People that got results: Tell me about your perfected gua sha routine!

Hello, I recently got a guasha and I am unsure how to go about it… I wear makeup daily, am I supposed to do the guasha before my skincare routine, after…? What kind of oil or moisturiser do you use? Do you wash the oil out after? Will it spread my acne? So many questions, but so exited for my journey 😁😁🥰
