How often should I message my ears? And how roughly how much jojoba oil would I need to reach 00g?

Hey hey, I ordered a glass dead stretching kit and I'm waiting for it to arrive! And well, in the meanwhile I've been searching for jojoba oil to buy for the stretching, and I kinda got lost, I genuinely don't know how many ml's of oil should I get! And if anyone could, it'd be very helpful to get a guide on how much, how long, and how often I should massage my ears with it, so many tutorials on how to stretch the ears, but so little on how to take care of them.. thank you all in advance 🙏
