The Advantages of In-Vitro Testing with Solar Light

In-Vitro testing is testing that is performed on a non-living medium or substrate. At Solar Light, we are providing our in-vitro SPF testing instruments and devices to laboratories and industries manufacturing items that are typically used for sun protection. We are also market leaders in in-vivo SPF testing equipment, which uses live panelists as a substrate for the tests. Solar Light is the only company providing the complete range of equipment required for both in vitro and in vivo SPF and Sunscreen testing in the world.

Our solar simulators, SPF analyzers, spectral scanners, and every other instrument and tools we use for testing, measurement and quantification are optimized for in-vitro and in vitro SPF testing.  These tools greatly reduce research times during the formulation and product development testing phases.

Many of our clientele use our products during the development and formulation stages.

Here are the reasons they do:

For one, in-vivo testing processes obviously require living subjects. These test subjects require extensive consultation, as well as in-depth informed consent before the testing can proceed.  During the testing process, the administrators are responsible for the safety and health of these subjects, and if any complications occur, the billing falls to their organization.

In-vitro testing instruments and devices can reduce research and development costs by eliminating living subjects from certain parts of the development process.

Photobiologists have a duty to their patients and research participants to protect their well-being while pursuing information and education. The FDA defines photobiology as “the study of the effect of UVA and/or UVB, visible and IR radiation upon living systems.”  In order for these studies to be effective and accurate, scientists must only use the highest level of technology and research standards. Solar Light effectively produces devices that provide just that.

Photobiological researchers work tirelessly to determine the potential photoirritation and potential photoallergenic responses to cosmetics, medications, SPF products and more. Photoallergy is defined as an “acquired, immunologically-mediated reaction to a chemical activated by light.”  Photobiologists must effectively determine when and where these reactions will occur.

Likewise, photoirritation is a “light-induced, nonimmunologic skin response to a photoreactive chemical.” Solar researchers are always working to predict the varying levels of photoirritation to expect from any given cosmetic, medication or any other product.

It’s clear to see that Photobiologists and other solar radiation specialists face many obstacles when producing, researching and developing products in our industry. That is why at Solar Light we strive to produce instruments, tools and devices that improve and enhance the research and development processes for companies that bring cosmetics, medicines, sun protection products and more to the end-user.
