This is a great question, there is a lot of confusion about silicones and misunderstanding that they are all harmful. While we do have silicones in our ingredients, they are the safe “green” variety that are non-cyclic, which has been verified by the evaluation of our formula by the Environmental Working Group (EWG). We have been dedicated from the beginning to providing the most effective sunscreen possible while also making sure that it is not only safe for the environment but safe for skin of all types and ages.
