Your product must be tested on human subjects in order to receive an SPF rating. It’s costly in terms of both time and money, and there’s still a chance your product won’t get the desired SPF rating. Therefore, you may need to reformulate, which will incur more costs in both time and resources.
In order to estimate their SPF level before actually paying for it, most people turn to laboratory tests. However, a trustworthy test has been lacking until recently.
A new SPF testing method is close to being approved, and it promises to greatly enhance the accuracy of forecasts. Because of this, creating new sunscreen products will be much simpler and cheaper than ever before.
The product is applied on plates made of plastic that have been handled and prepared in a particular way. They are irradiated in a safe environment. So, the tricky part is figuring out how to get the medication and conditions just right so you can anticipate the results of a large-scale experiment.
It’s still in its infancy right now, and there will inevitably be a learning curve involved with it. When the promise is released into the real world, it is possible that it will not be realised.
If successful, however, this might pave the way for smaller companies to more easily enter the market for sunscreen products.
