Why SPF is a Summer Essential
Protecting Your Skin in the Australian Sun
As summer blooms across Australia, bringing with it longer days and increased sunshine, it's a perfect time to discuss why sunscreen (SPF) remains your skin's best friend. While we often relish the return of warm weather and sunny days, it’s crucial to approach sun exposure with caution, especially given Australia's high rates of skin cancer.
The Australian Sun: A Beautiful Yet Harsh Reality
Australia experiences some of the highest levels of ultraviolet (UV) radiation in the world. This is due to its proximity to the equator and a number of clear, sunny days throughout the year. According to the Cancer Council Australia, 2 in 3 Australians will be diagnosed with skin cancer by the time they are 70. Additionally, melanoma, the most dangerous form of skin cancer, is the third most common cancer diagnosed in Australian men and women.
These statistics are not just numbers; they are a call to action. The good news is that most skin cancers can be prevented, and a significant factor in prevention is the effective use of sunscreen.
Understanding SPF and Its Importance in Summer
SPF, or Sun Protection Factor, measures a sunscreen's ability to protect skin from UVB rays—the type of radiation that causes sunburn and contributes to skin cancer. However, it's also important to choose broad-spectrum sunscreens, which protect against both UVA (aging rays that can also contribute to cancer) and UVB rays.
Summer in Australia isn't just a transitional period between the cold and heat; it's often a time when UV levels start to rise significantly. Despite the mild temperatures, the UV index often reaches very high to extreme levels during the middle of the day. This means unprotected skin can be damaged in as little as 10 to 15 minutes.
SPF Under Makeup: Integrating Sun Protection Into Your Daily Routine
One common misconception is that the SPF in makeup is sufficient for protection against sun damage. While some foundations and powders contain SPF, they are usually not applied heavily enough to achieve the full SPF rating listed on the product.
The solution? Apply a dedicated broad-spectrum sunscreen with at least SPF 30+ under your makeup each morning. Ensure you apply it to all exposed skin, not just your face—remember your neck, ears, and hands, which are often neglected.
Best Practices for Sunscreen Application in Summer
Here are some tips to maximise your sun protection this summer:
Apply Early and Generously: Sunscreen should be applied 20 minutes before you go outdoors and in generous amounts. The Cancer Council suggests at least one teaspoon for each limb, as well as for the front and back of the body, and half a teaspoon for the face, neck, and ears.
Reapply Regularly: Sunscreen should be reapplied every two hours, or more often if you are sweating or swimming. Remember, water resistance in sunscreen doesn't mean waterproof. It still needs frequent application.
Seek Shade and Wear Protective Clothing: Sunscreen is just one part of a comprehensive sun protection strategy. Seek shade during the hottest parts of the day, typically from 10 AM to 2 PM, and consider wearing sun-protective clothing, a broad-brimmed hat, and UV-protective sunglasses.
Be Mindful Even on Cloudy Days: Up to 80% of UV rays can penetrate light cloud cover, which means you’re at risk of sun damage even on overcast days.
Summer Forward with Healthy Skin Habits
As you enjoy the beautiful summer weather, remember that taking care of your skin is a year-round commitment. By integrating SPF into your daily routine, you not only protect yourself from immediate sunburn but also contribute to your long-term skin health, preventing premature aging and reducing your risk of skin cancer.
Summer is a wonderful time to reinforce good skincare habits. As the landscape rejuvenates and blossoms, let your skin care routine flourish too, with SPF as a cornerstone of your daily practices. Remember, a little precaution goes a long way in maintaining healthy, radiant skin in the Australian sun.
