Yes, the skin breathes. It regulates body temperature by allowing heat to escape, mostly via the scalp. Oxygen, the life force taken in by the lungs of our body, is required to sustain optimal skin respiration. When oxygen supply to the skin is restricted, the skin becomes asphyxiated, and takes on a sallow pallor. It loses the healthy pink tone that is an indicator of good circulation.
Smoking is the biggest culprit that limits oxygen supply.
It constricts capillaries, inhibiting blood flow and skin can take on an unnatural yellow-green cast. There are specific types of jobs that contribute to impaired oxygen supply. Airline personnel, such as pilots and flight attendants, surgeons and other medical staff that wear surgical masks. Also office jobs where the windows may not be opened and the air is constantly recirculated. Discussion exists regarding whether cosmetic ingredients actually penetrate the skin.
