Most people know that wearing sunscreen is an essential part of summer. I particularly don't like to get sunburnt, nor do most people I know. It is common for sunscreen to be forgotten about through the milder months - however, it is a misconception that sun protection is only required when it is hot, or when you are outside. Read on to see why we should be wearing sunscreen year-round.

The sun emits three types of UV radiation: UVA, UVB and UVC. They are emitted from the sun all day, every day. The UVA and UVB are the rays that cause significant damage to our skin if we do not protect ourselves when we are outdoors. (UVC rays are the most damaging however they do not reach the earth's surface).

UVA

UVA is a radiation that penetrates deepest into our skin. It is the radiation that causes us to tan, destroys the skin's elasticity, and rapidly ages and wrinkles the skin. It also contributes to the development of skin cancers. This type of radiation can penetrate glass so unless your office or car window's are treated to filter UVA, it is still important to protect yourself whilst indoors or travelling.

UVB

UVB is the main cause of our skin burning, visible changes to the skin, and the development of skin cancers. The strength of these rays vary depending on the time of year, location, time of day and season. However, UVB can still have an effect on your skin all times of the year.

You might be interested to know that UVB rays (as well as UVA) are reflected from sand, water and snow which is why so many people burn so badly whilst swimming and even skiing (even when wearing a hat!).

What Should I Look For in a Sunscreen?

Most people buy their sunscreens based on "SPF" rating. The SPF rating is only related to protection against UVB rays. (Regardless of the SPF rating you should generally apply sunscreen 15-20 minutes before sun exposure and be reapplying every two hours for sunscreen to have proper effect.) Before really looking into the importance of sunscreen I had no idea what the difference between the SPF ratings were:

• 15 SPF filters approximately 93% of UVB rays

• 30 SPF filters approximately 97% of UVB rays and,

• 50 SPF filters approximately 98% of UVB rays

As you can see, there isn't a staggering difference between them! I also had no idea that you needed to find a sunscreen that protects you from both UVA and UVB rays. "Broad spectrum" is something you should look for when purchasing your next sunscreen - this means the product has been tested and proven to protect against both UVB and UVA light. 

There are so many sunscreen options to choose from, I would always find it overwhelming knowing which one to purchase. I now know that buying a broad spectrum sunscreen with a 30 or 50 SPF rating, following instructions of application and applying year-round would be the best bet to keep your skin in check against UVA and UVB rays. (Also don't forget about your lips, there are many great options for sun-smart lip balms out there!)

What About My Hair?

The sun's harmful rays are also bad news for your hair; if you don't already wear a broad brimmed hat to protect your scalp and hair, it is a good idea to do so. Repeated exposure to the sun can cause the natural oils from your scalp to evaporate, leaving your scalp and hair dry and dull. Sun exposure damages the protein bonds in the hair - healthy protein bonds ensure your hair is strong, flexible, shiny and free from frizz. Lastly, it also affects your hair colour (whether your hair is virgin or chemically coloured). Too much time in the sun will strip the colour pigment from the hair shaft over time; this is why some people find their hair lightens naturally during the warmer months.

There are many hair products on the market which protect against UVA and UVB rays, perhaps consider picking one up next time you're in salon to protect your fresh colour!

I recently picked up a face sunscreen from MECCA as I have never purchased a sunscreen specifically for my face. The texture is super silky and not at all drying or greasy which was a lovely surprise. I also give my hair a quick spritz all over with the Mr. Smith Texture Spray which has UV protection. It takes literally an extra 30 seconds of my morning to pop some SPF on so there is really no excuse!

What sunscreens have you been loving at the moment? I’d love to hear some recommendations - let me know!
