Gua Sha massage recommendations

I usually use high-frequency or ultrasonic devices, but this time I purchased an affordable Gua Sha massager to manage facial swelling and my jawline. While skin texture is definitely important, I've found that facial lines are very helpful in changing your overall impression. Since it is inexpensive and portable, carrying it around and using it whenever I have a spare moment seems very effective. The key is not to rub too hard, haha.
