  • How To Choose The Right SPF Level When Outdoors

With all the different sunscreen options available – including natural sunscreen, baby sunscreen, and more – figuring out the best one for your skin can be tricky. Ever catch yourself wondering how to choose the right SPF? We’re here to clear up any confusion about sunscreens and SPF levels. 


What is SPF, and how does it work?

Sun Protection Factor, or SPF, is essentially a measure of how well a sunscreen will protect skin from UVB rays, the kind of radiation that can cause sunburn and contribute to skin damage. SPF values range from as low as 15 to upwards of 50, indicating the level of protection offered. 

For instance, when considering how to choose the right SPF, SPF 15 sunscreens filter out approximately 93.3 percent of UVB rays, while SPF 50 options block about 98 percent of these rays. It’s important to remember that no sunscreen can block 100 percent of UVB rays. 

Therefore, choosing a product should be based on your skin type, with SPF 30 or higher recommended for daily use and higher SPF values offering better protection for longer periods in the sun​​​​.


Misconceptions about SPF and sun protection

Many believe that a higher SPF allows for longer sun exposure without reapplication. This, however, is a misconception. SPF ratings indicate the level of protection against UVB rays, not the duration of sun exposure. It’s also worth noting that while higher SPF sunscreens offer more protection, they don’t guarantee immunity against sunburn or skin damage. 

Additionally, factors such as the time of day, cloud cover, and proximity to reflective surfaces like water and sand can affect UV radiation intensity, underscoring the importance of regular sunscreen application​​.


Understanding protection and SPF values


The essence of broad-spectrum sunscreens

Broad-spectrum sunscreens are designed to guard against the full range of the sun’s rays. Knowing how to choose the right SPF includes opting for sunscreens that are natural, sustainable, and devoid of harmful chemicals. This ensures that while you’re protecting your skin, you’re also safeguarding the environment.


The significance of SPF 30 and SPF 50+

SPF gauges how effectively sunscreen can protect skin from UVB rays. For example, an SPF of 30 implies that it would take the sun 30 times longer to redden your skin than without any sunscreen. 

Understanding how to choose the right SPF reveals that the SPF scale is not linear. Higher SPF values, such as SPF 50+, offer a very high level of protection, which is crucial for extended outdoor activities. These high SPF values, coupled with features like hydration, moisturisation, and rich antioxidant content, can help guard against premature ageing.


Understanding water resistance

Water resistance in sunscreens indicates how long the product can maintain its protective properties during water exposure or sweating. A rating of three hours of water resistance means you have ample time immersed in water or sweating before needing to reapply. 

Part of knowing how to choose the right SPF is remembering that no sunscreen is entirely waterproof, so reapplication is a must after spending time in water or sweating heavily, ensuring uninterrupted protection.


Tailoring sunscreen selection to skin type 

Choices for dry skin

Sunscreens enriched with nourishing ingredients provide deep moisturisation for dry skin. Those featuring a non-greasy, quick-absorbing formula cater to dry skin by offering sun protection without leaving a heavy feel. 


For oily or acne-prone skin

Lightweight and oil-free formulations are essential for managing oily or acne-prone skin. Choose products with ingredients like zinc oxide to prevent pore clogging and control oiliness without sacrificing hydration. 


Sensitive skin solutions

Mineral-based sunscreens containing non-nano zinc oxide are less likely to trigger skin reactions, offering a physical barrier against the sun’s rays while being free from chemicals, parabens, and fragrances. These formulations are designed to be suitable for the most delicate skin types.


Managing combination skin

A light, water-like lotion texture that absorbs quickly is ideal, ensuring the skin receives balanced hydration. Opting for fragrance-free and oil-free sunscreens suits both the dry and oily zones of combination skin, promoting comfort and protection.


Sunscreen selection with special considerations

Embracing eco-friendly and reef-friendly options

The call for eco-friendly, like reef-safe sunscreen, grows louder as we understand more about the detrimental effects certain chemicals have on marine ecosystems. Steering clear of harmful ingredients like oxybenzone and octinoxate, which have been linked to coral reef damage, is a step towards diligent sun care. 


