The Sun and Your Skin

According to the United States Department of Health and Human Services, ultraviolet (UV) radiation from the sun and artificial sources, such as tanning beds and sun lamps, is a known carcinogen. So what is SPF and how can it help? It stands for Sun Protection Factor, indicating the ability of the product to deflect UVB rays (short-frequency UV rays), and is the most reliable way to avoid sun damage to your skin. Since sunscreen can range anywhere from SPF 2 to greater than SPF 70, with different UVA (long-frequency UV rays) blocking ability, it can be confusing to know what’s best for you. Regardless of your skin type, the American Academy of Dermatology recommends a broad-spectrum, water resistant sunscreen of at least a SPF 30 with both UVA and UVB protection for daily use.

Sunlight damages our skin’s DNA, causing everything from wrinkles, freckles and skin thinning to cancer. Most skin issues that we associate with aging are actually DNA damage, caused by sun exposure. In our younger years, we have DNA repair enzymes that help combat this damage, but as we age, these enzyme levels drop, leaving us vulnerable. Serums and creams with DNA repair enzymes from natural plant sources like plankton help fortify the natural enzymes in your skin and can have measurable results within hours.

Many ingredients in personal care products, such as fragrance, SD alcohol and chemical preservatives, can increase photosensitivity in your skin; something to be aware of in the height of our summer season. Watch for conditions such as flaking, redness and blemishes; these can all indicate a degree of sensitivity.

Medical-focused dermatological treatments, such as microdermabrasion, acid and laser peels to remove dry, discolored, damaged skin, can help your skin recover from overexposure to the sun. Discuss these options with your dermatologist to ensure a treatment regime that is appropriate for your skin type and your long-term skincare goals.

Look after yourself on a daily basis, particularly as you are outdoors and active, and safeguard against sun damage, sensitivity and more serious conditions. Liberal application of a SPF 30 or greater with both UVA and UVB protection is the best way to give your skin the first line of defense it needs as a fundamental part of your health and well-being.
