This is my second one. I've used plumpers from budget brands and Korean cosmetics before, but MAC was my first department store plumper. I was surprised by the strong tingling sensation I felt when I had the product touched up in-store, but the pain didn't last that long and I didn't notice much of a plumping effect. However, my lips looked much healthier, so I bought it. I also like that it moisturizes well without feeling heavy. I bought it last April and used it as a primer before applying my morning lip color. It lasted about 10 months, so I think it's great value for money. It pairs well with any lipstick, and doesn't get in the way of tints or matte lipsticks applied on top. Applying it in the morning keeps my lips moisturized until lunchtime.
