Around the holidays, there was only one thing I bought for my mom, my mother-in-law, and my aunts, and that was the Laneige Lip Mask. Beloved by Sydney Sweeney, Porsha Williams, Alix Earle, Justine Skye, Paige DeSorbo, Hannah Brown, Kenzie Ziegler, Dr. Nicole Martin, Alexia Nepola, Drew Sidora, Delilah Belle Hamlin, Serayah, and Ashley Haas, I agreed with these celebs that it felt smooth and luxurious on my lips and left them feeling soft in the morning.
