Do We Really Need SPF50? We Got Experts to Weigh In
As the school holidays quickly approach and many of us will be jetting off to warmer climates and purchasing that all important sunscreen. As a beauty editor I'm an advocate for wearing SPF on my face everyday, but even I have to admit when it comes to the rest of my body I often forget, until I'm on holiday, either in the UK or abroad, and then I will ensure my body is covered in sunscreen from top to toe. And it seems I'm not alone, a survey by Face the Future, which launched its 366 Days of SPF campaign with a YouGov, found 40% of people the 20,000 people asked, only use SPF when abroad and 35% wear SPF30 or less.
In the past, when sunbathing was still a thing, I remember starting with a SPF 15 and then slowly lowering the factor as my tan developed believing my skin had become accustomed to the sun. Fast forward a decade and our awareness of wearing high factor SPF and the damage the sun can do in terms of skin cancer and ageing has increased 10-fold. Which is why I find these stats surprising. I would never go in the sun without a good layer of high factor sunscreen, with a minimum of SPF 30 at all times or let my children wear anything less than SPF50 — but according to the research 14% of people still do not wear any sunscreen at all and only 8% of people reapply their sunscreen throughout the day.
There has also been a recent furore online with comments and videos discussing why we shouldn't be using high factor sunscreen at all or and that SPF 30 is in fact better for your skin than SPF50. With all this information and nearly 40% of people still not worried about the damage the sun can cause, it seems we still haven't got our heads around the importance of SPF to help fight cancer, ageing and skin damage.
I decided to speak to a leading dermatologist and skin experts who could explain the truth about SPF and why you really need to stay protected in the sun. I'll also recommend some of my favourite tried and tested SPFs, depending on your needs.

What Is the Difference Between SPF50 and SPF30?
"It is widely recommended that we should use an SPF of at least 50. But in actual fact, the difference between the level of protection that each offer is similar," explains Dr Hall. "SPF 50 provides approximately 98% protection from UVB rays whilst SPF 30 provides approximately 97% protection. This rises to 99% protection for SPF 100 but it is important to note that no SPF can provide 100% protection."
So does this mean we should all be ditching our SPF50 and moving to SPF30? "Whilst the percentage may seem small and insignificant it does become important if you are spending prolonged periods in the sun or have specific skin conditions such as actinic keratosis," Hall explains, "and the higher the SPF the better."
It is also worth noting that the SPF needs to target both UVA and UVB rays, this is usually worded as broad spectrum on the bottle. "When selecting suncream, it's crucial to ensure it provides broad-spectrum protection," explains Kimberley Medd, clinical lead at Face the Future. "This means it protects against both UVA and UVB radiation. The Sun Protection Factor (SPF) measures how well the suncream protects against UVB rays." This means the superficial damage the sun can cause such as burning, where as UVA rays penetrate deeper and can cause long term skin damage, ageing or cancer.
What Should We Consider When Buying SPF
There are a couple of things to consider here in terms of what you want the SPF to do and where you are wearing the SPF. However, I believe you are far more likely to wear a product if you like how it feels and looks on your skin. "Personally, I'd look for hydration - ingredients like glycerin, vitamin E," says Ava Chandler-Matthews, founder of Ultra Violette. "Antioxidants like vitamin C, E, green tea are always beneficial too."
If you have any inflammatory skin issues like acne or rosacea, then you may need to consider other factors too — especially for your face. "I would look for a zinc oxide-based SPF as the inclusion of zinc is a wonderful anti-inflammatory, " explains Chandler-Matthews. "It really depends on their skin type and concern but seeking out the highest SPF number, primary sunscreen (that is a product sold primarily as a SPF - and not a moisturiser or foundation with SPF) should be where you start," she tells PS UK.
Common SPF Myths: Debunked
"Not applying enough!" Chandler-Matthews tells PS UK. "Most people do not wear the correct amount of SPF. It's a 1/4 teaspoon for face." And when it comes to your body you should be looking at 1-2 shot glasses filled with sunscreen.
If you've been relying on the SPF in moisturiser or foundation to work for your face then think again. "This is a biggie and it's more common than you'd think," says Chandler-Matthews. "It doesn't count in makeup alone, even if it's a foundation with SPF 50+, you'd need to apply so much to get adequate coverage — hello mask face!"
One of the biggest misconceptions is how often you should reapply, it should be every two to three hours and every time you have been in the water or been heavily sweating. The other is, don't just apply on holiday. "You do need to wear it every day," Chandler-Matthews tells PS UK, even if you are indoors. "UVA rays penetrate through windows so reach you inside an office or in your car too."

Best SPF For Sensitive Skin
La Roche Posay Anthelios Ultra Light Body Mist SPF50 (£20)
I'm a big fan of this entire range, however I love this invisible spray formula that doesn't need to be rubbed into skin and is ideal for reaching all the awkward places like the back of knees and shoulders if you don't have anyone else nearby. I also find if I use this all holiday, it stops me from getting prickly heat.

Suitable for even the youngest of bubbas, this sunscreen has been formulated to be gentle enough to use on even eczema-prone skin. It is fragrance-free and lightweight so it won't feel sticky on the skin — ideal if you have a child who doesn't like the feeling of a heavy cream.

Soltan Active Mini Spray SPF50 (£6)
If you intend to spend your summer bike riding through the countryside or hiking up various mountains then this is for you. It is designed to be sweat and water resistant and also comes in this handy spray you can pop in your pocket and reapply on the go. Soltan is one of my other go-to brands as I feel its range has been sufficiently tested and offers both UVA and UVB protection.

Hawaiian Tropic Hydrating Protection SPF30 (£7)
To me this just smells like holiday. I used to love smothering myself with Hawaiian Tropics when I would spend hours sitting in the sun, but then avoided the brand as I moved to higher factors. It has now stopped offering the low SPF factors and concentrating on providing excellent protection from the sun with all the goodness — like the scent — of holidays gone by.

Rituals The Rituals Of Karma Sun Sunscreen Milky Sprah SPF50 (£20)
If you like the idea of a spray but hate the invisible formulas as you worry you will miss a spot then this is for you. Not only is the scent divine, it feels like less of a chore and more of a treat to use. The milky lotion quickly absorbs into the skin and doesn't leave a white cast but settles for long enough to see if you've missed any areas.

Best Budget Sunscreen
Piuz buin Allergy Sun Sensitive Skin Lotion SPF30 (£8)
If you have sensitive skin, which is prone to prickly heat, and don't have the budget for some of the more expensive brands it is worth giving this ago. It can be a bit too fragranced for some people to use on the face, but in terms of a good body option for under £10, this is up there.

Best Hydrating SPF
Ultra Violette Extreme Screen SPF50 (£27)
This gives skin such a gorgeous glow you will want to use it every single day. It is packed full of hydrating ingredients so it won't dry skin out even if you're sitting on a beach or pool all day long. It lasts up to four hours in water which is great, if like me, you like to sit in the pool and cool down.
