How rigorous do you really need to be with sunscreen?

The answer depends on your exposure level, daily activities, skin goals, and personal risk tolerance.

In this video, we break down:

When you should be especially diligent about sunscreen
High-exposure situations like hiking, swimming, and paddleboarding
Why everyday indoor exposure is a little more nuanced
Why you don't need to burn to accumulate UV damage
Why sunscreen matters even more when treating hyperpigmentation or using strong actives

The biggest takeaway: the amount of sunscreen rigor you need depends on what you're actually doing and what you're trying to protect your skin from.

And if you're spending a lot of time outdoors in high-exposure conditions, don't take chances—more sunscreen and more frequent reapplication is the way to go.
