It’s a given that most of us will protect our skin while at the beach or on holiday, but we do tend to forget it when cycling to work or hanging at a sporting event. By wearing sunscreen correctly – and daily – you’ll not only help prevent scorching your skin, but you’ll also help prevent sun damage, lessening your chance of serious damage that is irreversible. Sun exposure is also responsible for the visible ageing of your skin – far more than any other factors combined. If premature ageing isn’t a good enough reason to wear sunscreen daily, then what is?!
Sunscreens are products that combine several ingredients that help prevent the sun's ultraviolet (UV) radiation from reaching the skin. Two types of ultraviolet radiation, UVA and UVB, damage the skin, age it prematurely, and increase your risk of skin cancer. UVB is the chief culprit behind sunburn, while UVA rays, which penetrate the skin more deeply, are associated with wrinkling, leathering, sagging, and other light-induced effects of ageing. They also increase the carcinogenic effects of UVB rays, and are increasingly being seen as a cause of skin cancer on their own. Sunscreens vary in their ability to protect against UVA and UVB.
Athlete Performance’s Luxury Moisturiser with SPF 15 will protect from both UVA and UVB rays. Ideal to use before and during any sporting activity, and formulated to hydrate, calm and refresh, our Luxury Moisturiser with SPF 15 contains natural ingredients, like avocado oil and cocoa butter, both widely accepted for their beneficial skin care properties.
If your skin would normally burn after 10 minutes in the sun, applying an SPF 15 sunscreen would allow you to stay in the sun without burning for approximately 150 minutes (a factor of 15 times longer). This is a rough estimate that depends on skin type, intensity of sunlight and amount of sunscreen used.
Most people under-apply sunscreens, using ¼ to ½ the amount required. Using half the required amount of sunscreen only provides the square root of the SPF. So, a half application of an SPF 15 sunscreen only provides an effective SPF of 3.7!
For best protection, we recommend using a minimum SPF of 15 when engaging in outdoor activities. Applying the proper amount (2mg/cm2 of skin, or about one ounce for full body coverage), and reapplying every 2 hours.
The SPF scale is not linear:
- SPF 15 blocks 93% of UVB rays
- SPF 30 blocks 97% of UVB rays
So, one way of looking at this is that SPF 30 sunscreen only gives you 4% more protection than SPF 15 sunscreen.
Or, another way of looking at it is:
- SPF 15 (93% protection) allows 7 out of 100 photons through
- SPF 30 (97% protection) allows 3 out of 100 photons through.
The sun is relentless and doesn't take a break, emitting harmful UV rays all year round, even on cloudy days – approximately 80% of UV rays still penetrate through the clouds. Whatever your skin type, UV rays can damage your skin without daily sun protection. The sun doesn't discriminate! The damage might not be immediately visible but it will be no less real. And, don’t think your clothes will protect you either! Harmful UV rays can penetrate fabrics, especially loosely woven ones. The average white T-shirt has an SPF of approximately 7 – considerably below the standard recommendation for sunscreen of SPF 15. Similarly, a beach or garden parasol may only provide partial protection.
Final word – slip, slap slop as the Ozzie saying goes!
