We often assume skin cancer and sun safety isn’t a major concern in the UK—after all, we’re more used to reaching for umbrellas than sunglasses. But with around 1 in 40 people in the UK developing melanoma (the most serious form of skin cancer, that if left untreated can spread and even be fatal) during their lifetime, it’s an issue none of us can afford to ignore. In fact, because sunshine feels like such a rare treat here, we’re more likely to underestimate its risks, making us more prone to sunburn and long-term skin damage.
Whether you’re holidaying abroad or spending a sunny afternoon in the garden, it’s important to take steps to protect your skin. Here are seven key things to know to help you and your family stay safe in the sun.
The Right Amount: Are You Applying Enough?
Most of us underestimate how much sunscreen we actually need. To be effective, you should be using around 40ml (about a shot glass or two tablespoons) for a full-body application, 20 minutes before sun exposure.
With the average bottle containing 200–250ml, that means a single bottle should only last for six or seven applications per person. If yours is stretching for a week or more, it’s a sure sign you aren’t applying enough.
Frequency Matters: Why You Must Reapply
Despite what some products claim, no sunscreen lasts all day—especially when swimming, sweating, towelling off, or simply being active outdoors.
To maintain protection, reapply every two hours, or more frequently if you’ve been in the water or wiped your skin. Even “water-resistant” formulas need topping up to remain effective.
Shade Isn’t Sufficient on Its Own
While it’s wise to avoid direct sunlight between 11am and 3pm, being in the shade doesn’t mean you’re fully protected.
“UV rays reflect off sand, water, snow and even concrete.” says Dr Caroline Morgan, Consultant Dermatologist. “Even when in the shade there can be significant UV exposure, so using an SPF 30+ with 5 star UVA rating is essential to protect you and your family’s skin against sun damage.”
So, even when you’re under a parasol or tree, sunscreen is still essential.
Covering Up: The Role of Protective Clothing
Sunscreen can be tricky to apply on children who just want to dash off to play. That’s where UV-protective clothing comes in.
Rash vests, wide-brimmed hats (many come with a neck covering) and long-sleeved swimwear offer added protection, and can offer a less stressful way of protecting your children, without having to run after them with a bottle of suncream. Children’s skin can burn more easily than adult skin, so needs extra protection. It is thought that just five episodes of sunburn during childhood can double a person’s risk of skin cancer later in life.
SPF: Not Just for Holidays
UV rays are present all year round—even in the UK, and even when it’s cloudy. Up to 80% of UV rays can pass through clouds, meaning that your skin can be damaged even on overcast days.
That’s why it’s recommended to use a broad-spectrum SPF 30+ sunscreen with a 5 star UVA rating, particularly on areas that are regularly exposed to the sun, such as the face, neck, and hands—regardless of the weather.
It’s true that sunlight helps the body produce vitamin D, and some people worry that sunscreen blocks this process. However, research shows that typical sunscreen use does not significantly prevent vitamin D production. Your skin can still make vitamin D when exposed to UVB rays, even with sunscreen applied—especially when used in real-world conditions, where coverage is often uneven or incomplete.
Sun Safety for Children: Start Early
Children’s skin is more sensitive to UV damage, and early exposure increases the risk of skin cancer later in life. “I recommend using a child-friendly SPF 50+ 5 star UVA rated sunscreen, ideally one that’s water-resistant and formulated for sensitive skin.” says Doctor Caroline Morgan, Consultant Dermatologist.
Make sun safety part of their daily routine—let them choose their hat, or turn applying sunscreen into a fun game to encourage cooperation.
Darker skin tones still need protection
People with darker skin tones have more melanin, which offers some natural protection against UV damage—but it doesn’t make them immune to sunburn or skin cancer. In fact, skin cancer in Black and brown skin is often diagnosed at a later stage, making it more dangerous. Melanoma may appear in less obvious places, like the palms, soles, or under nails. Sun protection is still essential: use broad-spectrum sunscreen (SPF 30 or higher), wear protective clothing, and check your skin regularly for changes.
Regardless of skin tone, everyone needs to be sun safe to reduce long-term health risks.
Skin Awareness: Know What to Look For
Even with the best protection, it’s important to monitor your skin regularly. Watch for new moles or changes to existing ones—including changes in size, shape, colour, or sensation.
If you notice anything unusual, see your GP or a dermatologist. Skin cancers are far more treatable when detected early.
It’s Never Too Late
Despite many of us only using “low factor” sunscreens or not at all in our youth, it is never too late to start to protect your skin from further sun damage. A baseline skin check with a dermatologist or GP will teach you how to protect your skin, identify any areas that need treatment or monitoring as well as teaching you what you should be keeping an eye out for in the future.
