When it comes to cryrotherapy tools, there are many different types to choose from—not to mention many different materials. Stainless steel ice rollers, jade facial rollers, glass cryo globes…some cryo tools are even made from plastic or aluminum. But of all these materials, only one stands out due to its ability to retain coolness and its potential to reduce the skin damaging effects of everyday inflammation. What is it? Copper. Let’s take a deeper dive and learn more about why copper is the best choice for your skin’s health—and why we used it for our new COOL Sonic Depuffing device.
Why is copper ideal for cooling face rollers?
Superior ability to retain cold
Experts say copper is the best material for transferring and retaining coolness because of its exceptionally high “thermal conductivity.” Copper rapidly absorbs and dissipates thermal energy, allowing it to quickly reach and maintain a cold temperature. Fun fact: Copper is nearly 400 times more thermally conductive than glass. So, if you’ve ever wondered why icy cold cocktails like Moscow mules are served in copper mugs, now you know!
When it comes to your skin, copper absorbs and dissipates thermal energy in the same way. Copper not only rapidly reaches an optimal cool skin-cooling temperature but also helps absorb or “pull” heat from your skin’s surface. Compared to stainless steel, jade, glass and plastic, copper delivers faster, more effective and longer-lasting coolness. Our proprietary SonicCool™ cools down in seconds and (unlike other materials) doesn’t lose its cool.
Powerful “inflammaging” benefits
Copper is an essential trace mineral, which your body uses to activate enzymes involved in collagen formation, elastin structure, and skin firmness. Copper also plays an important role in tissue repair and regeneration. Studies show it can promote faster wound healing, support the formation of new blood vessels, and help repair a damaged skin barrier.
As a skincare ingredient, copper also has demonstrated anti-inflammatory activity and may help reduce redness or irritation, in addition to promoting healing after dermatological procedures. When used in facial cooling, copper’s ability to retain coolness gives superior skin-soothing and visible inflammation-reducing benefits. Why is this important? Minimizing daily inflammation supports skin longevity and helps your skin stay stronger and healthier.
Naturally antimicrobial
Copper surfaces are strongly antimicrobial. Copper can kill or inhibit bacteria, fungi and some viruses. For this reason, copper-infused fabrics and medical materials are sometimes used for infection control. When it comes to your skin, copper can help reduce bacterial load — something that’s especially beneficial if you struggle with acne.
How does copper compare to jade or stainless steel?
Compared to face rollers made from stainless steel, jade, glass or plastic, copper reaches a cold temperature more quickly and maintains that temperature much more effectively. Copper is also naturally antimicrobial and helps inhibit the spread of acne-causing bacteria. Overall, copper is the best choice to help quickly reduce the look of redness and daily inflammation and support a strong skin barrier.
Will copper turn my skin green?
No, a copper face roller will not turn your skin green. Green discoloration happens when copper reacts with sweat. It’s most commonly seen when cheap copper jewelry is worn for long periods of time and sweat becomes trapped under rings or bracelets. With a copper face roller, you’re using it for short periods of time and there’s no buildup of sweat to cause a reaction. In addition, COOL uses premium-quality copper that inhibits oxidation (unlike cheap copper).
There you have it...why copper is the coolest (and most beneficial) material around when it comes to face rollers. We’re excited for you to try new COOL and discover the benefits for yourself.
