I want to review again for our patients the importance of sunscreens and the types of sunscreens. It’s well-known that there’s an “SPF” number that supposedly tells the effectiveness of the sunscreen. This number is quite deceptive, and only covers one type of the light reaching the skin, the “UVB”. These sun rays do burn the skin, however there is a probably worse spectrum of sun rays called the “UVA” which causes deep penetration into the skin and ultimately probably cause more aging. These rays can be blocked at this time only by a particulate sunscreen or what’s called a micronized metallic sunscreen such as zinc, titanium, or iron. Fortunately, these tiny bits of metal are small enough to rub in clear and we heavily recommend that you use a sunscreen that incorporates both UVA and UVB protection. For UVB, of course, there are chemicals that have been used for years that are pretty effective, and we recommend sunscreens that have both the chemicals for the UVB and the particulate or “micronized” sunscreen for the UVA protection. One good sunscreen is the Fallene Total Block, which can be purchased at many pharmacies or online. This contains again both the chemical component for the UVB and the particulate component for the UVA. If rubbed in aggressively, many times this is almost a clear sunscreen. Dr. Yoho’s sunscreen has the particulate block which does block both the UVA and UVB, but not as well as the kind with the chemicals plus the tiny metallic particles. It’s excellent for those with sensitive skin and people who don’t tolerate chemicals on their skin. And you’re welcome to try a sample at our front desk. Otherwise, twice daily application of Fallene Total Block will cover all of your needs.
There have been many reports of vitamin D deficiency in the last decade and taking vitamin D is a good idea for most Americans or people who don’t get a lot of sun exposure. The recommended daily allowance is only 1000 IU per day, but we recommend 5000-10,000 IU a day. This certainly will do no harm and probably is the real requirement for someone who has vitamin D deficiency. Some reports have shown that as many as a quarter to a third of Americans has a vitamin D deficiency or near vitamin D deficiency so it certainly doesn’t do any harm to take vitamin D supplements.
