When I first bought Lipsense I was kinda skeptical that it was expensive and I wouldn’t end up liking it. I was dead wrong. From the first time I used it I fell in love with it! I couldn’t believe how long it lasted and how I didn’t have to reapply after drinking or eating or even kissing my husband!It does slightly tingle when you first apply but it goes away after lipgloss.First time I used it, it lasted probably 5-6 hours and as my lips healed, now it lasts all day! 8 + hours!I love how you can mix colors together to get a totally different and unique color!A tube can last at least 6 months with regular use.I won’t buy any other brand lip color after trying this
