I know.
We've come a long way.
The number one thing people are getting wrong is how much sunscreen they're applying.
I feel like the average person vastly underapplies their sunscreen.
So they're not really getting the protection that they think they should be.
What is the right amount to apply?
So it's a little bit of an estimate, but we want people using about a quarter teaspoon for their face and ears.
So for a lot of people, that's going to be about two finger lengths on their hand, because when they're assessing the SPF or the sun protection factor of a sunscreen, they're really counting on you using the correct amount.
And if you're under applying it, you're not getting that SPF 50 or that SPF 30 that's stated on the bottle.
No, it's not.
It's a little bit of a nuanced answer, but the reality is most people, including dermatologists, do not reapply throughout the day.
And if you are mostly indoors and you're not having tons of sun exposure, reapplication becomes truly less important.
But if you are out with lots of UV exposure and you're not wearing a hat, I would prefer you to reapply every couple of hours because exactly as you said, the sunscreen breaks up on your face, you get patchy coverage.
That doesn't mean it becomes completely ineffective, but it becomes less protective over time.
For all of those things.
And I always tell my patients, protect your investment.
If you're getting laser procedures, if you're using actives, there are even studies that show that if you just wear sunscreen and use no actives, it actually reduces your photo age.
So it reduces...
Wait, it doesn't just prevent it?
No, there's reversal.
