How do I keep misty rainbow skin? It keeps giving me the same star chaser.

Hello @TexasGlock76 and Welcome to our Divine Candy Crush Friends Community! 😁

For some players this is normal as you will receive 3 1 day duration star chaser events for 9 stars each. Other players may receive a 3 day duration star chaser event for 27 stars (this was what I received). 🤔

This is simply an event that awards you with stickers and sweet boosters upon completion. You don't have to worry about losing any of your previously gained costumes! 😄

I hope this information helps you understand this event better, and I hope you have a crushtastic day! 😆
