I got a gel liner from Nyx, which came with a box explaining it’s usage, and something I never thought about before: storing the gel liners ***upside down*** in a dark, dry drawer. I’ve always thrown them in my drawer right side up, which may have contributed to them drying up and cracking earlier than expected. Maybe the moisturizing ingredients settle into the bottom of the jar? After reading that, I turned my gel liners upside down. Time will tell if they last a bit longer than expected.
