Hi there - going well with it - the start-up guide in the kit is rather over-cautious. They suggest a 2 week conditioning period with sessions of only a few seconds. Well my lips must be pretty tough, as I'm doing 3 min sessions after 1 week - almost doubles the size of your lips (although it deflates after an hour). No bruising or pain - in fact they seem healthier. I've always had pale lips that go blue in the cold very easily, and since I started with the lip pump they are much more red and tingly. The shape seems more defined too - and the lip pump centers most of the pull in the centre, so it gives a 'pouty' effect rather than just enlarging the lips all over.
It's not something that will give you permanently enormous lips in the first week, but I'm approaching it just like the NB system - something that works in the long term, just fit it into your routine and don't track your progress too obsessively - patience pays off in the end!
