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.

Are you keeping track of UV Index? {Sunscreen}

[Source:thegolfforecast.com]

What's a UV Index? 

It's the measure of strength of sun's UV radiation. Its just like a weather forecast and tells you if you need to cover up from the sun or not. This measure has been standardised by the World Health Organisation (WHO) so its a reliable measure.

UV Index Table (Source)

How to check the UV index?

You can always google it for your own city. Another source is weatheronline.co.uk. I found it while doing the googling myself :D And, the UV index of Hyderabad for April 12 to April 15 is 12 (Source). Who would think with the weather out there (its cloudy and rainy these days) that the UV index and radiation would be so high??? So, Hyderabadis, apply proper amount of sunscreen and don't venture outside in the noon unless absolutely necessary!!!

PS: If you find the post useful, please don't forget to share it with your friends and family. Its a health issue which everyone should be aware of.

Summer Skin Care Essentials {Skin Care}

[Source:skinbeautyreview.com]

So, summers have started burning my skin here :( And, yes, I hate summers, a lot. I feel so hot and I don't really like AC's. I am more of a cooler gal!! Anyways, let us go through some summer skin care tips. And, I had meant to put up this post long long back but somehow laziness wore me down :S

• Sunscreen: Must, Must and Very Essential!!!
• Hats/Scarves/Umbrella (a light colored one): Accessories to protect yourself from direct sun rays. 
• Don't go out after 10 and before 5. Rays are very strong. 
• Tanning happens very easily in summers so protect your skin. 
• Drink, Drink and Drink a lot and by drink, I mean water and herbal teas and fruit juices. 
• Shades/Goggles: Get trendy with wrap-around shades which match your face. They not only add a style statement but also protect your delicate eye area from the sun rays and prevent fine lines and wrinkles.

Day - time Routine

• Cleansing: Don't over-cleanse your face in the heat. I know sometimes the face feels a lot itchy and prickly and the immediate impulse is to wash it off which you should when you have just come back from prolonged exposure to the sun. But, not if your skin just feels the heat. Cleansing the face twice to at most thrice a day is enough. And, get a cleanser which helps control oil.

• Toning: Very very important in summers as skin goes less on the hydration. Make sure you use face mists at regular intervals and apply it just before putting on the moisturiser to trap in the hydration.   

• Moisturiser: Heat is building up so you really don't want a moisturiser which makes you look like an oil pan. Go light and easy on your body lotions and face moisturiser. Go for the oily moisturisers unless your skin too dry. They help control oil and keep the face shine-free.

• Sunscreen: An absolute must and should not be ignored at any cost. Get a stand-alone sunscreen instead of moisturiser with spf claims. And, apply a good amount of sunscreen for adequate protection.

How much sunscreen do you apply? {Sunscreen}

I have read so many reviews on other blogs and sites especially on sunscreens. And, I have found out one terrible mistake which people make - amount of sunscreen to be applied for proper protection. Many people apply a drop of the product or equivalent. That got me thinking about the amount of sunscreen which should be applied for optimal protection. And, then, I came across a comment in facebook by Renne Rouleau which said that two finger length amount of sunscreen should be applied to every part of the body. 

So, I tried to find more about what is the ideal amount of sunscreen which should be applied. And, the information I came across was correct. If one applies amount of sunscreen which can be traced along the length of their middle finger, they get adequate protection of 45 minutes and if they apply the amount traced across both their index and middle finger, they get optimal protection of 2 hours and 15 minutes. And, this amount of sunscreen has to be applied to every part of the body. The body is divided into 11 parts - face and neck, upper back, lower back, chest, stomach and waist, both upper thighs and lower thighs including feet. So, you need to apply two finger length amount of sunscreen for every part of the body for optimal protection. And, sunscreen has to be applied every half hour according to the article I am referring to.

So, how much of this advice do I follow? Ok, no, I do not reapply any sunscreen after going into the sun. Not even during my vacation. And, I apply only a finger length amount to my face and neck. May be it is pretty less but frankly the products is so heavy and makes my skin so oily that there is no scope for reapplication unless I wash off my face and do the whole routine again which is again quite an impossible thing. But, how so ever much one might be diligent with sunscreen application and reapplication, it is always best to stay out of sun. I try to follow that rule most of the times :)
