Several lab technicians almost quit their jobs before Ji was satisfied with the nail polish that would bear the Rescue name. The result is a long-wearing nail polish (in the most fashionable colors EVER) created with resin and high molecular polymers to improve flexibility, durability and high shine. What you won't find - harmful and drying Touluene, Formaldehyde, or DBP. Seriously, it took two teary years...
Fantastic color range, Grunge and Cherry Love are my absolute favorites. Grunge is a super cool opaque beige with a cool gray/lavender undertone--it literally launched the whole griege nail polish trend that we've seen over the past couple of years (Grunge came out first)!
I admit, they have an AMAZING color range which is why I've gone to them so many times in hope that the next bottle will not expire so quickly. But no, it thickens and dries up within just a few months. I like to buy just 1 shade during spring then use that polish as much as I can during that time to hopefully past summer, so at least it'll be sort of worth the heavy price tag.
