Description
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. You can buy sun cream in pharmacies, supermarkets and discount stores, with some of our tested options coming from Asda, Boots, Garnier, Nivea and Wilko. 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.
The NHS recommends reapplying sun cream every two hours, as the sun can dry it off your skin. They add that when applying sun cream for the first time that day you should do this twice: 30 minutes before going out and again just before leaving. For any product to provide the SPF it claims, you need to apply 2mg per square cm – which means around a teaspoonful of product for your face. And, just as with sun cream, it needs to be reapplied regularly. Physical/mineral products reflect visible light as well as UV, which can make the formulations opaque and leave a white residue on the skin. Some formulations use nanoparticles of titanium dioxide and zinc oxide – the minerals responsible for the residue. Nanoparticles are smaller, and as they scatter visible light – rather than reflect it – the sun creams are transparent. How to use sun cream UV protection: Sun creams receive a UV star rating out of 5, which measures how well a sunscreen protects against the sun’s UVA rays. Broad-spectrum sun creams protect against both UVA and UVB rays. Babies less than six months old should be kept out of direct sunlight, according to the NHS, and the skin of young children should be protected from the sun when UV levels are high.

Dr Paul Banwell told us, "Some sunscreens use chemicals, such as oxybenzone, a known- allergen, and avobenzone to absorb UV rays, which can be detected in the body at harmful levels." Water resistance: For a sun cream to be water resistant, it must have undergone testing to show that it stays effective for at least 40 minutes in the water. After this time, you will need to reapply. Sun protection factor: SPF indicates how long it may take you to get burned after applying sun cream, and is measured in numbers. The higher the SPF number, the more time you may be able to spend in the sun without getting burned.
It's common for sun creams to claim to be 'water resistant', but this doesn't mean that they're waterproof. There’s a long list of ingredients that are used as chemical absorbers, so it’s easiest to simply look for products that are labelled ‘sensitive’ rather than search for specific ingredients. SPF make-up: does it really offer protection from the sun? I would avoidOctinoxate,which is harmful to coral reefs and can cause skin allergies as well asAvobenzone,which can cause high levels of irritation. You also need to avoid Retinyl Palmitate, which does not mix well with the sun. When mixed with the sun, it can be potentially cancerous."For more details on the importance of vitamin D and where to buy supplements, see our in-depth vitamin D guide . Other ways to stay safe in the sun 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: It takes longer for those with darker skin that rarely burns – it can take 25-40 minutes for the darkest skin type.
Dr Paul Banwell, who runs The Banwell Clinic and is the previous head and founder of The Melanoma and Skin Cancer Unit (MASCU) in East Grinstead, agrees. He told us: "I cannot emphasise enough the importance of selecting a broad spectrum sunscreen, which will protect against UVB and UVA rays. UVB rays cause redness and sunburn as well as skin cancer, while UVA rays can also cause cancer as well as ageing of the skin. Newer sunscreens have infrared (IR) protection too and should be considered." Sun creams to avoid: The warning signs to look out for We saw an average 74% decrease in SPF protection at the end of the tests. We shared our concerns with Cancer Research UK (CRUK) and the British Association of Dermatologists (BAD). Both advise against relying on any sun cream for extended periods in the sun.Consider the time of day – If you're spending time in the sun without wearing sun cream, you should only do so before 11am or after 3pm, as the middle of the day is when you're at the greatest risk of getting burnt. We tested two popular sun creams in chlorinated water (to mimic a swimming pool) and salty water (to emulate the sea). We also added another scenario using fast-moving tap water to see what effect this had. Most of the time, the products weren't as effective in our more realistic conditions as they were in tap water.
