’all-in-one’ products which are both pleasurable to use and show immediate results

Of course, it all depends on the products in question - Marie, more context please!!
I’m guessing that it might be cosmetics with added health benefits, and on that basis I would analyse:

spürbar = have a real effect (immediately?), you notice a difference when you use the product (skin becomes less puffy, for example), show a real improvement

erlebbar – pleasurable to use, appeals to the senses, perhaps nice smell/texture/taste

hope it helps
