And so I think people haven't found the right frog and they've kissed many frogs, but they haven't found the right one.
What SPF should you wear every day?
It's a great question.
SPF is more than just a number.
So SPF stands for sun protection factor, but it measures basically how well your skin is protected.
So when we're looking for an SPF, we need to make sure that our SPF has broad spectrum on it.
So that it's protecting against both UVA and UVB because both contribute to skin cancer.
One causes more burn like UVB.
One contributes more to the breakdown of your collagen like UVA.
But if you're just getting a simple sunscreen, SPF, not broad spectrum, you're not protecting against UVA.
So broad spectrum is not a nice to have.
It's a need to have.
Okay.
Okay.
That's number one.
The second thing, SPF 30.
People don't really know.
It's just a number.
Should I guess what I think it is?
Yes.
