This means that many chemical sunscreens deliver an impressive user experience, leaving no chalky texture or white cast behind. Think of them as a bat, hitting them away before they can enter the skin."Ĭhemical sun filters, such as the commonly used oxybenzone and octinoxate, are absorbed by the skin. Mineral filters, often referred to as ‘physical filters’, deflect the rays.

Think of these filters as little sponges that collect the rays, stopping them from entering your skin and damaging it. These two types of filter work in different ways to shield the skin from UV rays, as Dr. Sun creams generally fall into one of two categories: mineral and chemical. Even sunscreens that say they only need to be applied once a day should be re-applied after swimming." Mineral vs chemical sun cream "It is always recommended that to maintain maximum protection, sun cream is re-applied after swimming. "No sun cream is 100 per cent waterproof and some will get washed away when you are in the water," says Roest. However, water-resistant does not mean waterproof. "This is essential as the water surface reflects UV radiation from the sun, increasing your chances of burning." "A water-resistant sunscreen will keep working to protect your skin while you are in the water," says Roest. Aside from the cancer risks associated with sun damage, harmful rays can also cause premature ageing and pigmentation – even more reason to be wearing sunscreen," she adds. What if I tan easily, and don't burn?Īs Roest is keen to stress, "there is no such thing as a safe suntan." In fact, having a tan suggests injury has occurred, and the skin has taken measures to try and protect itself from future damage." Just because you tan at the sight of the sun doesn't mean that you shouldn't be protecting your skin. "We receive about 10 per cent of our total yearly UV exposure during the winter months, so the harmful effects of the sun are much reduced during this period, but it is still important to protect your skin. You can also develop sun-related skin damage at any time of the year. "The sun's rays can be damaging anywhere," confirms Roest. It probably won't surprise you to hear the answer to this one is yes. Do we really need to wear sun cream in the UK? If you're only applying to your face, use a dessert spoon's worth of SPF to keep you protected from the tops of your ears to the base of your neck.

The American Academy of Dermatology recommends using the equivalent of one full shot glass to cover an adult body from head to toe. Guidelines do very when it comes to the amount of sunscreen to apply, and of course the size of your body will be a factor. To be amply protected in the sun, you need a broad-spectrum suncream, which will shield from both wavelengths.Īnother factor to consider is that UVA rays can travel through glass, so it's important to wear SPF when you're sat near a window during the day. UVB rays, with a shorter wavelength, hit the surface of the skin and can cause burning.
UVA rays have a longer wavelength, meaning they penetrate further into the skin's dermis, leading to premature ageing. Moreover, there's plenty of confusion surrounding UVA and UVB rays, which both come from the sun, yet don't pose the same threat to your skin. The safe solution? Stick to SPF 30 and above, regardless of your skin type and tone, and reapply diligently. Of course, these numbers should be taken with a large pinch of salt, as they don’t consider interference from factors such as sweat and swimming. Generally speaking SPF 50 will deliver 98 per cent protection from rays, while SPF 30 offers 95 per cent. It's also important to remember to avoid spending too much time in the sun when it is at its hottest, between 11am and 3pm." "This of course is dependent on your skin and specific level of sensitivity. "If your skin type allows you to stay in the sun for 10 minutes without burning, then most commonly, wearing SPF50 will indicate that your skin will be protected for 50 times longer, so 500 minutes," explains consultant dermatologist Maria Roest. An abbreviation of ‘sun protection factor’, this number actually denotes the amount of time your skin will be protected from the sun for. What does SPF really mean?įirst, there’s the often-misunderstood SPF. In fact, there’s a lot to think about when choosing the suncream you’ll trust to protect your skin. Of course, the shelves are stacked high with endless bottles of SPF lotions, but ensuring you’re sufficiently protected from the the sun’s rays takes a little more tactic than slathering on the first cream you see.
