We've seen millions of Instagram trends come and go, from glitter roots to cold brew hair. While most of them have been pretty modern creations that have taken off, the latest uber-popular beauty hack dates all the way back to ancient China. Gua Sha stones are the newest must-have in your beauty arsenal, but the oddly-shaped pieces of rose quartz and jade can look a little intimidating. Traditionally, the stones are used as part of a Chinese massage technique called scraping, but this new take on the art uses a much gentler version for the face. So, what does it do - and more importantly, do we need it in our lives?

The answer is yes. Gua Sha has been used for hundreds of years to improve the circulation throughout your body. When the stones are applied to the face with medium to heavy force, it can help drain the lymphatic system and toxins, leaving the skin smooth and much less inflamed. It might look a little complicated to the untrained eye, but using these delicate tools couldn't be easier. Simply apply your favorite face oil (we love Burt's Bees Facial Cleansing Oil as it's 100% natural and won't break the bank) and drag the tool in outward motions using the flat end. You can thank us later.

There's a lot to be said for opting to go for a Gua Sha back massage too, but this should only be done by a trained practitioner. Many praise the treatment for helping relieve them of longstanding symptoms such as poor circulation and back pain. According to Cosmopolitan, oil-lubricated skin is scraped to loosen muscles in tense areas, including the neck and shoulders. It's not for the faint-hearted though, as you're usually left with red marks as a result of the treatment that can last up to a week.

If you're thinking about trying Gua Sha for your face though, don't panic - the only thing red will be the faces of your friends when they realize they haven't tried it yet. Check out the above video from Allure Korea to see how it works. Are you a Gua Sha veteran? Let us know in the comments!
