Product Information

A spokesperson added: 'As with all sunscreens, it is important to follow the instructions for application and use; and sunscreen should not be used to intentionally stay longer in the sun. Sunscreen is just one part of a sun safe regime.' Boots This is because, she said, the length of protection can vary depending on a person's activities - including how much they sweat and whether they towel dry, for example. Professor Brian Diffey adds that sun creams generally offer ‘very good’ water resistance these days (though be aware water resistance claims also come with caveats, and the products we tested didn't hold up well to real-life conditions in our 2016 investigation), which is good if you're planning on spending time in the pool or in the sea. But over the course of the day swimming will wash away some of the protection. It’s no wonder that doctors, dermatologists and beauty editors alike will tell you that protecting your skin is of paramount importance. But sadly, not all sunscreens are created equal. As is often the case, it’s worth investing in a quality product that will do the job effectively and give you much-needed peace of mind whether you’re at the beach, park or just lounging in your garden.

The sun emits two types of ultraviolet radiation. UVA affects the skin’s elastin, leading to wrinkles and premature ageing (although it’s also linked to developing skin cancers). UVB is responsible for sunburn and can increase the risk of skin cancers, too. Certain sunscreens carry a UVA star rating from zero to five, which indicates how much UVA radiation they absorb, relative to UVB radiation. Don’t be alarmed if there isn’t a number on the bottle, though: the rating system was devised and is owned by Boots, so not all brands carry it. Remember, sun cream is just one part of staying safe in the sun and it's also really important to encourage kids (and adults) to: A spokesperson told us that all of its sun creams are designed for 'longevity' but that it found the use of the word 'durable' more 'appropriate' than once a day.When choosing sun cream for your child, look for a short ingredients list and the terms 'fragrance free' and 'hypoallergenic'. The WHO recommends 35ml of sun cream (seven teaspoons' worth) to cover an adult, so use around a quarter to a half of this depending on the size of your child. They were allowed to wear t-shirts and sit on a chair (we did this because if you lie on a sun lounger or towel, get sandy, or wear a t-shirt on holiday it’s possible your single-use sunscreen could be rubbed off over time).

Professor Brian Diffey, of BAD, says: 'We recommend against relying on any sunscreen product for long periods without reapplication, whether advertised as an extended wear product, or not. My advice would be to find a sunscreen that you enjoy wearing, that doesn’t interfere with your joy of running, and build it into your ritual the same way you do with fuelling and stretching,' says Austen. Sun cream provides protection from sunlight using UV filters. These are classified into two types: chemical and physical – also known as mineral sun cream. The industry guideline for water-resistant sun creams allows the SPF of a product to drop by 50% after a total of 40 minutes in water. Water-resistance testing also takes place in what is essentially a bath – using tap water. Yes, you can - but you’ll also need to reapply frequently, just like you would if you were on the beach staying dry, and immediately after towel drying.

Bear in mind that running at altitude means you’ll be more exposed to UV rays – up to 10% more for every 300 metres above sea level,’ he adds. ‘Nobody ever regretted wearing sunscreen, but we have all regretted skipping it… Skin damage is long-lasting, difficult (if not impossible) to reverse and yet massively avoidable.’ How often should you apply facial sunscreen? Cover up – wear sunglasses to protect your eyes and grab a hat if you need to keep your face out of the sun. You might also want to wear a T-shirt, which can help to cover up typically over-exposed areas such as shoulders. We made multiple attempts to get in touch with Calypso, but the brand did not respond to any of our questions or send us a comment. Riemann

UVA rays might not cause you to burn, but they do penetrate more deeply into the skin and play a greater role in premature skin ageing. The British Association of Dermatologists suggests that an SPF of 30 and a star rating of four out of five is “generally considered as a good standard of sun protection” (as long as this is paired with protective clothing and periods spent in the shade). The EU recommendation is that creams should offer UVA protection that’s at least a third of the SPF, so if you see a bottle with the letters UVA in a circle, you can be assured that it meets this minimum requirement. Sunscreens that offer strong protection against both UVB and UVA radiation are termed “broad spectrum” products.It's clear that there are plenty of conditions to fulfil to get the claimed protection from once-a-day products, which may be hard to achieve if you're on a day out in the sun. Don't just rely on sunscreen either: use clothing, hats, sunglasses to cover up, and seek shade, particularly when the sun is strongest, between 11am and 3pm - regardless of whether you are wearing sun cream. According to the Met Office, even when the weather is overcast, UV radiation can still be 80% of its normal levels. Not to mention, the temperature can be deceiving – especially if there’s a breeze making it feel a lot cooler than it is. So even if it's cloudy it's important to protect yourself. Nobody applies sunscreen perfectly uniformly to all exposed skin and it is inevitable that we will miss patches of skin. It's common for sun creams to claim to be 'water resistant', but this doesn't mean that they're waterproof.
