EBN- Longer summer days mean we’re stocking up on sunscreen. But although we all know how important it is to protect our skin from the UVA and UVB rays which can cause cancer and premature ageing, many of us still aren’t sure how best to do it.
A 2022 suncare study by La Roche-Posay1 showed that among women aged over 18, only 15% apply standalone sunscreens daily on their face, and just 48% of people in the UK wear it when the weather really calls for it.
Here, Dr Hiva Fassihi, a consultant dermatologist who specialises in skin cancer and often works with La Roche-Posay, offers the seven sun safety tips we all need to know – this summer and beyond.
1 Apply sunscreen to your face daily
Although our skin is unlikely to burn in the winter months when UVB rays are less strong, UVA rays remain constant throughout the year. UVA rays penetrate deep into our skin and damage our collagen, causing wrinkles, pigmentation and other signs of ageing.
“UVA can even come through windows and damage our skin when we’re indoors, so it’s best to wear sunscreen every day, all year,” says Fassihi. “Apply it after moisturiser and before makeup. If it’s part of your daily routine, you won’t get caught out on sunny days.”
2 An SPF moisturiser or foundation isn’t enough
If your moisturiser contains an SPF, it’s tempting to think you’re covered. That’s not the case, says Fassihi. “I always say to patients, think about what this product is primarily designed to do. If it’s primarily a moisturiser, it will be more effective at that than at protecting the skin from sun damage. You’d have to apply it very thickly to achieve the SPF it claims on the bottle, so it’s always better to begin with a base layer of actual sunscreen.”
With sunscreens available for every different type of skin, those looking to jettison one step of their routine can do so: “You could use a moisturising sunscreen which removes the need for a separate moisturiser,” she advises. “That’s much better than using a moisturiser and no sunscreen or a moisturiser that contains an SPF.”
3 Factor 50 is best
The idea of factor 50 can often seem off-putting, as people assume it will feel thick and heavy on the skin, and many believe such a high factor isn’t necessary in the UK.
However, Fassihi says: “When you look at the data about how much we’re actually applying, it can end up not delivering the necessary protection. So I’d say that using SPF 50 helps ensure you’ve still got a good level of protection.”
Formulations developed especially for the face, such as La Roche-Posay’s Anthelios UVMune 400 Invisible Fluid SPF 50+, are so lightweight they can’t be seen or felt. “When I show people in my clinic, they’re really surprised by how it disappears,” she says. “It’s ideal for underneath makeup.”
