FDA Issues New Sunscreen Guidelines 2013

FDA Issues New Sunscreen GuidelinesWe've noted here before to avoid the use of spray sunscreens as well as those that use heavy fragrance. New FDA guidelines for 2013 add to this mix and try to clarify issues with mislabeling or false claims made on the packaging of some sunscreens. So with many people taking a short vacation, or if you're like me, heading to the beach for the weekend, now is a good time to review what the changes are and what are some good guidelines for selecting and using sunscreen.

Modern sunscreen consists of a variation of zinc oxide. Though not as common as in the past, many will remember the white line of sunblock that men used to put on their noses while at the beach. Today, there are lotions, spray and even powders (though they should have been removed from shelves by last December) that people use to block sun and harmful UV rays. With so many choices it can be difficult to decide which sunscreen is right for you and in many cases, what is even effective.

FDA guidelines approved last December work on two primary issues. First, the FDA addresses "broad spectrum" protection. Almost all sunscreens blocks UVB light, as this is the type of ultraviolet light that causes sunburns, but UVA also damages skin. UVA has been shown to cause cancer as well as prematurely age skin, so the FDA has mandated to manufacturers that they can only market their product as "broad spectrum" if it blocks both UVA and UVB light.

Summer Sun & Sunscreen TipsFor beachgoers, a waterproof sunscreen has been the product of choice, but recent findings show that there is literally no such thing as "sweatproof" or "waterproof sunscreen." Some sunscreen can be water resistant, but all sunscreens, after a given period of time, will wear off. Manufacturers are now required to use the term "water resistant" and note the duration of protection, i.e. Water Resistant (40 Minutes). Many people mistakenly believe that if they've applied sunscreen, they are good to go for the rest of the day. Sunscreen wears off, period. It needs to be reapplied throughout the day, typically every couple hours, and sooner if you are swimming or sweating.

Though the new guidelines are a good step in the right direction, the FDA has yet to make any new guidelines on SPF numbers or the use of aerosol sunscreen. Research shows, and your dermatologist will recommend, that you use at least SPF 15 sunscreen but SPF higher than 45 is likely just a waste. We often think more is better, but in the case of sunscreen, there is no evidence to support that. SPF 30 sunscreen blocks about 97% of UVB rays, while SPF 45 blocks 98%. So for now, stick with a properly labeled SPF 30 or 45.

As we mentioned last summer, it is probably best to continue to avoid the use of aerosol sunscreen. When a sunscreen becomes aerosolized, it can be inhaled. There is nothing is sunscreen that should be inhaled, and many of the ingredients can be particularly harmful for delicate lung tissue.

In general, keep an eye out for the new labeling requirements. Stick with a good SPF 30-45 that uses no "fragrance." Be sure to reapply at least every 2-3 hours, and avoid the aerosols. Lastly, many of us generally only use sunscreen while at the beach, and since this can be a summer only activity, keep an eye on the expiration date of your sunscreen. It can expire and will not provide the protection you think.

For a sensitive skin or sunscreen that isn't laden with heavy fragrance try Vanicream line of sunscreens. All three offer broad spectrum protection with a limited chemical footprint.

Aerosol sunscreens need to be banned because they infringe on my rights to breath fresh air. The warnings say to avoid inhalation and say further studies are needed by suncreen companies to provide evidence of safety...... NONSENSE!!!!! First do no harm Have you ever sat on the beach within 20 feet of a person spraying themselves?????? I am still trying to get the bad taste out of my mouth and throat and still snorting the particles out of my nose. Most likely they are there forever because those nano particles are meant to travel deeply into the skin. On the positive side.... I lost my appetite and may lose a few pounds.
