Vitamin D deficient. I appreciate your adoption of sun protection given you fair skin completion. All you need is 15 minutes a day which is not much sun exposure. You don't need to "lay out" to get this. This is absorbed through exposed head, neck, and arm skin. Do you know if you are Vitamin D deficient? I would not obsess over sun avoidance and your vitamin D. If you are low on testing, take a supplement.