Sunscreens tailored for children and sensitive skin

For the younger members of the family and those with sensitive skin, the selection process becomes even more critical. Sunscreens that use mineral-based formulas offer a gentle yet effective barrier against the sun’s rays without the harshness found in chemical sunscreens. 

These products rest on the skin’s surface to reflect UV rays, minimising the risk of irritation or allergic reactions, making them an ideal choice for sensitive skin types.


Innovations in sunscreen: beyond basic protection

The sunscreen market has evolved to include tinted and enhanced formulations, catering to a wider range of skin tones and offering additional benefits beyond UV protection. Tinted options not only guard against the sun but also help even out skin tone for a more natural, radiant finish. 

Meanwhile, enhanced formulas can offer antioxidants, hydrating ingredients, and anti-ageing benefits, elevating sunscreens to a multifaceted skincare solution. These innovative products allow for seamless integration into daily skincare routines, addressing specific concerns while guarding against sun damage.


Frequently Asked Questions (FAQ)

Can sunscreens expire, and how does this affect their effectiveness?

The Therapeutic Goods Administration (TGA) requires sunscreens to have an expiration date because the active ingredients can degrade over time, reducing their effectiveness. It is generally recommended not to use sunscreen past its expiration date. 


How much sunscreen should be applied to ensure full protection?

The Cancer Council Australia recommends applying at least one teaspoon of sunscreen to each arm, leg, face (including the neck and ears), front of the body, and back of the body. This amounts to approximately 35 ml of sunscreen for a full-body application. 


How should sunscreen be stored to maintain its effectiveness?

Sunscreens should be stored in a cool, dry place, away from direct sunlight and excessive heat. This is particularly important in Australia’s hot climate, as temperatures in a car or on the beach can exceed what sunscreen products can withstand without degrading. 

The TGA recommends avoiding storing sunscreen at temperatures above 30°C. If sunscreen has been exposed to high temperatures or has changed in colour, consistency, or smell, it may be less effective and should be replaced.


Enjoy the outdoors with the right sunscreen 

Selecting a sunscreen that matches your daily habits and activities is crucial for ensuring that you use it consistently. If you’re often outdoors or involved in water sports, water-resistant sunscreens are a practical choice. 

For those with sensitive skin, mineral-based sunscreens offer a gentler option, whereas oil-free formulas might be preferred by those with oily skin types. The key is to find a sunscreen that feels like a natural part of your daily routine, ensuring that you’re protected whenever you step outside .


Key Points to Remember

  • Understanding SPF. SPF measures sunscreen’s protection against UVB rays, which can contribute to skin damage and sunburn. There are different levels of SPF with varying levels of protection, but no sunscreen blocks 100 percent of UVB rays.
  • Choosing the right SPF. Select sunscreen based on your skin type and exposure time. Use SPF 30 for daily activities and SPF 50+ for longer outdoor exposure.
  • Misconceptions about SPF. High SPF doesn’t eliminate the need for reapplication; sunscreen should be reapplied every three hours or less, particularly when swimming or heavily sweating.
  • Broad-spectrum sunscreens. Choose broad-spectrum sunscreens to help protect against both UVB and UVA rays.
  • Water resistance. Water-resistant sunscreens need reapplication after swimming or sweating despite their temporary water resistance.
  • Tailoring to your skin type. Match sunscreen to your skin type – whether dry, oily, sensitive, or combination – to ensure effective protection and skin health.
  • Eco-friendly choices. Choose sunscreens without oxybenzone and octinoxate to protect marine ecosystems and coral reefs.
  • For sensitive skin and children. Use mineral-based, non-nano zinc oxide sunscreens for gentle, effective protection suitable for delicate skin.
  • Sunscreen innovations. Modern sunscreens may offer tinting, hydration, antioxidants, and anti-ageing benefits, enhancing skin health beyond UV protection.
  • Storage and expiry. Store sunscreen in a cool, dry place and adhere to the expiration date to maintain its effectiveness.
  • Application quantity. Apply about 35 ml of sunscreen for full body coverage, ensuring adequate protection.
