Sunscreen Confusion

Whilst it’s always tricky delving into the medical world of do’s and don’ts, this doesn’t mean subjects should be avoided or ignored.

Today’s article around sunscreen labelling is typically confusing, so let me help. From what I’ve read, understood, and listened to from leaders in the field of melanoma – a subject I know only too well – here’s some information you need to know in relation to sunscreen;

  • SPF (Sun Protection Factor), UVA (Ultraviolet A rays), and UVB (Ultraviolet B rays), are three separate things
  • SPF (Factor 30, for example) only protects against the effects of UVB
  • UVA protection is measured by a star-rating on the back of sunscreen bottles. 4 star plus is the most effective
  • Cancer Research UK recommends applying two tablespoons of sunscreen every two hours when out in the sun in the UK
  • Experts also advise people to stay in the shade between the hours of 11:00 and 15:00 or to cover up when out in direct sunshine between these times

Conversely, read the article, and please take the information on board. Skin cancer can affect anyone and everyone, and in its worst form is DEADLY.

Two pictures for you….
