The product I am using is the Face Factory Ceramic Gua Sha.
I usually use it after applying oil following a shower.
I mainly massage the trapezius muscles and scalp.
I liked that I could get acupressure and massage on my face, scalp, and body.
It comes as a set that allows for various massages using heart shapes and multiple bumps, and even includes a case for storage when traveling.
It feels so refreshing to get a massage once in a while while watching TV.
