Physical vs Chemical Sunscreen - Reapply or not?

Many people focus on “no whitecast” when choosing sunscreen, but it's also important to understand the type of sunscreen you're using—especially for reapplication! ☀️Physical Sunscreen (Mineral) Main ingredients: Zinc Oxide, Titanium Dioxide 🧪How it works: Sits on top of the skin and reflects UV rays ▫️Whitecast? Yes, more likely. A lot of people avoid physical sunscreen because of the whitecast—but thanks to newer technology (better formulations), some physical sunscreens no longer leave a strong whitecast. However, they can still feel thicker or heavier on the skin, since they sit on the surface rather than absorbing in. That’s just how physical sunscreen works! Reapplication: Ideal if you're sweating or exposed to strong sun (like beach/outdoor activities). Unless if you are indoors or mild weather, no need to reapply, just once in the morning routine. ☀️Chemical Sunscreen 🧪Main ingredients: Avobenzone, oxybenzone How it works: Absorbs UV rays and converts them into heat ▫️Whitecast? Usually no whitecast and feels lighter on the skin Reapplication: A must, especially after sweating or every 2-3 hours if under the sun 💡Even if your sunscreen has no whitecast, always check the ingredients to know what type it is—this helps you know how and when to reapply!
