Frequently Asked Questions
What is the core difference between a mineral sunscreen and a chemical sunscreen?
A mineral sunscreen (also known as a physical shield) uses natural mineral active ingredients like zinc oxide or titanium dioxide to sit visibly on top of your skin, deflecting UV rays away like a mirror. A chemical sunscreen absorbs seamlessly into your skin layers, converting UV light into harmless heat. Mineral options are frequently recommended for ultra-sensitive skin or as reef-safe selections.
What does the SPF level mean for my UV defense?
SPF stands for Sun Protection Factor, and it primarily measures defense against burning UVB rays. An SPF 15 formula filters roughly 93% of UVB light, SPF 30 filters roughly 97%, and a high-performance choice like an SPF 50 option filters roughly 98%. Dermatologists universally suggest using a baseline of SPF 30 or higher for daily outdoor exposures.
How often should I reapply sunscreen during pool or beach days?
For standard outdoor tasks, you should reapply your sunscreen every two hours. However, if you are actively swimming or sweating, the protection wears away faster. Even when using water-resistant or waterproof formulas, it is highly recommended to reapply fresh sunscreen immediately after drying off with a towel.
At what age can you start applying sunscreen to infants safely?
According to standard guidelines, you can safely apply targeted sunscreen options to infants once they reach six months of age. For newborns under six months old, pediatricians suggest prioritizing physical shade structures, strollers, wide-brimmed hats, and protective clothes to manage sun exposure naturally rather than relying on topical sunscreens.
