Summer ready vitamin d promoting sunscreen, has been scientifically formulated using patented technology to let through sunlight that our body uses to product vitamin D, without compromising sun protection
All conventional broad-spectrum SPF products are designed to screen out as much of the ultraviolet radiation (UV-R) as possible to prevent sunburn, skin aging and DNA damage. Broad Spectrum SPF protection protects across both UVA & UVB light and this hasn’t changed for over 50 years.
In 2016, a study was performed to test Summer Ready Vitamin Promoting Sunscrees ability to let through some of the UVB light that our bodies use to make vitamin D against four other leading brands. The first study was performed using the protocols prescribed by the US Food and Drug Administration (FDA) to determine SPF values, and conducted by Bioscreen Testing Services, Inc. of Torrance, Calif., USA. The sunscreens that were tested were Summer Ready Vitamin D Promoting Sunscreen SPF 30, and 4 other leading brands of SPF 30 and SPF 50. All sunscreens were smeared on clear silica plates, and both UVA and UVB light from a lamp was shone through the sames and the percentages of light that passed through the plates was measured on the other side. The percentages of UVA light that passed through was consistent across all samples, however UVB light at a wavelength of between 290 nm - 300 nm (the range our body produces vitamin D) differs greatly and is shown in the bar-chart above. As is clearly outlined, there is a significant different in the percentage of UVB light that is transmitted between all the sample sunscreens, with Summer Ready Vitamin D Promoting Sunscreen across all SPF's showing a far greater transmittance of UVB light.
In another in-vitro study conducted in the laboratories of Dermatest of Sydney, Australia, they examined how this UVB exposure would impact our bodies ability to potentially produce vitamin D. Vitamin D intake is usually measured in International Units (IU’s). One MED dose (time it takes for the skin to begin to turn red) of summer mid-day sunlight exposed directly on most of the body of a middle-aged person with healthy Caucasian skin will usually result in the production of between 10,000 and 20,000 IU of vitamin D.
Based on both of these studies, we can calculate that exposing a middle-aged person with healthy Caucasian skin to One MED dose of summer mid-day sunlight, should result in the skin producing vitamin D using all of the sunscreens we sampled. However, the range of results differ significantly across the sunscreens sampled, showing that the Summer Ready Vitamin D promoting formula’s allows a larger percentage of the vitamin D forming UVB light through without risking or sacrificing the Sun Protection Factor (SPF).
A peer reviewed paper was published in the Plus One Medical Journal to demonstrate this technology.
