Having used red light therapy for years, I can say with certainty that it works. So far, that's the only mode I've used this mask in, but there are a plethora of other options! This mask is different in that it is hard plastic, rather than a form fitting foam-ish material. I don't know that one is any better than the other, just a matter of personal preference. It arrived with eye shields in place to guard against over-exposure. In some other masks, they need to be placed in by the user. Ten minutes a day, 3-4 times per week, easiest to use while lying down, but can be worn while doing household chores, and the red light function while absolutely tighten skin. Depending on the individual, results will be noticeable in 4-8 weeks. This is for sure the most affordable such mask I've seen. It's rechargeable, convenient and it works!
