Everything You Need To Know About Sun Protection

The Sun: the source of all the energy on Earth, crucial to every part of our being. But with the depletion of the protective ozone layer, the UV rays emitted from the Sun have more of a detrimental effect on our bodies. So we need to up our own protection of our skin, and this is why it is so important to pick the right sunscreen. Creating our sunscreen, Revitalising High Protection Fluid SPF30, was a challenging process because we could not find a single sunscreen that ticked all the boxes we needed from one – so we made our own! Its fluid texture ensures you can reapply it as often as you like without clogging your pores or compromising on broad spectrum chemical and physical sun protection.

A good sunscreen isn’t just about looking at an SPF number on a bottle – it’s a whole lot more than that and I’m here to provide my expert tips on how you should be protecting your skin against the sun and why.


Why is too much sun exposure bad for you? 

Too little sun exposure is also bad for you as you risk becoming deficient in Vitamin D, which is needed for healthier bones and a better immune system. But too much sun exposure can increase the risk of cancer, and scientific studies have shown that up to 90% of the visible signs of ageing are a result of UV exposure.

There are 3 types of UV emissions from the sun: UVA, UVB and UVC. The ozone layer still protects us from UVC, whilst UVB affects the skin epidermis causing sunburn and UVA penetrates the skin’s epidermis to induce the production of free radicals and this is havoc at a much deeper level and compromises the size of the dermis layer by damaging the collagen and elastin that hold this layer together. Over time, the epidermis then hangs over this smaller layer, resulting in a wrinkled or lined effect on the skin.


Wear the best sunscreen: how to choose your SPF

You’ve gathered by now that a good sunscreen will provide broad spectrum protection against both UVA and UVB rays. The SPF (Sun Protection Factor) rating given to sunscreens, like the SPF30 in our Revitalising Fluid, indicate the level of protection against UVB rays and provides 30 times the protection versus no sunscreen. This is not meant to say SPF50 is better – in fact I recommend SPF30. Why? Because you have to reapply your sunscreen every 2-3 hours anyway (people sweat, your skin produces oils, you swim etc. – in other words the protection disappears). So SPF50 won’t protect you better than SPF30. Reapplying sunscreen is the most important tip of all, rarely do people reapply when they should and that is when photoageing will occur.

But what about UVA protection? After all, this is the one we should be slightly more worried about as it penetrates deeper into our bodies. Unfortunately, this is where a lot of US-manufactured sunscreens just don’t stand up to or work as well as European-manufactured ones like our Revitalising Fluid. This is because under EU regulation, sunscreens must contain at least one third as potent a UVA protection as the UVB protection: i.e. a sunscreen of SPF30 must have a UVA protection of at least 10.

Furthermore, look for whether your sunscreen provides physical protection which sit on the skin and reflect rays(in the form of Zinc Oxide or Titanium Dioxide in the formulation) or chemical protection that sit within the skin and absorb the UV rays. The best needs to be a combination of both physical and chemical protection. Our Revitalising Fluid is one of the few that has physical UVB protection in the form of Titanium Dioxide, and the very latest and best chemical UVA blocking protection which does not interfere with other parts of the body processes and sits within the skin to neutralise the effect of UVA rays. Unfortunately, there are many sunscreens out there that just do not have this protection. Check your product’s ingredient listing.


Always choose quality

Before I launched Elethea, I was using other sunscreen products and thinking it was OK. Knowing what I know today, I am happy to share it with you because I believe looking after our skin with quality ingredients is like eating good, clean and wholesome foods – over time you will reap the benefits, even though you may not see a short-term benefit. We are here to provide knowledge and to encourage you to choose quality in your skincare products, including your sunscreen. Make sure your sunscreen is the best you can get and I can assure you that your skin will age healthily and not prematurely. Also ensure that you have great antioxidants and oils (like the unique Pumpkin Seed Oil in our Revitalising High Protection Fluid) in the product.

    This is really informative – I never knew you had to look for both UVA and UVB protection, I just thought the number on the SPF was enough. I would really like to try your SPF product – is it suitable for all skin types?
