Solving the problem of color loss in products
<font style=”vertical-align: inherit;”><font style=”vertical-align: inherit;”>in my herbal shower gel formula there is a dye used, whether I tried natural or synthetic dyes it still loses color when exposed to natural light. I am having a headache wondering if it is photolysis or oxidation or is there any other reason? I really hope to get help?</font></font>

If it happens right away, then UV is not to blame; but if it happens gradually or only in a UV chamber and your package is transparent, then you need a UV filter.

In my opinion, when I use natural colors, when exposed to UV rays, it stimulates the energy of the molecules, leading to the breaking of double bonds, causing color change. So do you think there is a way to solve it from the solution itself?
