I bought one of these ages ago and have been too lazy / disorganised to use it even once. I have recently resolved to take better care of my skin and dug out the mask. It is lovely! Too early to say whether it has any meaningful effect on the appearance of my skin, but the actual ritual of lying with the mask on is so soothing. I have since read that red light rays are good for your mood and I honestly think it works. I have been having real challenges with low moods recently (likely peri) and this really seems to make a difference. I am doing it every night at bedtime. Just wanted to share!
