A team of researchers from the University of California has found that sunscreen can do more harm than good once it soaks into the skin. The sunscreen is supposed to be applied as a layer on the skin. When it is rubbed in, it penetrates to the deeper layers and promotes formation of harmful compounds. Thus sunscreens ironically cause the same damage against which they are meant to protect. Further, the chemicals present in commercial sunscreen products have also been found to be toxic and said to actually promote some forms of cancer.

UVB rays are responsible for creating vitamin D in our body. Sunscreens with a sun protection factor of 8 or greater will block UV rays that produce vitamin D. There is a growing body of evidence that a higher intake of vitamin D may be helpful in the prevention and treatment of cancer, high blood pressure, fibromyalgia, diabetes mellitus, multiple sclerosis, and rheumatoid arthritis and other diseases. So, sunscreen may be blocking the very thing that is keeping you healthy in the first place. Read more on my blog:
