Is it necessary to buy the sunscreen with the highest SPF? How much more effective is a product with SPF 80 versus SPF 30?
No, it is not necessary to buy the sunscreen with the highest sun protection factor (SPF). You should always wear sunscreen with at least an SPF of 15. Apply 30 minutes before venturing outdoors and reapply every two hours; reapply immediately following swimming or after considerable sweating. SPF of 15 means that your skin is protected 15 times longer from the sun’s harmful ultraviolet B (UVB) rays than without sunscreen. Look for a product that protects against both UVB and ultraviolet A (UVA) rays. The difference in UVB protection between an SPF 100 and SPF 30 product is marginal. For example, SPF 30 deflects 97 percent of UVB rays, while SPF 50 blocks 98 percent and SPF 100 blocks 99 percent. According to the Skin Cancer Foundation, numbers above 50 offer negligible increases in protection. The Food and Drug Administration is proposing to cap the SPF at 50 with strict rating and labeling laws. Until this happens, you will probably see many products vying for the market share with big SPF numbers.
What is the best way to keep your skin radiant during the summer months? Keeping your skin clean, hydrated, and protected will ensure a natural glow. Be sure to use a mild soap; wash the dirt and excess oil from your skin preferably twice a day. Avoid a cleanser that has perfumes or dyes.
Your skin loses a lot of moisture throughout the day due to evaporation. To aid your skin against drying out, drink plenty of water and apply a moisturizer after washing your face. Look for a moisturizer that is water-based with no perfumes or dyes. Check the labels of your favorite lotions and foundations, do they contain sunscreen? Protect your skin from aging prematurely by routinely applying sunscreen with a sun protection factor (SPF) of at least 15. Refrain from smoking, which increases wrinkles.
Dysport® is derived from botulinum toxin A and has been approved for aesthetic use in the United States. It is similar to Botox®—both work to paralyze muscles that contract and cause wrinkles. Botox®, however, is suspended in sodium chloride; Dysport® is suspended in lactose. It takes 10 minutes to inject Dysport®, with results showing in one to two days and results lasting three to five months.
Talk to your doctor to see if Botox® or Dysport® might be right for you. Another new product on the market is Evolence®. This new dermal filler is used to smooth and soften wrinkles by adding volume back into your skin. Results are immediate and last at least six months. This filler is made of an advanced collagen compound; it does not require a skin pre-test. It is recommended for the improvement of moderate-to-deep facial wrinkles and folds, e.g., smile lines.
