Daily use of sunscreens Dermabellix Review is an excellent way to protect yourself from harmful UV radiation. There are hundreds of products on the market. Look for sunscreens with a sun protection factor (SPF) of at least 15 for everyday use. Products with higher SPF's are also available. Many think that the additional protection of an SPF over 30 is minimal, but we feel that the higher protection factor helps make up for deficiencies of application. All sunscreens are good at blocking UVB, but the only sunscreens that adequately block UVA are those that contain titanium dioxide, zinc oxide, avobenzone (also known as Parasol 1789), or Mexoryl (also known as Ecamsule.) It is primarily UVA that causes skin aging, so be sure to use a sunscreen with at least one of these ingredients. Helioplex is a new ingredient that stabilizes chemical sunscreens and extends their protection to 4-5 hours.There are many sunscreens formulated for the face; these are less likely to feel greasy or clog pores. Many facial sunscreens contain moisturizing ingredients and can be used as an under makeup moisturizer. Sunscreens also come in waterproof formulations which are good for swimming and outdoor activities. Sunscreens should be applied to all exposed areas (face, neck, ears, tops of arms and hands) and ideally should be reapplied every few hours.Don't fall for the idea that tanning beds are safer than real sun. Tanning beds emit mostly UVA, the longer wavelength. We now know that UVA is not "safer" than UVB. Not only does UVA contribute to cancer, but it actually causes more aging changes than UVB! Why pay for all this damage when you can get it for free?There has recently been some controversy about vitamin D, the "sunshine vitamin." Ultraviolet energy from the sun catalyzes the conversion of the vitamin D precursor in the skin to its active form. Vitamin D has been the subject of much research lately and has been shown to have many benefits to human health beyond bone metabolism. Many people are actually deficient in this vitamin, possibly due to use of sunscreens. Darker skinned individuals and those living in northern latitudes are most at risk for vitamin D deficiency. There are different estimates of how much sun exposure is required for adequate vitamin D production, from 10 minutes daily to 10-20 minutes twice weekly. It's not clear that anyone knows the exact answer. In the meantime, it can't hurt to take a vitamin D supplement. I recommend 1000 units of vitamin D3 daily, for adults. Some people take even higher doses.
