Thanks so so much Jonathan !!
I did a lot looking into this question last summer, and here's what I found out. Just like everything else about lupus, it seems to depend on which sunscreen is good for your type of skin. A lot of my friends had very strong opinions about zinc vs. chemical, but when I spoke to them about their choice, it turned out that all of them had skin allergies to some of the chemicals in sunscreen, and zinc sunscreen tends to be very clean in terms of it's ingredients, and good for their skin. When I asked my nephrologist, my rheumatologist, and my oncologist, all of them said the same thing: the best 50 UPF sunscreen is the one you will wear. My oncologist said that none of the sunscreens on the market cause cancer. So, I have both. When I have the time to rub the lotion in, I'll wear the zinc oxide. When I'm in a hurry and need to cover my face and arms and get out the door, I have chemical sunscreen that goes on very well and dries fast.
For lupus and CLE, the most important factors in choosing a sunscreen are:
- SPF of 70 or higher
- Broad spectrum protection that blocks both UVA and UVB rays
- Water-resistant formula
- Reapplication every 1-2 hours when in sun
- Application 20 minutes before sun exposure
