This tool is on the way
The Sunscreen Amount Calculator is catalogued and being built. It targets the question “how much sunscreen to apply” — and like every SkinSorted tool, it will answer it with numbers and cited sources rather than a wall of text.
In the meantime, the related tools below cover neighbouring questions. The full catalog lives on the tools index.
