SolaWave.

"This is the Solawave, which I have used and I do love for spot treating or for travel. [...] When you're using this, it only targets a very specific area, even when [...] you're rubbing it all over your face. Most LED products literally state on the package that you need to use them for 10, 15, or 20 minutes in order to see results. If you're actively moving a wand like this across the skin, you're not getting 15 to 20 minutes on every single spot on your face."

"Do you need red light therapy in your routine? The short answer is no, but it can be a nice thing to add on. Don't look to red light to solve all your skin's problems, if you're not wearing sunscreen every day, exfoliating in some manner, and using vitamin C in the morning, you're not going to see a ton of benefit from it. This is a really popular device and it's not terribly expensive, especially compared to some LED masks that cost close to five hundred dollars. I'm not big personally on using skin care devices, I don't take the time to do that regularly in my own routine, and I prefer an LED mask so I can put it on and go about another activity rather than stand in front of the mirror with a wand like this."
