After a shave or hot shower should i use cold water on my face to close pores before applying moisturizer? or would the cold water not even matter.

Luke warm water: may be the best bet. Hot water can dehydrate skin. If skin is red - use cool water. Insure you use fresh, sharp blades vice dull blades. If hair is > several mm long – then trim before shaving. Wash area before shaving – warm water helps to soften hair. Use a lubricant when shaving. Avoid using products that contain alcohol or are scented. Shave in direction of the hair – not against it. Be gentle
