Aeroblend makeup line does not have an SPF rating, however, you may certainly apply a sunscreen moisturizer on your skin prior to airbrushing.
You may use your favorite sunscreen as long as it is fully absorbed into your skin prior to airbrushing.
If you need a sunscreen recommendation to use with Aeroblend, we like Josie Maran's Argan Daily Moisturizer Mineral SPF 47.
