Sunscreen 101: The Ultimate Sunscreen Selection Guide
When it comes to protecting our skin from harmful UV rays, choosing the right sunscreen is crucial. Not only does sun protection decrease your risk of developing skin cancer, but it also prevents the signs of premature aging. Knowing that 1 in 3 cancers diagnosed worldwide is skin cancer and that people who wear SPF15+ daily show 24% less skin aging than those who don't, shows the benefits of sunscreen are crystal clear but many of us still skip out on wearing sunscreen.
With endless options available and the spreading of misinformation, selecting the right sunscreen can feel overwhelming. To help you learn everything you need to know, here is the ultimate and simple sunscreen guide so you can stay safe year-round!
- Use a Mineral Formula
Mineral sunscreens offer a reliable and safe option for shielding your skin from the sun's rays. These formulas are made from 2 active ingredients: titanium dioxide, zinc oxide, or a combination of both. It creates a physical barrier that reflects and blocks UV radiation. Unlike chemical sunscreens that absorb UV rays, mineral sunscreens provide immediate protection upon application. They are particularly beneficial for individuals with sensitive skin as they are less likely to cause irritation or allergies. For those reasons, we recommend always opting for a mineral formula for a safer and reliable sunscreen.
- Wear a Minimum of SPF 30
The Sun Protection Factor (SPF) indicates the level of protection a sunscreen offers against UVB rays, which are primarily responsible for sunburn. It is crucial to choose a sunscreen with an SPF rating of 30 or higher. SPF 30 blocks approximately 97% of the sun's UV rays, while SPF 50 provides a slightly higher protection rate of around 98%. Selecting a sunscreen with SPF below 30 will provide minimal and potentially ineffective protection. To safeguard your skin adequately, opt for SPF 30 or higher.
- Check the Active Ingredient Percentage:
While SPF is essential, the percentage of active ingredients in sunscreen plays a vital role in determining its effectiveness. While most believe a minimum of 10% of either zinc oxide or titanium dioxide is enough, it is even better to choose a formula with a higher concentration, preferably between 17% and 25%. This ensures enhanced protection against both UVA and UVB rays. It's worth noting that you won't find sunscreens with active ingredient percentages exceeding 25% as they are deemed unsafe for topical use.
- Avoid Sunscreens that are "Waterproof" or "Sweat Proof"
It's important to be cautious when evaluating sunscreen labels. Claims such as "waterproof" or "sweat-proof" are not validated by regulatory authorities and can be misleading. Instead, opt for sunscreens labeled as "water resistant," as they are designed to maintain their efficacy for a specific duration after water exposure. Keep in mind that even water-resistant sunscreens require reapplication after swimming or engaging in sweaty activities so remember to RE-APPLY!
Keep this check-list handy the next time you're on the hunt for your perfect sunscreen:
- Mineral sunscreen
- SPF 30 or higher
- Active ingredients between 17% and 25%
- Avoid "waterproof" or "sweatproof" sunscreens
- Check the expiration date - do not use expired sunscreen, it will not work!
By following these guidelines, you're sure to find a safe, reliable and effective sunscreen that will keep your skin healthy!
