Hello Friends !

In the previous article, I told you about how to check whether your sunscreen is safe or not. Today, in this post, I am telling you about Sunscreen and Sunblock. 

Many people get confused about the difference between sunscreen & sunblock. They want to protect themselves from harmful sun rays and this is the reason that they switch to sunscreens or sunblocks. Many of you thought and ask often that which one is better ? Sunscreen or Sunblock ? There are many questions in your mind about two. Some people think "Are they same?"

Today, I thought to give you here some info. that will help you somehow. So, let's begin now.....

   SUNSCREEN  OR SUNBLOCK  

Sunblocks & Sunscreens can be equally effective.  They are made up of different ingredients. Sunblock contains titanium dioxide and zinc oxide, which create a reflective, mirror-like shield that helps to deflect the suns damaging rays from your skin. Sunscreen contains PABA, benzophenones, cinnamates and walicylates which work more like a sponge in that they soak up or absorb sun's harmful rays.

It is important to use a sunscreen that blocks both UVA and UVB rays. 

UVA rays are always present, no matter the weather or season and we're once thought of as less damaging. However, we now know that these rays are very powerful and are one of the main causes of premature aging, sun spots and leathery skin. UVA rays deeply penetrate the skin and can also penetrate clothing and glass.

USB rays are not strong as UVA rays, but they are the main cause of sunburns and skin cancer and thus are just as damaging, if not more damaging, than UVB rays.

To properly protect yourself against the sunburns and harmful rays, you must wear sunscreen or sunblock that contains SPF. SPF or sunprotection factor, is the measure of a product's ability to screen or block the sun's harmful rays.  However, figuring out which SPF you should wear can be very confusing,  especially with SPF numbers ranging from 2 to 100.

It would be natural to assume that SPF 100 would be twice as effective as a SPF 50. However, this is not necessarily true. According to the American Melanoma Foundation, " 😮If you use a sunscreen with a SPF 15, you can be in the sun 15 times longer than you can without sunscreen before burning. However, consumers need to be aware that SPF protection does not increase proportionally with an increased SPF number. While a SPF of 2 will absorb 50% of ultraviolet radiation, and SPF of 15 absorbs 93% and SPF of 34 absorbs 97%."

Sunscreens and blocks that claim to be completely waterproof or sweatproof just add to the confusion of SPF numbers. However, the one thing that typically holds true for all sunscreens and blocks is that it's important to apply 30 minutes before going in the sun and to reapply every two hours.

Because of this SPF confusion, the FDA is mandating some changes regarding the labelling of all skin protection products. These changes were originally going to take effect on June 18, but an extension has been issued to December 17, 2012. This extension was given by the FDA to give manufacturers six more months to comply with their new regulations so that we don't see a shortage of sunscreen and sunblock products, especially over the summer months.

To help minimize the confusion, the FDA is mandating the following changes:

● Sunscreen products that are board spectrum with SPF values from 2 to 14 will be labelled with a warning that reads : " Skin cancer/ Skin Aging Alert: Spending time in the sun increases your risk of skin cancer and early skin aging. This product had been shown only to help prevent sunburn, not skin cancer or early skin aging."

● Water resistance claims on the product's front label must tell how much time time a user can expect to get the declared SPF level of protection while swimming or sweating, based on standard testing. Two times will be permitted on labels: 40 minutes or 80 minutes.

● Manufacturers cannot make claims that sunscreens are "waterproof" or "sweatproof" or identify their products as sunblocks. Also, sunscreenso cannot claim protection immediately an application  (for example, "instant protection") or protection for more than two hours without  reapplication, unless they submit data and get approval from the FDA.

● Any sunscreen with a SPF higher than 50 will have to be labeled SPF 50+
