Why does the color of the skin change?
Changes in melanin production can be due to a variety of conditions and some medications. Skin darkening can be due to changing hormone levels or medications, but it can also occur from exposure to ionizing radiation (such as the sun) or heavy metals. Radiation therapy can also cause an increase in skin pigmentation.
What happens when skin is deprived of oxygen?
People whose blood is low in oxygen tend to have a bluish color to their skin. This condition is called cyanosis. Depending on the cause, cyanosis may develop suddenly, along with shortness of breath and other symptoms. Cyanosis that is caused by long-term heart or lung problems may develop slowly.
Does lack of oxygen cause wrinkles?
Hyperoxia may slow formation of wrinkles; Excess oxygen lessens impact of UVB radiation, study shows. Summary: It’s no secret that UVB radiation from the sun causes wrinkles. However, a new study indicates that oxygen may help combat the formation of wrinkles by lessening tissue damage done by UVB rays.
