Do you Really Need Sunscreen Every Day?

The short of it is yes.

But to be honest, – the long story is that sunscreen isnt just for beach days or summer holidays. Its a daily essential. Most dermatologists agree that protecting your skin from the suns UV rays is important all year round, whether its summer or winter, sunny or cloudy.

The sun spews out two kinds of nasty rays. UV B rays cause sunburns and basically rip apart your DNA which can lead to mutations and skin cancer. UV A rays slip deeper into the skin and contribute to wrinkles, an uneven skin tone and also skin cancer.

Lots of people think sunscreen is only needed on hot, sunny days. Which is a pretty common mistake. Up to 80% of UV rays can still get through the clouds, so you can still do some damage on overcast days . Snow, sand and water can all bounce sunlight, increasing your exposure. And UVA rays can even get through glass – so your skin is still at risk while driving or sitting near windows.

The Australian government’s SunSmart program and the Skin Cancer Foundation both reckon you should slap on some sunscreen whenever UV levels are 3 or higher. Which, for most places, is during most of the year, not just summer.

Why is Sunscreen Important For Skin Health?

Sunscreen is more than just a cosmetic thing. Its a health essential. Here are a few reasons why.

Prevents Skin Cancer

Skin cancer is the most common type of cancer in the US . UV radiation is a leading cause of it. A big trial in Australia found that using sunscreen every day cut the incidence of melanoma by 50% . Other studies have shown that regular use can cut the risk of squamous cell carcinoma, basal cell carcinomas and keratinocyte carcinomas.

The Australian trial looked at more than 1600 people at high risk of melanoma over ten years. In the group that used sunscreen every day, there were only 3 new cases of invasive melanoma. In the group that used sunscreen at their own discretion, there were eleven new invasive melanomas. The figures are pretty clear.

Prevents Premature Aging

Many people are eager to have skin that looks better – and it turns out UV light has a pretty big role to play in making your skin look prematurely aged . Sunscreen – the good stuff – can help shield against fine lines wrinkles and sunspots that come from getting too much sun over time . This whole process is called photoaging, and the good news is that with daily sunscreen use it can be prevented.

Maintains Even Skin Tone – And That’s A Good Thing

Problem is, sun exposure tends to make hyperpigmentation, melasma, and dark spots a whole lot worse . Daily sunscreen helps out in a big way by keeping those issues in check, which in turn helps to maintain an even skin tone . If you forget to put on sunscreen you tend to end up with sun spots in your skin, because UV rays basically get the melanin to work overtime – and in the end that just ends up looking like this weird darker patch where it shouldn’t be .

For The Health of Your Skin

Sunscreen does a whole lot more than just keep you looking good – it also helps protect your skin’s natural barrier and keeps the inflammation caused by UV exposure at bay . The thing is, if you get exposed to UV light over and over it starts to weaken the skin’s first line of defense, and before you know it you’re left with sensitive skin, dryness, and a host of other issues that are plain uncomfortable.

HOW SUNSCREEN ACTUALLY WORKS TO PROTECT YOU

Sunscreen does its thing by filtering out all those nasty UV rays before they can do any damage to your skin cells.

There are two main categories of sunscreen ingredients that you need to know about :

Chemical filters work by absorbing UV rays and then neutralizing them. Some examples are avobenzone and octocrylene, and the good news is that they offer pretty broad UVA and UVB coverage. They can however sometimes cause irritation.

Mineral filters on the other hand work by deflecting UV rays away from your skin . They sit on the surface of the skin which means they are pretty unlikely to irritate it. Zinc oxide and titanium dioxide are two examples . Both types of ingredients can be effective, but they do require one crucial thing : broad-spectrum protection. Choosing mineral sunscreens may be best if you have sensitive skin, while chemical sunscreens are probably the easier of the two to apply evenly

The problem is, sunscreen only works if it is applied correctly . That is where most of us are screwing it up.

