4. Pale or Lifeless Skin Tone
The skin is the largest organ in the body, and it requires sufficient oxygen flow within the body to maintain a healthy appearance. With diminished hemoglobin production, the skin loses its luster and glow, and begins to take on a lifeless, grey tone.
Iron deficiency affects the skin in many different ways. Blotchy, discolored, or dry skin are all examples of skin disorders that occur due to a lack of iron and low hemoglobin production. Check the inside of your gums and lips; they should be a natural red color. If you notice that the coloring is less red and looks grey or ashen, you could be suffering from low levels of iron.
The skin is a useful marker to monitor treatment of your iron deficiency. The first place you will notice the recovery is in your face and skin tone as levels of iron rise to a healthy balance and hemoglobin production restored to optimal levels.
