Recently, my lips have been shrinking and vertical lines have become more noticeable. I've been using plumpers from other companies, but I didn't feel they were particularly effective, so I saw this one in the store and decided to try it. The blue was a limited edition and seemed to have a translucent finish, but I went for the safe pink. Overall, I'm glad I bought it! It instantly moisturizes the dryness that occurs this time of year and reduces vertical lines. I also feel like the cooling sensation is a little strong. I accidentally got some in my mouth, and it left a tingling sensation for about five minutes. I think the plumping effect is better with this on than without. I apply this to my lips after completing my base makeup. Then I start applying eye makeup and blush. During this time, my lips will plump up, so I lightly wipe it off with a tissue before applying lipstick or tint. If too much of this is left on my lips, lipstick or tint won't stick. For me, this plumped up better than other products I'd used before, so I'm pleased. I'd like to buy it again. Although I have a good impression, I still want to try other companies' products, so I gave it minus 1 star.
