Warning over suntan lotion application

Sunburn Warning.

Please remember that sunburn hurts, it’s dangerous and could bring on skin cancers.

Scientists at King’s College London say people are not getting the sun protect from sun creams that they are expecting –

And it due to the way they’re apply it !

Also please be aware of getting dehydrated – often the first indication is a headache, followed by discoloured urine, but could lead to lack of concentration, accidents (especially if driving or operation machinery) see other page chest, urethra and kidney infections – all well worth avoiding !

 

Please enjoy this wonderful weather, but PLEASE don’t become complacent !

How to apply it

Factor 50 lotion applied in the typical way would, at best, provide 40% of the expected protection, said Prof Anthony Young, whose team measured how much protection people got from wearing different amounts of suntan lotions with varying SPF strengths.

Sunscreen needs to be applied thickly enough, which many of us fail to do.

SPF ratings are based on the assumption that a 2mg blob will cover 1 sq cm of skin.

That means you should apply at least six full teaspoons (36g) to cover the body of an average adult.

More than half a teaspoon to:

  • each arm
  • the face, neck and ears

More than one teaspoon to:

  • each leg
  • chest and abdomen
  • back

Areas such as the sides of the neck, temples and ears are commonly missed, so take extra care and apply liberally.

It is also easy to forget to reapply sunscreen as often as necessary.

The British Association of Dermatologists advises:

  • Put it on 15 to 30 minutes before going out in the sun, to allow it to dry
  • Top up again shortly after heading outdoors, to cover any missed patches and ensure you’re wearing a sufficient layer
  • Reapply at least every two hours and immediately after swimming or if it has rubbed off

Some lotions say they are water resistant, meaning they retain some sun protection properties after immersion.

However, up to 85% of a product can be removed by towel drying, so you should reapply after swimming, sweating, or any other vigorous or abrasive activity.

Another important factor is the reflection of the Sun’s rays, which can greatly increase the power of the radiation: snow by up to 85% increase, sand by up to 17% and water by up to 5%.
