Why You Should Be Wearing SPF Every Day

If you’ve mentally packed away your SPF with the flip-flops, consider this your polite, newspaper-style intervention. Britain doesn’t stop producing ultraviolet (UV) radiation just because the calendar has turned and the skies have adopted their familiar “grey with a chance of more grey” look. The sun is still doing sun things; we’re just less likely to notice—until our skin does.

Cosmetify has released a new UK tool designed to help you match sunscreen strength to where you live and what UV typically looks like across the year. It’s called the UK SPF Index, and it lets you check your average UV rating by month—handy for anyone who wants a simple answer to a not-so-simple question: what SPF should you actually be wearing?

You can also cross-check current daily UV figures via the Met Office, but the point is the same: use the UV Index to guide your SPF, not the season.

The UK UV Index cheat sheet: what SPF to use and when to reapply

Use this guide from Cosmetify to determine the level of protection you’ll need:

• Low Risk (UV 0–2): SPF 15 — Reapply every 2 hours — Sunglasses
• Medium Risk (UV 3–5): SPF 30 — Reapply every 2 hours — Sunglasses, hat
• High Risk (UV 6–7): SPF 30 — Reapply every 2 hours — Sunglasses, hat, shade, SPF lip balm
• Very High Risk (UV 8–10): SPF 50 — Reapply every 2 hours — Sunglasses, hat, shade, SPF lip balm, find shade between 10 am–4 pm
• Extremely High Risk (UV 11+): SPF 50 — Reapply every 2 hours — Sunglasses, hat, shade, SPF lip balm, stay indoors between 10 am–4 pm

That’s the backbone. The smarter move is making it routine: check the UV, choose the right SPF, apply properly, and reapply like you mean it.

“One of the biggest beauty and health hacks is SPF” — and it’s being ignored

Cosmetify’s PR Manager, Iman Bokolo, doesn’t dress this up. She’s essentially saying we’re treating sunscreen like it’s optional—when it’s one of the most basic, high-return habits you can adopt.

When it comes to protecting your skin from the sun, Iman Bokolo, PR Manager, comments: “One of the biggest beauty and health hacks is SPF, and sadly it is forgotten about or deemed not important. Even on cloudy days, the sun is so powerful that up to 80% of the rays can pass through clouds, and even snow can reflect up to 80% of UV rays. Not only this, but the higher the altitude, the greater the exposure, so going for a hike on a cloudy day definitely calls for SPF.

Most of us know the importance of SPF in summer, but it should be considered a year-round health measure. No matter your skin colour, sunscreen should be your number one health and beauty tool. Even if you wear foundation, for maximum protection SPF should be applied directly on the skin.

Not only does it protect your skin from harmful UV rays and lower your skin cancer risk, but it also prevents premature skin ageing and helps to maintain a smooth and even skin tone.

When choosing your sun cream, make sure to check the UVA protection as well as the SPF, opting for a product with at least 4-star UVA protection.

You should also choose a lip balm with SPF in order to protect the delicate and fragile skin on your lips. For full protection, choose a hair protector that moisturises and protects from harmful UV rays.

Once you have the right protection, make sure to use it right by reapplying after swimming, towel drying, or sweating, especially in significantly warmer weather You should also reapply every two hours to make sure you are well protected, ensuring to apply liberally to any part of your skin that is exposed.”

Translation: SPF is not a “hot day” product. It’s a daily behaviour—like brushing your teeth, except your teeth don’t usually peel in sheets if you forget.

Mineral vs chemical SPF: what’s best for your skin and lifestyle?

If sunscreen shopping feels like wading into a swamp of marketing claims, Leah Armitage from Alpha Aesthetics offers a practical dividing line: physical (mineral) versus chemical.

Leah Armitage, from Alpha Aesthetics comments: “Sun protection is so often overlooked but it needs to be worn every day, regardless of the weather and regardless of your skin type. The best SPF (sun protection factor) are products which contain zinc or titanium dioxide and are referred to as physical or mineral sun protection.

This type reflects UV radiation away from the skin, whereas a chemical sunscreen, which is usually more oily and alcohol-based, absorbs UV radiation and disperses it as heat. Physical sunscreens are also more appropriate for those with sensitive skin such as rosacea because there are less chemical ingredients.

Chemical sunscreens, however, are better for those who exercise frequently as they absorb quicker and do not tend to sweat off as quickly.

That being said, always check the product as most will need reapplying every 2 hours for maximum efficacy. Always make sure you apply to your face but do not neglect your neck and hands!

Make sure your products are marked 4 stars for UVA and that the UVA label is in a circle. Make sure it also covers UVB. UVA is responsible for ageing and accounts for 95% of UV radiation and is the same intensity every single day.

UVB is responsible for burning and the intensity fluctuates throughout the seasons and time of day.“

The takeaway is refreshingly unglamorous: pick the right SPF texture for your skin and your day, then apply enough and reapply often enough for it to count.

How to actually use SPF properly (the part most people skip)

A lot of people “use SPF” the way they “do strength training”—technically true, but not in any way that would impress a professional.

Here’s the evergreen, practical routine:

• Check the UV Index (monthly averages via the Cosmetify tool; daily updates via the Met Office).
• Match SPF to UV: SPF 15 for very low UV; SPF 30 for moderate; SPF 50 for high and above.
• Apply to bare skin first, then makeup on top (foundation with SPF is not the same as a dedicated layer).
• Don’t miss the usual neglected areas: ears, hairline, neck, chest, backs of hands.
• Reapply every two hours as standard—and sooner after swimming, sweating, or towel drying.
• Don’t forget lips and hair if you’re exposed for long stretches: SPF lip balm and UV-protective hair products are not just “extras” if you burn easily or spend time outdoors.

This is how SPF becomes effective protection, rather than a comforting bottle that lives in a drawer.
