SPF stands for Sun Protection Factor.
A product's SPF number is calculated by dividing the time it takes for skin to burn without sunscreen by the time it takes to burn wearing that specific sunscreen.
The higher the number, the better your protection; however, studies have shown that going higher than SPF 50 does not elicit extra protection but, in fact, can contribute to irritation and sensitivity.
🌞It's not a 'one and done' application.🌞
It doesn't matter how high the SPF rating is, you need to re-apply regularly in order to maintain that protection throughout your activities. A low SPF applied properly is better than a high SPF applied incorrectly.
🏊♀️NO sunscreen is waterproof.🌊
After bouts of heavy sweating or swimming, sunscreen should be applied as if it had never been worn at all.
💻Lots of screen time? You need SPF for this, too! 📲
Broad Spectrum SPF protects us from two types of harmful UV rays: UVA and UVB. UVA rays have a longer wavelength and are responsible for skin aging over time. UVB rays have a shorter wavelength and are responsible for sunburn and, ultimately, contribute to skin cancer. Wearing SPF indoors will help prevent absorption of these harmful rays through windows and from older types of screens.
🔄That burn from 5 years ago is still surfacing.⏳
Sun damage is cumulative and can take years to reach the surface as hyperpigmentation. It can make sun damage deceiving; you had a terrible burn last year but have little sun damage from it. It can be difficult to justify needing sunscreen - until it is too late. Wear SPF now for lighter, brighter skin and lower risk of cancer over the next several decades.
👄👂🤕 🤗 Remember your lips, ears, neck, head, and hands. 👏🏻😎
These are areas that we frequently miss upon SPF application but receive a great deal of sun exposure. Particularly the tops of bald heads and the back of our necks and hands when driving. Don't forget your head, ears and neck if you skip the hat, as these are the most exposed. Carrying an SPF lip balm is excellent as we often wash our SPF off when eating, drinking, speaking, and licking our lips.
