Knowing that skin types and genetics play a role, but how much time in the sun is typical toxic to one's skin? i.e. What is maximum amount of time in direct sun before phototoxicity sets in?

I am from Ohio and was extremely Vitamin D deficient. Does the sunscreen and clothing just block the UV rays. Or how does the sun provide Vitamin D. When wear layered clothing does this prevent the vitamin saturation?
