Sunscreen effectsDo you use sunscreen? Not always? You not only should, you must. It’s very important that you do so whenever you go out. Why is that? Because if you don’t do so, you are running the risk of skin cancer.

It is vital that you more about how it works and how much you need. Let’s look at the facts shall we?

The sun’s light though essential for our existence, also contains some harmful rays. Essentially they are two kinds of UV rays. UVA ages your skin and UVB causes sunburns. You need to protect your skin from both kinds as they can cause skin cancer. This is all the more important when you are on the beach as you get a greater dose of UV.

How much should you use?

We are often told that it depends on the SPF (sun protection factor) of the particular brand. That is a fallacy. We would expect a SPF of 100 would be twice as effective as a SPF of 50. In fact it is only a few percentage points better. This may surprise you, but a SPF of 15 screens 93% of the rays while a SPF of 30 screens 97%. As you can see, beyond that the SPF becomes irrelevant.

So how much should you use? According to Mona Gohara, MD, a dermatologist in Danbury, Conn., and an assistant clinical professor at Yale University dermatology department, most people don’t use enough. She says that the for the most effective protection, use 1 to 2 ounces, about the size of a ping-pong ball, over the whole body, 30 minutes before leaving the house and every 2 hours thereafter as long as you are exposed to the sun. If you are not sure, it’s better to put on more than less.

She advises that a dollop the size of a silver dollar should be adequate to cover your face. It is a fact though, that most people while covering the face, tend to forget the scalp, ears and neck.

So what about the SPF Factor?

According to cosmetic dermatologist Dr. Dina Strachan, the American Academy of Dermatologists recommends a minimum of SPF 30 on both the face and body. Dr. Strachan says that a SPF factor of 15 ought to be enough, except that most people don’t use enough sunscreen in the first place.

Should we use sunscreen under our clothes?

An average T-shirt has an SPF factor of about 7, so yes you should use sunscreen under your clothes too. Clothes with a tight weave and /or darker color tends to keep out more UV, but why take the chance? You are less likely to wear such stuff in summer when the risk is higher.

The alternative is to wear UV protected clothes. These are made of fabric that are treated with a special UV absorbing dye that gives it a SPF factor of 50 or so. Although you may not want to invest in a new wardrobe right away.

Can sunscreen cause cancer?

sunscreen effects
No it can’t. The only way it could cause cancer is if it absorbed by your body and that does not happen. If you are still concerned use a sunscreen that contains zinc oxide or titanium. This form a physical barrier that stops the product being absorbed.

Do we need to reapply “water-resistant” sunscreen after swimming?

Yes. Water-resistant is not the same as water-proof. No sunscreen can be truly water-proof. You should apply sunscreen whenever you come out of the water, or have worked up a sweat.

So now you know all you need to know about sunscreen. Bear it in mind and use it to keep yourself safe from the sun’s rays
