is SPF 70 TOO HARSH??

Answer 1

Not unless you want skin cancer.

Assuming it really is 70 SPF, meaning that it would allow you to spend 70 times as much time in the sun as if you didn't have any sunblock on, I don't see the problem.

Unless it costs way more than SPF 40 or 50, in which case, just buy the SPF 40 and remember to reapply, reapply, reapply, .....

Even with a good sunblock, and plenty of reapplying it, though, there will come a time when you've had too much sun and should seriously think about finding some shade or going back indoors. There is no absolute protection against sun damage.

[EDIT] Beware of RussianCatSima's wildly misinformed assertion that sunblock actually causes cancer. There is absolutely no reputable evidence to suggest that sunblock or sunscreen causes cancer. That is a BS myth that's been floating around the Internet, and is being pushed by (among others) Kevin Trudeau.

Here's what the March 2006 issue of Scientific American had to say about Trudeau:

"Up to 139 times in one week, Kevin Trudeau pitches late-night viewers about his self-published book, Natural Cures "They" Don't Want You to Know About, a rambling farrago of uninformed opinions, conspiracy theories and cheeky jabs at medical, pharmaceutical and governmental authorities ("they"). The book is so risibly ridiculous that even the most desperately ill would not take it seriously--would they?"

Later in the article....

"So Trudeau is free to dole out in print such opinions as these: "Medical science has absolutely, 100 percent, failed in the curing and prevention of illness, sickness, and disease." (Smallpox is not a disease?) "Get all metal out of your dental work." (Won't this help the medical cartel?) "Sun block has been shown to cause cancer." (References?) "Don't drink tap water." (Wrong: studies show it is as safe as bottled water.) "Animals in the wild virtually never get sick." (No need to worry about avian influenza.) "Get 15 colonics in 30 days." (Can I bring a friend?) "Wear white.... The closer you get to white, the more positive energy you bring into your energetic field." (Why is Trudeau wearing all black on the book cover?) "Stop taking nonprescription and prescription drugs." (Including insulin for diabetes?) "This includes vaccines." (Welcome back, polio.) "Have sex." (Without prescription Viagra?)"

Don't take the word of whack-jobs like Trudeau. If you're concerned that sunblock might cause cancer, seek out some hard science on the matter. A reputable study, done by reputable scientists, with plenty of data to back up it's conclusions, would be a good start. Barring that, don't just believe whatever some wacko on the Internet tells you (myself included).

Seriously, it is *very* well established that too much exposure to the sun is one of the leading causes of cancer worldwide. In other words, we KNOW, without a doubt, that overexposure to the sun causes cancer. On the other hand, when it comes to sunblock causing cancer (allegedly), *all* we have to go on is the word of a bunch of alarmists and conspiracy theorists like Kevin Trudeau and others, who run for the hills when you ask them to point to any shred of data to back up their assertions.

Of course, RussianCatSima is right about one thing: there is a third option. Stay out of the sun as much as possible..

Answer 2

Use no less than an SPF of 15. Since it is just 20-35*C then you definately usually want not more than 35 (if you happen to burn without problems). Non-Chemical sunscreens are secure to make use of beneath the attention, nonetheless, don't practice them immediately, directly from the tube to the attention subject. Rub your arms in combination and lightly pat it in to the subject. Though you'll purchase eye lotions that include SPF. :)

Answer 3

I read a lot of publications, that sunscreen actually causes cancer, due to chemicals they contain.
I personally never use any skin products containing it...
Just stay in the shade, whenever possible....
