My wife has a "Dr Dennis Gross Red Light Mask" that has a setting for 650nm + 850nm red light. Supposed to help with aging or something but the specs match up perfectly.

Probably way too expensive for people to buy for this purpose(probably too expensive for skin care too, it's just a mask with red LED's, if I knew that's what she was buying I probably would've just made one. That's probably why she didn't tell me). Anyway, for anyone out there looking to buy a product, it's worth checking if your wife/gf already has something. Lots of products like this for anti aging as well as for hair growth
