After years of confusing SPF numbers and sunblock promises, the FDA is adopting new sunscreen regulations. Though the regulations will not be in effect for a year, they promise clear information and precise wording on sunscreen labels.
You will no longer see these terms on sunscreen bottles:
- Sunblock
- Waterproof
- Sweatproof
Instead, sunscreen manufacturers may advertise how long the sunscreen is “water resistant.” Sunscreens are now also required to be broad spectrum. Broad spectrum sunscreens protect equally against UVB and UVA rays. While both types are dangerous, they affect the skin in different ways; UVB causes sunburns and UVA causes wrinkles.
In addition to these regulations, only lotions with an SPF number of 15 or higher can claim to reduce the risk of skin cancer and premature skin aging. Although a savvy consumer will be better protected by these rules, doctors remind sun bathers to reapply lotion every forty to eighty minutes.
We all know that overexposure to the sun causes premature wrinkles, age spots, and other problems, but a lack of sun exposure can also cause vitamin D deficiency which can lead to several serious health problems. Vitamin D is essential for proper calcium absorption and is found in certain foods like fish, eggs, Vitamin D milk, and cod liver oil. Vitamin D is also produced naturally when skin is exposed to sunlight. Just how much sunlight should you get? The key is moderation. Unless your doctor tells you otherwise, aim for 15 minutes of sunlight per day.
