IOPE Products

I recently bought the IOPE Expert Retinol 1%. I switched from prescription Retinal because my skin didn’t get used to it even after months of use. The IOPE retinol seems to be working better, but it's too soon to tell. They also sent me trial sets of the IOPE XMD Stem III Clinical Recovery and Super Vital products. I'm not sure if I should be testing them as well. Has anyone used that brand before? I don’t think this brand is very popular because I can't find much online.
