I bought this gua sha from HAUA after seeing so many celebrities carrying it in their bags on YouTube! After using it, I finally get why people are always recommending gua sha. I've been using it for about a year now, and my jawline has become so much more defined. I also massage my neck and shoulders, and the lines look much cleaner now. The oil coating makes it super smooth, so it glides over my skin without any tugging. Even the bumpy part on the ring is coated and really gentle, so it doesn't irritate my skin at all. You don't have to press hard to get a good massage, and I use it on my jaw, cheekbones, around my eyes (very gently!), between my brows, shoulders, and even my scalp—it's so cooling and refreshing everywhere! I loved it so much I ended up gifting a bunch of them to my friends. haha
