Think of sunscreen as your skin’s bouncer, not its party pooper. It filters out the harshest UV rays, especially the nasty UVB ones that cause burns, while letting in some of the gentler UVA rays that trigger melanin production. Melanin is your body’s built-in bronzer, and sunscreen just tells it to take its time and work safely.

In other words: you’re not blocking the tan—you’re coaching it. Your skin will still darken, just at a slower, healthier pace. And honestly, who wants a fast tan that peels off in a week? Speak directly to me—a slow, steady tan is the one that actually lasts.

What About SPF 50 or 100? Does That Stop Everything?

Here’s where the myth crumbles. No SPF blocks 100% of UV rays. SPF 50 blocks about 98% of UVB rays—that still leaves 2% sneaking through to trigger a tan. SPF 100 blocks 99%, so a mere 1% gets through. That tiny sliver of UV is enough to stimulate melanin, especially if you’re out there for a few hours. It’s like a slow-cooker for a tan, not a microwave.

So yes, you’ll still get color—just without the lobster look. And you’ll skip the sunburn pain that ruins your weekend. Win-win, right?
