As the summer months approach, one of the most important items to pack for a day out in the sun is sunscreen. Sunscreen not only protects us from painful sunburns but also plays an essential role in preventing skin cancer.
According to the Skin Cancer Foundation, skin cancer is the most common type of cancer worldwide, and exposure to UV radiation from the sun or tanning beds is a significant risk factor. But with so many types and brands of sunscreen available on store shelves, how do we know which one to choose?
Firstly, it’s crucial to understand what SPF means. SPF stands for Sun Protection Factor and measures how well a sunscreen will protect our skin from UVB rays. The higher the SPF number, the more protection it offers against harmful UVB rays that cause sunburns and can lead to skin damage over time.
However, it’s essential not just to focus on high SPFs alone but also on broad-spectrum coverage that shields us from both UVA and UVB rays. UVA rays penetrate deep into our skin layers causing premature aging while contributing significantly to skin cancers’ development.
Secondly, consider your unique needs when choosing a sunscreen product. For instance; if you have sensitive skin or allergies prone-skin, look for hypoallergenic or fragrance-free options that are less likely to irritate your skin. If you’re going swimming or sweating excessively during outdoor activities like sports events or beach days – opt for waterproof varieties designed specifically for these situations.
It’s worth noting that there has been some concern over certain chemicals commonly found in some sunscreens such as oxybenzone and octinoxate being potentially harmful when absorbed by coral reefs leading Hawaii banning their use in 2018(1). However right now scientific evidence is limited.(2)
Another consideration when selecting a sunscreen brand is its application method – spray versus lotion form- which depends largely on personal preference with pros and cons associated with each. Sprays are convenient and easy to apply, particularly on children or hard-to-reach areas like the back of your neck. However, it’s essential to ensure that you spray enough product for full coverage while avoiding inhaling the mist. Lotion sunscreens may take longer to apply but can provide more consistent coverage with less risk of inhalation.
When it comes to application quantity, experts recommend using at least one ounce (approximately a shot glass) of sunscreen for each application(3). Apply generously all over your body 15-30 minutes before going outside and reapply every two hours or immediately after swimming/ sweating heavily as even waterproof sunscreens will eventually wash off.
Finally, don’t forget about other protective measures beyond just sunscreen alone; seek shade during peak UV hours between 10 am and 2 pm when the UV radiation is strongest; wear protective clothing such as long sleeves and wide-brimmed hats which can help shield skin from direct sunlight.
In conclusion, incorporating sunscreen into our daily routines is an essential component in preventing skin cancer and maintaining healthy glowing skin – be sure you’re using the right type for your needs by looking at SPF levels, broad-spectrum coverage options, personal preference around application methods – lotion versus sprays -and specific environmental considerations including sensitivity issues , water-resistance requirements or eco-friendliness concerns . Remember that wearing sunscreen alone isn’t enough; always seek out shaded areas during high-risk times of day and cover up when possible with appropriate clothing choices!
