Step 4SPF Table
Use the following table to determine your measurements.
For example, 8oz. (weighed) of lotion + .8oz of titanium micronized dioxide (weighed) = SPF20+
The Micronized TD is 10% of the original amount of lotion used (not the finished weight).
If you used 8oz of lotion + .8oz of Micronized ZO, the SPF would be 11-12.
If it's still too confusing, ask!
