The CUIONS™ copper silk face mask contains copper nanoparticle impregnated fabric. It is rigorously lab tested for the active release of copper ions that are clinically effective for anti-ageing by promoting collagen production and reducing pigmentation. It is also certified for anti-microbial functions to actively prevent and treat mask acne. The CUIONS™ silk face mask has been specifically engineered to attain UPF50 certification*, the gold standard in UV-protective fabrics.

Our CUIONS™ Anti-Ageing + Anti-Acne Copper Silk Face Mask has been laboratory tested to kill Staphylococcus Aureus**, a common bacteria that can cause secondary skin infections in acne¹ and worsening of facial eczema². Bacterial/Fungal infections can cause mask acne, also known as occlusion acne. The surface is also water/splash resistant with adjustable ear loops.

This copper nanoparticle mask is clinically proven to be more hygienic than the standard fabric mask. It has anti-odor properties by killing bacteria/fungi/microbes that come into contact with the mask3. It is particularly suited for comfortable wear against your skin over prolonged periods. Copper nanoparticle impregnation is also backed by clinical studies4,5,6,7 to have active skincare properties (anti-wrinkle, anti-ageing) due to stimulation of collagen growth through contact with copper ions actively released on contact with skin. Data from two randomised controlled trials demonstrate statistically significant reduction in facial wrinkles after 2 weeks of exposure to copper oxide infused textile5,6.

*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.

Dermatologist Recommends:
For acne prone skin:
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

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.

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.

Precautions: Not for use in individuals with allergy 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 levels8. 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.

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.
