Comment on Matcha green tea face mask by Norys.

Hi. I tried this and it’s amazing. I do have however a few questions:
1. How should I store the leftover so it doesn’t turn black?
2. Do I need to heat up the coconot oil so it becomes liquid or can I use it as a paste? Last time I used the paste but was not sure about ratios.
Thanks in advance!
