I have used these lipsticks regularly for about a year and found them to be quite good at staying put, but still found that they lasted only a few hours. They were however at the time the best lipsticks around.
There are lots of lovely colours and they are very soft on your lips and stop them from cracking. The packaging is nice and simple, although the colour sticker on the bottom fades, so it becomes difficult to tell the colours apart in a makeup bag.
I have now discovered Lipfinity from Max Factor which has 10 times the staying power and is only £1 more, so unless Oil of Olay can improve on their formula, I'm afraid I've now had better.
