Understanding Different Types of UV Rays
When it comes to understanding sunscreen, it’s important to know that not all ultraviolet (UV) rays are the same. There are two primary types of UV radiation that affect our skin: UVA and UVB, each with distinct characteristics and effects. UVA (Ultraviolet A) rays are responsible for causing long-term damage to the skin, including premature aging, such as the development of wrinkles and fine lines. UVA rays can penetrate the skin more deeply and are present year-round, even on cloudy days. UVB (Ultraviolet B) rays are primarily responsible for causing sunburn and more immediate skin damage. They affect the top layers of the skin and are most intense during the summer months when the sun is at its peak. To effectively protect your skin against both forms of UV rays, it’s important to use a broad-spectrum sunscreen.

Choosing Between Mineral and Chemical Sunscreens
Sunscreen options can be divided into two main types: mineral and chemical. Mineral sunscreens use active ingredients like zinc oxide or titanium dioxide. When you apply them, they act like a protective layer on your skin’s surface, bouncing away or scattering the harmful UV rays. They start working immediately and are ideal for sensitive skin and children. However, the downsides are that they can sometimes feel a bit sticky and may leave a white cast – especially on darker skin. On the other hand, chemical sunscreens contain ingredients like avobenzone, octisalate, octocrylene, or oxybenzone. These chemicals absorb the UV rays and change them into heat, which your skin then releases. Chemical sunscreens aren’t immediate like mineral sunscreens, taking about 20 minutes to start working. People with especially sensitive skin might also prefer the gentler mineral sunscreens. However, the upsides for chemical sunscreens are that they are usually lightweight, feel good on the skin, are cosmetically elegant and don’t leave a white tint. Your choice between mineral and chemical sunscreen depends on your personal preference, but always make sure it’s labelled as “broad spectrum” to protect against both UVA and UVB rays.

Decoding SPF: What Sun Protection Factor Really Means
SPF, or Sun Protection Factor, is important to understand when it comes to sunscreen. It’s a numerical indicator that shows how well a sunscreen can protect your skin from the sun’s harmful rays. But a common misconception is that a higher SPF means much better protection. In reality, it measures how much longer you can stay in the sun without getting a sunburn compared to not wearing any sunscreen at all. For example, if you’d typically get a sunburn in 10 minutes without any protection, using our Defence SPF 50 might let you stay in the sun about 50 times longer, or 500 minutes, before getting burned. Our Moisturiser with SPF 15 on the other hand might allow you to stay in the sun 15 times longer, or 150 minutes. However, it’s not as simple as just multiplying the number. The actual level of protection depends on things like your skin type, how strong the sunlight is, and how long you’re out in it. And it’s important to always follow the manufacturer’s instructions to make sure you’re adequately protected.

The Importance of Sunscreen Reapplication
Applying sunscreen is an important first step to shield your skin from the sun, but it’s important to know that putting it on once isn’t enough. Sunscreen loses its strength over time, especially when you sweat, get wet, or stay in the sun. To keep your skin well-protected, you must reapply. The general advice is to do this every two hours. But if you’re swimming, sweating a lot, or drying off with a towel, you should reapply even more often because these activities can make sunscreen less effective.

Proper Application Techniques for Effective Sun Protection
To make sure you’re protecting your entire body with sunscreen, most adults need to use around 40 millilitres (about 8 teaspoons). However, it’s important to pay attention to the directions on the sunscreen label. The amount you need can vary between different types of sunscreen. For instance, aerosol sprays might need more than creams or lotions because they contain a propellant. So, always follow the instructions provided on the product to make sure you’re using it effectively.

Government Regulations Ensure Sunscreen Safety
You can trust sunscreen instructions and SPF ratings because governments and health agencies worldwide have set rules to make sure you can make good decisions and rely on the protection sunscreen offers. In Australia, we’re lucky to have some of the toughest rules globally. Australian sunscreens are known worldwide for being effective, and that’s because of the strict standards set by the Therapeutic Goods Administration (TGA). In New Zealand, sunscreen products are regulated by the Ministry of Health under the Medicines Act 1981 and the Medicines Regulations 1984, with the New Zealand Environmental Protection Authority (EPA) ensuring that sunscreen ingredients comply with environmental standards. When you’re picking a sunscreen, always choose one that’s registered with the TGA in Australia or compliant with New Zealand’s regulations. This ensures the product has met rigorous safety and effectiveness criteria. Homemade sunscreens, on the other hand, are not regulated, and their effectiveness can’t be guaranteed. So, it’s best to stick with TGA-registered sunscreens in Australia or those compliant with New Zealand regulations to ensure you’re getting the protection you need.

Sunscreen: A Safe Defence Against UV Damage
Some people worry about the safety of sunscreen ingredients, but when used as directed, sunscreen offers many more benefits than perceived risks. It’s important to consider that UV rays are known to cause skin cancer, sunburn and premature ageing by damaging the skin’s DNA; whereas sunscreens are highly regulated, undergo rigorous testing and must meet strict safety criteria in order to be sold. So when considering the harm that can come from the sun’s UV rays, sunscreen is a much safer choice.

Sunscreen for All Skin Tones: No Exceptions
Many people wrongly think that sunscreen is mainly for people with fair skin, but that’s not the case at all. Sunscreen is important for everyone, no matter their skin colour because skin cancer doesn’t care about your complexion – the sun’s harmful rays can hurt anyone’s skin. While it’s true that melanin, the natural pigment in our skin, does offer some level of protection, sun’s harmful UV rays still penetrate all skin tones and can cause damage. Skin cancer can affect individuals with all skin tones, and UV exposure can cause premature aging and a range of other issues. So, it’s a smart idea for everyone, no matter their skin tone, to use sunscreen every day as part of their skincare routine to stay protected.

UV Rays: They Don’t Take a Break on Cloudy Days
Many people associate sunscreen with warm, sunny days. However, the need for sun protection goes beyond clear skies and scorching summer heat. UV rays are present on gloomier days and penetrate through the clouds, causing sun damage even in the winter months. The level of UV exposure might be lower than on a sunny day, but it’s still significant enough to cause skin damage and increase the risk of skin cancer. So, don’t be fooled by the overcast sky; always apply sunscreen before heading outdoors.

Sunscreen Is Not a Magic Shield: Other Protective Measures
While sunscreen is a valuable tool in your sun protection arsenal, it shouldn’t be your sole defence because it’s sadly not a magic shield that renders you invulnerable to UV radiation. Sun can still wreak havoc for several reasons including incomplete or insufficient sunscreen coverage or forgetting to reapply. Remember to bolster your sun protection with other methods like seeking shade, wearing protective clothing (wide-brimmed hats, sunglasses, long sleeves, and pants), and limiting sun exposure during peak hours.
In conclusion, the importance of sunscreen cannot be overstated – especially in countries like New Zealand and Australia where there are disproportionately high skin cancer rates. While there are many excellent sunscreen options available, the key is to find one that suits your preferences and routine because, as the saying goes, “the best sunscreen is the one you’ll use.” If you want your products to perform double duty, check out our new Defence SPF 50. It combines 5% niacinamide to target the appearance of sun damage and SPF 50 for superior protection from the sun.
