ASA One of the main ways the human body conserves heat is through vasoconstriction. Vasoconstriction is
The widening of peripheral blood vessels, bringing more blood near the skin's surface
The narrowing of peripheral blood vessels, keeping blood away from the skin's surface
The narrowing of central arteries and veins, keeping more blood away from the body's core
The widening of central arteries and veins, keeping more blood closer to the body's core

So if you think of it, if you were to increase your blood pressure then wouldn't the blood draw closer to the skins surface?

For example, when your exercising, your blood pressure sky rockets because of all the movement being done and that's why in some people with more visible skin, their cheeks show red. When the skin is red from obvious reasons other than a skin rash after a work out, it's because the blood is so close to the skins surface.
