Sunscreen…always a hot topic

14 July 2024

Hello, sunshine lovers, Nicola here. We all know wearing sunscreen reduces the risk of skin cancers and is your best ally against the signs of ageing, but it can be confusing choosing the right one for you and your family.

So, grab your favourite sun hat, and let’s dive deep into the SPF, UVA and UVB of it all.

UVA and UVB

Both UVA and UVB rays can harm your skin.

UVB rays are the main culprit behind sunburn, while UVA rays penetrate deeply, causing premature ageing and some skin cancers. Together, they’re a duo we need to avoid.

A simple way to remember is:

UVA = Ageing
UVB = Burning

SPF explained

SPF stands for Sun Protection Factor. It measures how well a sunscreen protects against UVB rays – those are the ones that cause sunburn and contribute to skin cancer.

For most people, we recommend an SPF of at least 30. Higher SPF numbers mean more protection, but don’t let those numbers fool you. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. Remember, no sunscreen can block 100% of UV rays.

The star rating system

SPF refers to UVB protection only. In addition to the SPF you need to check the star rating on your sunscreen.

This star rating tells you how good the sunscreen is at protecting against UVA rays. Ideally look for 5 stars. 3 or less than choose another product.

Broad-spectrum protection

Always opt for a broad-spectrum sunscreen, which protects against both UVA and UVB rays advises Suné, And wear it every day of the year – sunscreen is necessary even on cloudy days, as up to 80% of UVA rays can pass through clouds and glass.

Chemical vs. Physical sunscreen

Did you know sunscreens come in two main types: chemical and physical.

Chemical sunscreens soak up the sun’s rays like a sponge, while physical (or mineral) ones act like a mirror, reflecting UV rays away from your skin.

Suné's top tip: For children or those with sensitive skin, mineral-based sunscreens with ingredients like zinc oxide or titanium dioxide are often less irritating.

Choosing the right sunscreen

There’s a sunscreen for every skin type. For oily skin, look for “non-comedogenic” on the label to prevent clogged pores like Oil Free Matte SPF30 which is non-greasy and light. Dry or Aging skin? Try Dynamic Skin Recovery SPF50 which helps moisturise as it protects and its great for mature or pre-mature aging skin.

Tinted sunscreens are great multi-taskers, offering protection while evening out your skin tone. Do ask us for the best one for your skin tone and type. My personal favourite is Skinperfect Primer SPF30 which I use over my Dynamic Skin Recovery SPF50 moisturiser.

“Planning a swim or a sweat? Water-resistant sunscreens are your best bet. I’m popping Protection 50 Sport SPF50 into my suitcase this summer. But remember, “water-resistant” doesn’t mean “waterproof.” Reapply every 80 minutes, and immediately after a dip or an exercise session.”

Application tips for maximum protection

Apply a generous amount of sunscreen to all exposed skin 30 minutes before going outdoors – about a shot glass full for the body.

And remember to reapply every one to two hours, or immediately after swimming or sweating – even if you’re using a high-SPF or water-resistant product.

Remember your ears, tops of feet, back of the neck and your scalp need sunscreen love too, says Suné. “And don’t forget the lips – a lip balm with SPF is a must, especially for any one with Lip Blush treatments.

If you have Semi-Permanent Brows (Microblading/Tattooing) always remember to apply a sunscreen over them, this will prevent discolouration or colour drift (unwanted yellowing or grey tones) of the pigment and will keep your brows looking fresher for longer. Use KBPro Grow and Protect SPF50 Serum which will absorb and prevent damage caused by UVA and UVB rays

And a word of caution. Even if your foundation contains an SPF don’t rely on it for protection as you’re unlikely to apply it thickly enough. Apply your usual sunscreen, then your foundation. Depending on how much coverage you want, a tinted SPF could replace your foundation altogether.
