The gua sha + roller
The gua sha + roller set are a game changer for me, I absolutely love how they are both "naturally" cooling so I don't need to stick them in a fridge. In the morning I can easily refresh and wake up my skin with the roller. Thick Skin works as a great slip agent with my gua sha and I don't feel nervous about tugging on my skin too hard. Because it's not porous, I'm also rest assured that neither of these tools will get a buildup of bacteria as much as jade or rose quartz tools. The only complaint I had is the packaging for Thick Skin (especially the dropper), but it seems like they updated it with the new design/name (Slick Skin), so I'm excited to try that someday.
