Pores can be kept clean if washed daily, by using a soft facial cleanser versus the usage of deodorant soaps. Whenever heading for the pool or a day out in the sun, never forget to protect your skin from hazardous Ultraviolet (UV)rays. By overexposure to Ultraviolet rays, you’re more likely to develop cancer.
