Claire, I don’t recommend you use stuff you don’t need. If you’re interested in prevention, wear sunscreen every single day. UV rays are responsible for up to 90% of premature aging, so, as simple as it sounds, wearing sunscreen every day really is the only way to seriously prevent premature aging. Everything else only makes a negligible improvement.

Hi Gio, will a little helps a long way? For example if young adults in their early 20’s started using a skin light therapy device, will it do something? Or it’s just another gimmick.

Claire, these treatments should be done only at a doctor’s office. At home devices are too weak to make much of a difference.
