Sunday Skin makes a sunscreen that does not feel like sunscreen. We turned a boring daily habit into a running joke between the brand and its audience, and the product kept selling out.
[01]
The low pressure
Everyone agrees SPF matters and nobody wants to hear about it again. The category is full of white-coat lectures, and Sunday Skin's posts were getting saved but never shared.

The hunch we backed
We built a character called The Forgetter, a recurring sketch about every excuse for skipping sunscreen, and paired it with a daily 8am reminder post people could send to the friend who always burns. Dermatologists came in once a month to answer real questions in the comments.

“Our audience now reminds each other to wear SPF. We basically outsourced the nagging, and it works.”
