After getting used to the laser at the second setting I moved up to level three (about two and a half weeks after starting).
Level three is a bit more painful. It still feels a bit like tiny pin pricks but each of the four areas are treated for around 90 seconds. This also means it now takes three times as long to use. All in all with pre cleansing treating and post serum it still only takes about ten minutes. The batteries however run down much faster on the highest level and I find myself having to charge it after every couple of treatments.
Post treatment my face now goes tomato red and I'm pretty sure I could cook eggs on my face for at least ten minutes. It does sting for a while after ... I'd definitely advise avoid touching your face too much as it makes it sorer and don't do this treatment right before bed. It takes my skin around 30-40 minutes to settle down and then still for a few hours after I look a bit too pink.
