Question: #1
I was just getting ready to purchase some C.O.T.Z SPF 58 sunscreen from your Web site when I realized that it says "sunscreen". I had read on one of the skin care Web sites that you should only use "sunblock" and not "sunscreen" because sunscreen doesn't protect against all harmful rays. Is this true? I would be buying it for my husband who works outside everyday, and it is very important to keep him protected to the fullest with all the sun exposure he gets. I just wanted to make sure this would work for him. Thanks!
Dr. Fuhrman's Answer:
This is definitely the best product for your husband. The words sunscreen and sunblock are often interchanged and not used accurately. Nevertheless, our product offers a powerful degree of protection for those who burn easily and for those who are in the sun a long time or have sensitive skin. It protects against both UVA and UVB and stays on the skin for an incredibly long time. It does not burn eyes and has no harmful chemicals. With the other chemical sunscreens or sunblocks, you have to reapply them every few hours. With ours, it is there continuing to work for most of the day. So if your husband is outside for 8 hours straight, I would use another application after the first 4 hours to offer complete protection.
Question #2:
Today was a gorgeous sunny day, and I went for my first bike ride of the year, covered with COTZ sun block. The purpose of the COTZ was to block out the damaging effects of the sun, but by doing so, I'm wondering whether or not I'm missing the good effects of the sun, such as the exposure required by the body for production of vitamin D. Sun always feels way better when I don't have any sunblock on, as though my body is really craving it. Anyway, when I ride my bike, I'm out for hours and feel like I really need to use the sunblock in order to avoid sun damage, but I'm so good about doing so that I worry about never getting enough unprotected time in the sun to get the vitamin D.
Dr. Fuhrman's Answer:
You are correct that the sunscreen will lower vitamin D absorption, but besides the increased risk of skin cancer, you don't want wrinkly skin around your face and eyes, in the effort to get your vitamin D. I would recommend the sun block on your face and also if out in the sun for prolonged periods. You can get your vitamin D from OsteoSun or from another supplement if need be.
