between november and may when the weather starts to become cool that is sweating in the body decreases and the skin fat ratio decreases. If it possible the creams they use should be liquid easy to spread and contain natural herbal oils. By changing the brand or type of cream they use at least every 2 months we can ensure that the skin becomes stronger with different oils. These are the conditions that psoriasis patients should do for a better quality of life.
