The materials we choose say a lot about a tool. At Rebel Skin, our tools are made from medical-grade stainless steel, chosen for function rather than fashion.
Why steel
- Rigidity and feedback: steel does not flex, so you can feel exactly how much pressure you are using and adjust it.
- Durability: it keeps its shape and finish, so your tool feels the same on day one as years later.
- Hygiene: the smooth, non-porous surface is easy to wash and dry.
- Temperature: steel feels cool to the touch and holds its temperature well.
A cooling touch
Chilled in the fridge for a few minutes, a steel gua sha or cryo stick gives a refreshing, soothing finish to a massage. Cool temperatures can make puffiness feel less noticeable for a while. It is a pleasant sensation, not a treatment, and research on lasting effects is limited.
Using it well
- Apply a facial oil or serum so the tool glides.
- Use light pressure and slow strokes, never scraping.
- Wash and dry the tool after each use.
Avoid broken skin, sunburn and active breakouts, and ask a doctor if you have a skin or circulation condition.
Choosing a tool you enjoy and can use consistently is the best way to build a ritual. Browse our gua sha tools or see how cold tools feel on the skin.
