This is my first experience with Karine Joncas line and, I must say, I'm blown away at the effectiveness of this serum. Two light pumps is more than plenty for the whole face, neck and décolleté. I use it after washing my face for the night and, in the morning, I wake up with a huge improvement - my face is smooth and taut, especially around outer corners of the eyes, and smile lines. Also, my neck looks younger now. The effects of this serum are like having botox, but without the needles. I have tried a plethora of serums in the past, cheaper ones as well as the ones you need to take a small mortgage for but this Karine Joncas serum put them all to shame... and the bin as there is no point of wasting time on ineffective serums when you're in your sixties, or any age for that matter.
