Sunscreen and Myths {Skin Care}

[Source:healthmeup.com]

One of the reasons why I am doing many posts on sunscreen again is to raise the awareness that it is an important part of skin care routine. Today, I shall be talking about some of the myths concerning sunscreens. Hope this helps clear some of your doubts.

Myth: Sunblocks are better than Sunscreens

There is no such thing as sunblock and I have mentioned this in one of earlier posts too. Earlier, physical sunscreens (which include Zinc Oxide or Titanium Dioxide) were called sunblocks as they scatter or reflect the sun's rays when they fall int he skin as opposed to being absorbed and converted into heat energy which happens in case of using chemical sunscreens. 

But, now, FDA (Food and Drug Administration), US has passed out certain rules regarding the labelling of sunscreens in which it has banned the use of certain terms "sweat-proof, water-proof, sunblock, dermatologist tested" as they are misleading. I know these rules are not applicable on Indian products but it at least shows that these terms do not really mean anything. 

Even the labels of spf 70, spf 90, spf 100 have been banned. If a sunscreen provides higher protection, it should be labelled as spf 50+. You can see Neutrogena following these labelling standards to get an idea.  

""Waterproof," "sweatproof" or "sunblock" claims. Manufacturers cannot label sunscreens as "waterproof" or "sweatproof," or identify their products as "sunblocks," because these claims overstate their effectiveness. Sunscreens also cannot claim to provide sun protection for more than 2 hours without reapplication or to provide protection immediately after application (for example-- "instant protection") without submitting data to support these claims and obtaining FDA approval.

Myth: SPF 100 gives me better protection than SPF 50

Spf 15 filters out 93% sun's rays, spf 30 filters out 96.4% sun's rays and spf 50 filters out 97.6% (near abouts). And, any spf higher than 50 gives only a marginal increase but there is no sunscreen which can filter out 100% sun's rays. For Indian climate, spf 30 is enough but if you are over-inclined, spf 50 is good. Anything higher is a false claim.

Myth: Layering of products with sunscreen will give me enough protection

I have talked of this issue earlier that spf's of various products do not add up!!! They all act as a single layer of sunscreen and provide the protection of the highest spf factor.

Myth: I don't need a sunscreen when indoors
UVA rays can penetrate through windows and glass. Read this post for more information about them. So, you need at least an spf 15 when staying indoors.

Myth: A drop of my new sunscreen keeps my face protected.
As a rule, you should apply one teaspoon or two fingers length of sunscreen to your face and neck. And, I know that's a lot. But, if you do not apply the said amount, the efficacy of your sunscreen is reduced according to the amount applied. So, even if you are using a spf 50 sunscreen, improper application might be giving you benefits of only spf 10 or 20. So, apply proper amount of sunscreen to protect yourself well.

These are some of the myths I have come across in my course of blogging, the top most being the confusion between sunscreen and sunblock. I hope this post helps to debunk those myths.
