I’m currently using epiduo to treat acne, which makes skin more likely to burn. The only sunscreen that I’ve ever found that doesn’t give me hideous acne is the bare minerals natural sunscreen power, which they’ve discontinued 
I tried to rely on the spf in my makeup yesterday and my face felt a little sore in the evening, so I need a proper sunscreen.
The La Roche-Posay Anthelios Sun Protection Face Mist looks good, but the main ingredient is butane, which is a known carcinogen (said to cause skin cancer?). Surely this is what I want to avoid!
My pores are so enlarged that anything sitting on my skin blocks it and gives me spots.
Any recommendations?
