Most skincare tools promise to do a whole lot. Need to zap zits? There’s a tool for that. Sculpt sagging skin? There are a couple of devices for that, too. Reduce dark spots? Yes, a gadget can help. The technology is so advanced these days that there are numerous options that claim to target the signs of aging like fine lines and wrinkles. Some are self-proclaimed better alternatives to in-office procedures like Botox injections.

But I know you’re probably wondering, Do they really work? Valid question, especially since a lot of these devices aren’t exactly the cheapest. Well, first, no tool or beauty product can really give you brand-new skin entirely, but there are a lot of effective devices out there that can get you pretty dang close.

To help you shop smarter (and not waste your money on something completely worthless), take a look at some highly rated gadgets and editor-favorite devices that have some pretty incredible results below.
