With its stunning color and plumping effect, this is a surefire birthday gift for yourself, and a must-have! I love the exquisite color variation and the blissful finish you feel the moment you apply it. I use it myself, and when I'm unsure of what to give as a birthday gift to a friend, this is my first choice. Honest review: The colors are so exquisite and cute you'll want to collect them all. Each shade blends well with the skin, yet instantly brightens the complexion, making them so cute. Even the selection process is exciting. A pleasant plumping effect creates the perfect lips. With a gentle, refreshing feeling, it reduces vertical lines and plumps the lips. Packed with serum ingredients, it's truly décolleté-quality, allowing you to care for your lips while applying makeup. It makes a perfect gift—a special touch. The luxurious packaging, affordable price, and perfect balance of practicality and cuteness make it a great choice for gifting, as it will delight the recipient the moment they receive it. [Overall Review] A great gift for yourself or someone special. This is a gift cosmetic that has earned a place in my hall of fame, as it is a gift that I give to friends who love cosmetics and they always compliment me on my taste.
It's a mature color. I'm a warm spring skin tone, and I use it when I want to add depth to my makeup. I don't know if it has a plumping effect, but the color payoff is impressive. It lays down well with just one application. It doesn't sting, but rather has a cooling sensation. However, since it's positioned as a lip serum, I wish it was a little more moisturizing, and while the hard tip is nice, it's thick and makes it difficult to apply to the edges of the lips. It also has a fragrance, and a strong taste when it gets in your mouth. However, the gloss is elegant, so I think it would be a versatile product to keep in your purse.
There was a time when they overlapped, but I used them in the order 04, 02, and 03, and I'm currently using 03. 04 is a limited edition color and I don't think it's available anymore. There was a time when I used 02 every day. 03 has the strongest tingling sensation, but they all seem to have the same plumping effect. 03 is the most pigmented, so I only need that when I go out. The plum color is perfect for this time of year and is my recent favorite. The moisturizing effect lasts a long time, which is great.
This is my favorite lip product. I use it to moisturize my lips. This is my second purchase. It doesn't sting and leaves my lips plump, so I love it!
