Beauty & tech: Find out what the sun is doing to your skin with the La Roche Posay UV Patch

October 2, 2017
You've probably heard that skin cancer is more common than all the other cancers combined, but that it's mostly preventable, and that if detected early, it is curable.
You've probably also heard that it's important to wear sunscreen, and how dangerous the sun is. But how do you know when you're adequately protected, and if it's time to reapply?
This is where the My UV Patch from leading French skincare brand comes in. Together with a mobile app, it monitors your skin's exposure to UV rays throughout the day.

How it works

The My UV patch is a blue adhesive that contains photosensitive dyes that change colour when exposed to UV rays, which indicate varying levels of sun exposure. Stick it on your arm or hand, and wear it for up to five days (it fine to swim or shower with it – mine wrinkled at the edges a bit, but it was still readable). Apply sunscreen to the patch, enter your details into the free app, and scan the patch with the app when it tells you to (around every half hour).

Through an algorithm that takes into account your phototype, skin type, location and weather, when the app scans your patch, it will tell you whether or not you're being sun safe, and if it's time to apply sunscreen. The app will also tell you how much UV exposure you've had during the day, and when you've had too much sun. It will also even tell the ideal La Roche Posay Antehlios product and SPF level to use.

What the research shows

La Roche Posay survey results showed that:

  • 63% experienced less sunburn
  • 37% used more facial sunscreen
  • 31% tried to stay in the shade more


How it could help you

No one is saying you should be wearing a patch every day, but, as they say, knowledge is power, and knowing a bit about your coverage and how you generally react to the sun is useful. It's also safe to use on kids, and you could get great insight into their coverage, and how often you should be reapplying (remember: infant and kids' skin is a lot more delicate than ours, so it's useful to know about what protection suits them and how often to apply, rather than just guess.




Where can you get a MyUVPatch?

    I used to think all sunscreen was the same
    But I learnt the higher the SPF the better. And with the harsh sun conditions we get this patch is great especially with summer approaching and some
    Spring days already feeling like summer
