ABOUT SOLAR D

Vitamin D promoting technology

The unique patented formulation of Solar D sunscreens permits the passage of some of the wavelengths in the vitamin D forming range, about 290 to 310 nm while effectively filtering the unwanted, harmful wavelengths, about 315 to 380 nm.

Solar D Sunscreen Studies

The objective in formulation Solar D sunscreens was to permit the passage (marked in the graphs below as “Pass”) of some of the wavelengths in the vitamin D forming range, about 290 to 310 nm while effectively filtering (“Filter”) the unwanted, harmful wavelengths, about 315 to 380 nm.

Sunscreens were applied to plates and light was shinned through them. A detector at the other end recorded what percentage of light was permitted to pass (i.e. was transmitted) for various wavelengths of light.

What was found was that there are four major groups of sunscreens, categorized as follows:

A.) Sunscreen products which permit the passage of some of the sunlight our skin uses to produce vitamin D, and effectively filter unwanted, harmful UV rays (see “Pass, Filter”), Solar D sunscreens are in this category, (dashed orange lines in figure below),

B.) Sunscreen products which effectively filter the sunlight our skin uses to produce vitamin D, and more or less effectively filter unwanted harmful UV rays (see “Filter, Filter”),

C.) Sunscreen products which permit the passage of some of the sunlight our skin uses to produce vitamin D, but do not effectively filter unwanted, harmful UV rays (see “Pass, Pass”), and

D.) Sunscreen products which effectively filter the sunlight our skin uses to produce vitamin D, and do not effectively filter unwanted, harmful UV rays (see “Filter, Pass”).

The “Pass, Filter” is Solar D SPF 30 Spray (dashed orange line).
