Testing one product to another

I want to try out Acneticin after I will be finish using this acne treatment that I have right now. I just want to do some experiment and see what acne treatment that is good for my skin. It will be like my slimming thing that I am testing from one product to another. And right after figuring out a particular brand that surely is effective, it will be the best time for me to stop searching and then use the brand of choice all throughout my journey of my beauty regimen.
