Do layers of sunscreens help? {Skin Care}

· · 23 Comments

The first rule of applying sunscreen – The spf’s of various products don’t add up!!! If you are applying a moisturiser with spf, say x, then a sunscreen / foundation / BB cream with spf, say y, and then finish off with a mineral compact which again provides some spf, say z, factor, you can’t say that the sum total of your sun protection factor is spf x+y+z.
But, something else bothers me in this rule!!! Well, when we have layers of product with spf factors, x, y or z, which spf does apply on the skin – x, y or z? Or, does it work like a filtering mechanism? Meaning, if supposing the top layer has spf of z, those many rays are allowed to pass (remember even 50 spf allows 2% sun rays to pass through, it provides around 98% protection!!). And, then, the next product spf, which is y, again filters out the rays according to its strength and so on!!
Does that happen at all? Well. logically speaking, it does seem quite probable but I don’t know how much of that really applies in practice. Would be great if some sunscreen expert can answer such questions!!! What are your thoughts on it?

Are you keeping track of UV Index? {Sunscreen}

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.

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 😀 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.

How to remove tanning on arms? {Skin Care}

· · 9 Comments

Tanning on my arms has been a long standing issue. And, last week, when someone requested me remedies for the same, I thought I would better do a post. Disclaimer: I wouldn’t say that I am entirely rid of the tan but I have surely made some progress in the recent years and now, my hands looks a little better than what they did 5-6 years back. 
All of my issues started with the college whether hair or skin. In the school, everything was covered upto the neck and the arms were entirely shrouded in full sleeves and even my socks used to reach the knees and my skirt used to end just above so my knees were definitely one of the most hit parts of my body. But, since, I have been covering my legs ever since, my knees and the surrounding areas have lost all the tan and returned to their normal shade again.
But, now, the issue remains with my arms and neck. My face is still doing a lot better. So, how to save the arms?
  • Elbow-length Gloves: Yes, those which are used for driving. I had started to wear them pretty regularly a year or two back and had noticed my arms coloring had improved quite a lot. But, I shall also accept that they are uncomfortable and cumbersome but then, we do wear scarves all over the face, right???
  • Sunscreen: Oh yes, absolute must. Arms get tanned very easily and we generally tend to miss them out while applying the sunscreen. But, applying sunscreen on the arms do make a huge deal of difference. I have tried Biotique ones and have received great results and they are economical too. And, right now, I am using Neutrogena Ultra sheer which is equally good but definitely not so economical for me.
So, those were my two pennies on how I protect my arms and seriously, I have never done anything more for my arms or any other part of my body except face and probably neck (which shall be another post!!).
