^Mixed Color Bundle of 2 Face Masks in CUIONS Gold & ZINCOOL White.


[Sweat/Water/Splash Resistant] Suitable for Pre/Post Sports
[Anti-Ageing] Copper ions stimulate collagen production/reduce wrinkles
[Bactericidal] [Self-Cleaning]⁵ Prevents mask acne/Anti-odour
[UV-Protective] Certified UPF 50+ with UV-Protection for Melasma, Pigmentation

*UPF 50+ qualifies for excellent protection according to the Skin Cancer Foundation Seal of Recommendation guidelines. A UPF 50 fabric blocks 98 percent of the sun’s rays and allows two percent (1/50th) to penetrate, thus reducing your exposure risk to UVA and UVB radiation, which cause photoaging, pigmentation and skin cancers.

**Laboratory studies show 99.9 percent reduction in Staphylocuccus Aureus upon contact with CUIONS™ copper fibre.


Droplet Filtration: Equivalent droplet filtration to surgical mask

For Acne Prone Skin – Dermatologist Recommends:
Maskne treatment with Blemish Spot Cream and Anti-Acne Zinc Oxide Loose Powder. These are non-irritating (inert formulations) that will not increase skin irritation when worn and is suitable to be worn under a face mask. Usage of retinoids/benzoyl peroxide/salicylic acid formulations will have increased risk of irritant contact dermatitis when worn under a face mask.

Fight Maskne with our anti-acne bundle here. Treat your mask acne here using the SilkPeel Home Medi-Facial Kit.

Skincare makeup is recommended for use under our CUIONS™ Copper Mask
CellTalk Cosmeceutical CC cream
Feel Good Cosmeceutical Blush Cream to Powder/Lip-Cheek Stain
The LipSerum Stick

Recommended pimple cream for use under a fabric mask. Pimple creams which contain benzoyl peroxide/sulfur will bleach/stain the fabric. Use of retinol/retinoids/salicylic acid/AHA skincare ingredients while wearing a face mask will cause skin irritation¹.

CARE: Machine washable with regular detergent. Use delicates cycle with laundry bag to minimise wear and tear. Do not tumble dry. Do not use any fabric softeners when washing or drying. Do not use chlorine bleach as it may degrade the ear elastics over time. Wash prior to first use and daily thereafter, or between users, whichever comes first. After laundering and prior to use, inspect face mask for fabric integrity, do not use if there are rips or tears.

Precautions: Not for use in individuals with allergy to copper. ZINCOOL Anti-Maskne Oil Control Mask containing zinc nanoparticles is available for individuals allergic to copper*. Individuals should not use any form of facial masks when exercising, as this impairs the ability to breathe comfortably and could also result in lowered oxygenation levels10. Not for use in the presence of a high intensity heat source or flammable gas, or in high risk aerosol generating procedures. Do not use if damaged or if you have sensitivity to copper or polyester.

Disclaimer: While copper impregnated textiles have been shown to be effective in limited studies as antiviral agents effective against coronaviruses and respiratory viruses, Dr.TWL Biomaterials does not currently recommend the fabric mask for medical staff usage in high risk healthcare settings. The standard remains the surgical mask (suited for use with our LyoSilk Mask Slip) for droplet precautions and the N95 mask for airborne precautions. The CUIONS Copper Face Mask is intended for use by the general public to cover their noses and mouths, in accordance with CDC recommendations, to help prevent the spread of SARS-CoV-2, during the COVID-19 pandemic.

As the Copper Silk Face Masks are hand cut and sewn, please note that there may be slight differences between each piece, whilst maintaining the overall shape, fit and size.

*If you have a history of developing rashes to copper metals, the zinc nanoparticle fabric face mask is recommended. Allergy to copper is not common. If you develop rashes whilst wearing the mask, please discontinue use and consult an accredited dermatologist.
