Can you really trust home beauty devices?

I recently purchased a new beauty device, but I keep wondering if it is as effective as advertised. In particular, it is difficult to establish a usage rhythm because it is unclear whether I need to use it every day or just a few times a week. I am also concerned that irritation might accumulate on my skin when using the device, and I wonder if it might actually hinder the absorption of ingredients when used alongside other skincare products. Given the price, it is difficult to judge whether this device will truly be beneficial or detrimental in the long run. Furthermore, since I use it alone at home, I am unsure if I have fully mastered how to use it. As a result, lately I have been debating whether to continue using this device, switch to a different one, or even stop using it altogether. Please help me.
