Home care devices: Are there any products that you won't regret spending a lot of money on?

These days, social media ads for home care beauty devices like LED masks, galvanic devices, and EMS devices are so tempting. They advertise that buying one will literally save you from having to go to the dermatologist, but I'm hesitant to make the purchase for fear that I'll just use it for a few days and then throw it away in a drawer. If you have any recommendations for devices that you think are "worth the money" or "overcome my laziness and use every day," please let me know! I'm on the verge of a spending spree, so I need your honest reviews. Whether you like cost-effective products or expensive options, please share your thoughts!
