Take advantage of our “Buy Your Antioxidant/Get Your Sunscreen for FREE” through June at participating Kelsey-Seybold pharmacies Page ContentA few years ago, choosing a good sunscreen meant you simply looked for a high-enough sun protection factor (SPF), which rates how well the sunscreen protects against one type of cancer-causing UV ray, ultraviolet “B” (UVB) since SPF refers to blockage of that particular ray only. Research since then has demonstrated that ultraviolet A rays (UVA) also increase skin cancer risk. While they don’t cause sunburn, they penetrate deeply into the skin, causing cellular damage and wrinkling in addition to skin cancer risk. The Environmental Protection Agency estimates that up to 90% of skin changes associated with aging are really caused by a lifetime of exposure to UVA rays. Today, “broad-spectrum” sunscreens that help protect against both UVA and UVB rays and are widely available. Kelsey-Seybold doctors say daily use of a broad-spectrum sunscreen with an SPF of 30 or above is important. But how do you determine which one is best for you? Turns, out, it depends on your skin type.Physical vs. ChemicalSunscreens help shield you from the sun’s dangerous ultraviolet (UV) rays in two different ways. The molecules in chemical sunscreens absorb UV radiation through their chemical bonds. As the bonds absorb UV radiation, the components of the sunscreen slowly breakdown and release heat from the skin, Physical sunscreens actually reflect UV radiation. Both types are available at most Kelsey-Seybold pharmacies, including both varieties offered from SkinCeuticals®, medical-grade skincare. We will highlight a few of our favorites below. Did you know? If you struggle with hyper-pigmentation issues (brown spots) on your skin, you should know that the process of chemical sunscreen’s release of heat can exacerbate these issues, so you should strongly consider a physical sunscreen. In the past, you may have tried physical sunscreens and found them to be quite thick and perhaps even chalky on the skin. Fortunately, newer formulations are game-changers and come with lighter textures along with tinted and untinted varieties. Physical Matte SPF 50 is great for combination to oily skin. It’s proven to maintain a matte finish, even in humid climates like Houston. Translucent color spheres enhance radiance and an optimized smooth base refines skin texture and minimizes appearance of pores with a powder-dry finish that acts as a great makeup primer as well. Sheer Physical SPF 50 is another physical sunscreen, featuring an ultra-sheer, transparent sunscreen fluid that combines 100% mineral filters with artemia salina, a plankton extract to help boost skin’s natural defenses to UV and heat-induced stress. It offers broad spectrum protection for all skin types, including sensitive. Ultimate UV SPF 30 is a broad-spectrum protective chemical sunscreen with transparent zinc oxide. It’s moisturizing and has a light, cosmetically-elegant feel.
