Australia boasts some of the most beautiful outdoor environments in the world, from pristine beaches to expansive outbacks. However, it also has one of the highest rates of skin cancer globally. The Australian sun, while a source of enjoyment and vitamin D, poses significant risks if adequate precautions aren’t taken.
Understanding the risks associated with UV exposure and taking proactive measures like using sunscreen are crucial for skin cancer prevention.
What causes skin cancer?
Skin cancer arises primarily from the skin’s exposure to ultraviolet (UV) radiation. In Australia, skin cancers account for the largest proportion of cancers diagnosed each year. There are several types of skin cancer, but the most common include basal cell carcinoma, squamous cell carcinoma, and melanoma, the deadliest form.
The good news is that most skin cancers are preventable. An essential step in combating this disease is understanding and implementing effective sun protection strategies.
Understanding the impact of Ultraviolet Radiation (UV)
UV levels, or ultraviolet radiation levels, indicate the strength of the sun’s UV rays at a specific time and place. These levels are crucial to understanding because they help gauge the potential risk of sun exposure, which is directly linked to skin damage and the development of skin cancer.
UV index levels
The UV Index is a standard measurement used worldwide to forecast the strength of the sun’s ultraviolet radiation at the Earth’s surface. The index is typically scaled from 1 to 11+, where:
- 1-2 indicates low exposure risk,
- 3-5 suggests moderate risk,
- 6-7 signals high risk,
- 8-10 denotes very high risk, and
- 11+ indicates extreme risk.
The UV Index helps people plan safer outdoor activities by indicating when to seek shade, wear protective clothing, and use high-SPF, broad-spectrum sunscreen.
Understanding these levels promotes better sun safety education, enabling informed protective measures against skin cancer, premature aging, and other UV-related harms.
It also guides tailored protection based on activity and skin type and helps prepare for heat-related risks on high UV days, underscoring the importance of hydration and heat avoidance.
The role of sunscreen in preventing skin cancer
Sunscreen is a powerful tool in the fight against skin cancer. It works by absorbing, reflecting, or scattering sunlight, thereby protecting your skin from harmful rays. The efficacy of sunscreen is measured by its Sun Protection Factor (SPF).
The SPF indicates the level of protection against UVB rays, responsible for sunburn and a significant risk factor for skin cancer. However, it’s important to choose a broad-spectrum sunscreen which also protects against UVA rays, known to penetrate deeper into the skin and accelerate skin aging.
Using sunscreen appropriately can significantly reduce the risk of developing skin cancer. A study by the Cancer Council Australia suggests that regular sunscreen use can cut the incidence of melanoma, the most serious type of skin cancer, by up to 50%.
How to apply sunscreen correctly
To maximise the effectiveness of sunscreen, it should be applied generously and evenly. Here are some tips for correct application:
- Apply sunscreen to all exposed skin, including areas like the ears, back of the neck, and tops of feet.
- Use about one teaspoon of sunscreen for each arm, leg, the front of the body, the back of the body, and the face (including neck and ears).
- Sunscreen should be applied 20 minutes before going outdoors and re-applied every two hours, or more often if swimming or sweating.
Choosing the right sunscreen
Here are key factors to consider when selecting the right sunscreen for your needs:
- Opt for a broad-spectrum sunscreen with an SPF of at least 30.
- Consider water-resistant options if you are engaging in water activities or sports.
- For sensitive skin, look for sunscreens with physical blockers like zinc oxide or titanium dioxide, as they are less likely to irritate.
LFA First Response offers a range of sunscreens, offering the highest level of sun protection at SPF 50+, ensuring you can stay protected from the sun’s harsh UV rays. Available in up to 1L pump bottles, these sunscreens are ideal for school or sports settings.
Dealing with sunburn
Despite taking precautions, sunburn can occur. This is where aftercare products come into play, such as burn gels. These aftercare products are formulated to cool the burn, help reduce inflammation, and hydrate the skin, aiding in the skin’s healing process. Alongside applying burn gel to soothe the skin, keep hydrated, avoid the sun and avoid thick body creams which can trap heat in.

This global day serves as a reminder to protect your skin from the sun throughout the year. It’s the ideal opportunity to review and renew your commitment to daily sun protection habits.
The importance of skin checks
Skin checks are vital for preventing skin cancer as they enable early detection of suspicious moles or skin changes, increasing the chances of successful treatment. Regular monitoring allows for the identification of new spots or changes in existing moles, which are crucial indicators of skin cancer.
Dermatologists can spot atypical moles that may be precursors to cancer, and provide guidance on sun protection and self-examination. This not only enhances survival rates, particularly for aggressive forms like melanoma, but also offers peace of mind through proactive skin management.
Regular skin checks are especially important for those with risk factors such as fair skin, a history of sunburns, or a family history of skin cancer.
Stay protected all year round
Skin cancer prevention goes beyond just a single day of awareness—it’s about making sun safety a part of your everyday routine. Remember, the risk of sunburn persists even on cloudy days. By consistently applying sun protection correctly as part of your daily habits, you can significantly lower your risk of developing skin cancer and keep your skin healthier.
