Founders' Note
From Meg & Eli
We started SONNI because we couldn’t find suncare that fit into our real life – something that made as much sense in a beach bag as it did on a desk. With melanoma in both of our families, the need for better suncare became even more urgent. Now, SONNI has become the habit we don’t think twice about. Can't wait for you to try!
