Why SPF50+ Sunscreen Is a Must 

Range of suncream products

The Port Macquarie region is known for its beautiful beaches, outdoor lifestyle, and abundant sunshine. But with that sunshine comes a serious health risk. Australia has one of the highest rates of skin cancer in the world (Cancer Council Australia). That’s why wearing SPF50+ sunscreen isn’t just a summer tip, it’s a year-round necessity.

The Harsh Reality of our Aussie Sun

Australia’s location means we’re exposed to more intense UV radiation than many other parts of the world. The ozone layer over the Southern Hemisphere is thinner, especially during summer, allowing more harmful UVB rays to reach the surface. These rays are the primary cause of sunburn and play a major role in the development of skin cancers, including melanoma (ARPANSA).
Why SPF50+?
SPF stands for Sun Protection Factor, and the measure of how long it takes for the skin to redden or burn as compared to skin without protection. Here’s why SPF50+ is the gold standard:
  • Blocks 98% of UVB rays (compared to 93% for SPF15 and 97% for SPF30)
  • Provides longer protection, especially when reapplied every 2 hours
  • Reduces the risk of skin cancer, premature aging, and sunburn (SunSmart)
In a country where UV levels can be extreme, even on cloudy days, that extra percentage of protection can make a big difference.
It’s Not Just for the Beach
Many of us still associate sunscreen with beach days or summer holidays. But UV radiation is present every day, and it can penetrate clouds and glass. Whether you’re walking the dog, driving to work, or sitting by a window, your skin is still at risk (Cancer Council Fact Sheet).
Long-Term Benefits
Regular use of SPF50+ sunscreen can:
  • Prevent DNA damage that leads to skin cancer
  • Reduce signs of aging like wrinkles, sunspots, and sagging
  • Maintain an even skin tone and healthier skin overall
Tips for Effective Use
  • Apply 20 minutes before sun exposure
  • Use a generous amount—about a teaspoon per limb, and one for the face and neck
  • Reapply every 2 hours, or after swimming or sweating
  • Don’t forget ears, lips, and the back of your neck
Wearing SPF50+ sunscreen is one of the simplest and most effective ways to protect your health in our sun-drenched climate. It’s not just about avoiding sunburn — it’s about preventing skin cancer and preserving your skin for years to come.
