Can anyone share their Isntree create together experience?

Is there anyone who would be willing to share their experience with the Isntree create together project? 🙂 For those who joined Picky later, it was an Isntree "giveaway" for SPS members about half a year ago. The winners were involved in the creation of Chestnut BHA liquid. I'm very curious how the participation looked like. 🙂 Was it only testing before release, or did you have some say about the ingredients etc.? Would you please share your experience if you've won this giveaway? Thank you! 😊
