This device is very similar to LightStim, but you don't have to plug it in. You can recharge it after you use it for a few times, which is great for those who don't want to worry about a cord. I dig this device, but it definitely takes a lot more time than the others. The brand's treatment advice is to use both the blue and the red light for three minutes each on each section. Since I have four sections I consider problematic, this means 24 minutes of downtime, compared to 12. For those in a rush, it can be a bit time-consuming to complete the recommended daily treatment. Does it still work? Definitely! And the paired free mobile app keeps you accountable.
Though not technically intended for acne, Eterno definitely helps reduce redness and creates smoother skin. Believe it or not, Eterno uses the same technology that NASA uses to grow plants in space. Yep, so just think what that does to your pores! Treatment time with this one is longer—10 minutes for each area—but it is said to boost collagen and reveal prettier pores. My mom has been using this one—and has basically fallen in love.
