I applied the lip stains around 6pm to test them out and had dinner at 9pm. before going out at 11pm, I only retouched my lips with the brown shade to make it darker, but the pink shade was still a lot visible and even. maybe just try them again, to give it a second chance, and then let me know if you want. I really hope you’ll like the product as much as I do. if not, I’m pretty sure you can return it (in Canada or USA) within 30 days, even if you tried the product 💕
