I have very visible red pores on my legs. What causes this and how can I reduce the appearance?

Shaving your legs with warm water can open up the pores. It could also be dead skin cells or hereditary. After you're done shaving your legs, wash your legs with cold water to close the pores. You can use a toner to tighten the pores. There's a product called Pond's Cool, Calm, & Perfected Pore-Shrinking Gel Toner. It's designed to shrink pores. If you can't find it, you can use another toner like it to minimize the pores.
