Choosing the Right Sunscreen: Your Essential Guide

Australia has one of the highest rates of skin cancer in the world. In fact, 2 out of 3 people will experience skin cancer at some stage in their lives. While melanoma and mortality rates have declined for those under 40, skin cancer continues to take a toll on older Australians.

Public health campaigns like ‘Slip, Slop & Slap' have raised awareness about the risks of sun exposure. The latest campaign message—Slip, Slop, Slap, Seek & Slide—adds further depth to our sun safety practices.

So, we now understand the importance of wearing sunscreen, but not all sunscreens are the same, and with so many brands available, how do you choose the right sunscreen for you?

5 Basic Rules for Sunscreen Use

Here are five essential rules to follow when using sunscreen:

1. Use a Generous Amount (Approx. 35ml for an Average Adult)

You need around 2-3 tablespoons of sunscreen to cover your face, neck, ears, arms, legs, front, and back.

2. Use a Broad-Spectrum Sunscreen

Choose a sunscreen that protects against both UVA and UVB rays.

3. Apply It 20 Minutes Before Sun Exposure

Give your sunscreen time to bind to your skin and create a protective barrier.

4. Reapply at Least Every 2 Hours

The effectiveness of sunscreens diminishes over time, so reapply regularly.

5. Apply Frequently After Swimming, Towel Drying, or Sweating

Activities like swimming and sweating can reduce the effectiveness of sunscreen.

Factors to Consider When Choosing Sunscreen

When selecting a sunscreen, consider the following:

• Product Size: How long will it last?

• Packaging Design: Is it easy to apply?

• UV Protection: Is it broad-spectrum?

• Water Resistance: Is it suitable for swimming or sports?

Mineral or Chemical Sunscreen: What's Right for You?

There are two main types of sunscreens: mineral and chemical. Both offer effective protection, but they work differently.

Mineral Sunscreens

• Contain zinc oxide or titanium dioxide.

• Create a barrier that reflects UV rays.

  
  

Pros:

• Work immediately upon application.

• Better suited for sensitive skin and those prone to breakouts.

  
  

Cons:

• Thicker texture, which can be harder to blend.

• May leave a white cast on the skin.

Chemical Sunscreens

• Use organic compounds.

• Absorb UV rays and convert them into heat, which dissipates from the skin.

  
  

Pros:

• Lightweight and easy to apply.

• Blend in more easily.

  
  

Cons:

• Take about 20 minutes to become effective.

• May cause skin irritation for some individuals.

Understanding the UV Index

You may have heard of the UV Index, but do you know what it means?

The UV Index is a standardized scale developed by the World Health Organization (WHO) to measure the intensity of ultraviolet (UV) radiation reaching the Earth's surface. It helps you manage your sun exposure.

A UV Index reading of 3 or above can cause skin damage. The Cancer Council recommends using sunscreen with an SPF of 50+ when the UV Index is at this level.

The UV Index categorizes UV radiation levels as follows:

• Low (1-2)

• Moderate (3-5)

• High (6-7)

• Very High (8-10)

• Extreme (11 and above)

Additional Sun Safety Tips

Remember, sunscreen is just one part of sun protection. Here are some additional tips to keep you safe in the sun:

• Wear a Hat: A wide-brimmed hat can provide excellent shade.

• Choose Protective Clothing: Long sleeves and pants can shield your skin.

• Wear Sunglasses: Protect your eyes from harmful UV rays.

• Seek Shade: Whenever possible, find a shaded area to relax.

By following these guidelines, you can enjoy the sun safely while protecting your skin from damage.