What Happens When You Forget To Wear Sunscreen

Not wearing sunscreen might seem like it’s no big deal for just a short walk, but if you do it a lot the cumulative effects of all that sun damage really do start to add up . Here is what can go wrong :

Sunburn – Just The Worst

This is the most immediate and obvious damage sun exposure can do. UVB rays basically just cause a huge amount of direct DNA damage and that in turn gives you that tell-tale redness and burn . Severe sunburn is no joke – it can make you feel like you have the flu, dehydrate you, and even make you feel loopy

Your Skin Starts to Fall Apart

Not wearing sunscreen also does a number on your skin’s collagen and connective tissue – and that is what leads to a whole lot of wrinkles . Over time the visible signs of premature aging start to pile up : pigmentation, visible veins, broken blood vessels, brown spots, fine lines, and of course wrinkles.

It Makes Your Skin Tone Go Haywire

When you expose yourself too much to the sun’s ultraviolet (UV) light, your skin becomes prone to producing more melanin than required. Melanin is a pigment which determines the color of your skin. In cases where there is excessive production of melanin, it leads to hyper-pigmentation whereby dark spots develop on your skin. These dark spots become visible and hard to get rid of with time when exposed to ultraviolet rays.

Skin Cancer Risk Goes Up

Repeated and frequent instances of sunburn can greatly enhance the risk of contracting skin cancer in the future. The ultraviolet rays of the sun cause harm to the DNA of the cells of the skin. This damage can gradually build up, resulting in abnormal cell growth and eventually causing skin cancer. Skin cancer has been recognized as one of the most common types of cancers around the world today.

Weakened Immune System

Overexposure to ultraviolet (UV) radiation is not only bad for the skin’s outer layers but can actually have an effect on your skin’s ability to fight diseases. The rays from the sun may actually reduce your skin’s immune capability, thereby reducing its ability to fight infections and repair damage to the body’s cells. Consequently, this makes your skin more susceptible to damage.

HOW TO CHOOSE THE RIGHT SUNSCREEN

Choosing the right Sunscreen – Made Easy

Here are the key things you need to know to pick the right sunscreen.

Broad-Spectrum Protection – Don’t Forget These Two Letters

When shopping for sunscreen, look for the label that says broad-spectrum. This is what the FDA calls a product that protects against both UVA and UVB rays – A for ageing and B for burning. You need both, trust me.

SPF Rating – What Number Do You Need?

Dermatologists suggest opting for a daily SPF of 30 or higher. Don’t worry too much about the exact number but think of it like this: SPF 30 blocks 97% of UVB radiation while SPF 50 blocks a bit more at 98%. For people who spend a lot of time outdoors, SPF 60 or above might be worth considering as people don’t always use as much sunscreen as they should.

Water Resistance – For Swimmers and Sweat-Prone Folk

If you swim or tend to sweat a lot, a water-resistant sunscreen is a must. Honestly no sunscreen is ever completely “waterproof” but water resistance does make it stick around a bit longer.

Mineral or Chemical – What’s best for Sensitive Skin?

If you have sensitive skin you might find mineral sunscreens (with zinc oxide or titanium dioxide) are easier on your skin . If on the other hand, you’re worried about chemicals being absorbed into your skin, mineral sunscreens are a safer bet.

SPF & PA Rating – What They Really Mean

SPF stands for Sun Protection Factor – a measure of how well a sunscreen protects you from those nasty UVB rays. Theoretically, it’s supposed to tell you how much longer you can stay in the sun without burning, compared to someone without sunscreen. eg, an SPF 30 product would protect you for a lot longer than just 30 minutes.

But here’s the catch, SPF ratings aren’t exactly linear, so SPF 15 doesn’t offer the same level of protection as SPF 30, which in turn doesn’t offer the same level as SPF 50.

PA rating is the measure of UVA protection. Think of it like a protection grade of UVA – more plus signs mean higher protection. In reality it’s not that complicated – just look for a product that protects against both.

• PA+ = 2-4
• PA++ = 4-8
• PA+++ = 8-16
• PA++++ = 16 or higher
