I am using it directly on my skin, so it can only be used for 15 minutes. There is a built in 15 minute safely timer, it switches off the device. If you require a longer time just turn it on again Now this is the first time Im using the Lumie Clear. It feels warm against my cheek but nothing more. Im having to use it in sections to be able to completely covering all the affected areas. All together to cover my chin & cheeks ares it takes an hour, daily.
So please bear with me, I will show you results weekly.
Please note I have been given the Lumie Clear to test.
