Dry skin has smaller-sized pores with no sign of blackheads. The skin feels tight and in constant need of moisture and nourishment. Skin that remains flaky may also have eczema or psoriasis, which both cause a ruddy, dry, flaky skin. While these sub-conditions can be complicated, they can be calmed and soothed with the right products. You may also benefit from treatment prescribed by a doctor or dermatologist.
