Do you usually apply sunscreen to your arms and legs as well?

I always try to apply it to my face and neck.

I find it a hassle to work on my arms and legs, so I don't end up doing them.

As a result, I have freckles on my arms too.

Do you apply it diligently to your arms and legs as well? I tend to wear long pants, so I don't really need to worry about my legs.

When I look at the blemishes on my arms, I wonder if I should apply something, but I find myself never actually doing it.

Will my arms get wrinkled later?
