Beauty Devices

At-home beauty devices are tools, not a required step. Different technologies do different jobs — and none of them replace cleanser, moisturizer, and sunscreen.

Beauty devices are becoming a bigger part of at-home skincare, but different technologies work in very different ways. Explore the basics behind microcurrent, EMS, RF, electroporation, LED, and multifunction devices — and learn how to evaluate them before adding one to your routine.

This hub is for technology literacy and buying context. It is not a clinic, not a ranked “best devices” list, and not a product catalog.
