What is this method? I haven't heard of it. Can you explain more please?

I mix tea tree oil with jojoba oil and rub all over my face then wash my face twice with a cleanser

I've just started this method and i already see a huge difference. you basically wash your face twice. Once to remove all the moisturizer, sunscreen and makeup and a second time to remove dirt and impurities. I use a cleansing lotion( You can use a oil cleanser, cleansing milks or lotions, etc) and i rinse it and use a soft face cloth to make sure all my moisturizer and makeup is off, and then i use a gel cleanser and repeat the same process and use my night products on afterwards. You should only do it at night. This method helps your products absorb better and you get a deeper clean.
