Frequently asked questions

• Why is mulberry silk better than satin for a sleep mask?

  Mulberry silk is a natural protein fiber harvested from silkworm cocoons, fundamentally different from synthetic satin which is simply a weave pattern applied to polyester or nylon. The protein structure of mulberry silk is naturally smooth at a microscopic level, producing significantly less friction against delicate facial skin than any synthetic alternative. This matters specifically for sleep masks because reduced friction means fewer sleep creases forming around your eyes overnight, less mechanical stress on delicate under-eye skin over time, and no moisture absorption stripping your skin dry while you sleep. Satin looks similar but is a petroleum-based synthetic that traps heat, pulls moisture from your skin, and degrades faster with repeated washing. The Lumana Pure Mulberry Silk Sleep Mask uses 100% pure mulberry silk, not a blended or coated fabric, so you get the full skin and sleep benefits that cheaper satin alternatives simply cannot deliver.

• Is a silk sleep mask good for sensitive skin?

  Yes. Mulberry silk is naturally hypoallergenic and free from the synthetic chemicals, dyes, and finishing agents found in polyester and satin alternatives. The ultra-smooth fiber surface produces minimal friction against sensitive skin, making it one of the safest materials for nightly contact with the delicate eye area. The Lumana Pure Mulberry Silk Sleep Mask is particularly suitable for people with eczema-prone skin, rosacea, contact dermatitis, or general skin sensitivity who have experienced irritation, redness, or breakouts from foam or synthetic fabric masks. The natural breathability of silk also prevents the moisture buildup inside the mask that can trigger congestion or irritation around the eye contour area during prolonged wear. If you have reactive skin and have avoided sleep masks because of irritation, pure mulberry silk is the material to try first.

• Does a silk sleep mask help prevent wrinkles and puffiness?

  Yes, through two specific mechanisms. First, the ultra-smooth mulberry silk surface dramatically reduces the friction that causes sleep creases, the temporary compression lines that form when fabric drags against your skin during the night. Over years of nightly repetition, sleep creases contribute to permanent fine line formation around the eyes where skin is thinnest. Silk eliminates the friction that causes this. Second, unlike cotton or synthetic fabrics that actively absorb moisture from your skin surface, mulberry silk does not pull hydration away from the delicate under-eye area while you sleep. This helps maintain skin moisture levels overnight, which reduces the morning puffiness and tightness caused by dehydration and fabric compression. The Lumana Pure Mulberry Silk Sleep Mask delivers both benefits simultaneously through the natural properties of the fiber itself, with no added treatments or coatings required.

• Is a mulberry silk sleep mask breathable for all night wear?

  Yes. Mulberry silk is a naturally temperature-regulating fiber that adapts to your body heat rather than trapping it. Unlike memory foam or synthetic fabric masks that feel warm and stuffy after a few hours of wear, a silk mask maintains a consistently cool, lightweight sensation throughout the night. This makes the Lumana Pure Mulberry Silk Sleep Mask particularly well suited for warm sleepers, people in warmer climates, and anyone who has abandoned other sleep masks due to overheating or discomfort during extended wear. The natural breathability also prevents the condensation and humidity buildup inside the mask that causes skin congestion with non-breathable synthetic materials during 7 to 9 hour sleep periods. For year-round use across Canadian climate extremes, silk performs consistently in both warm summer nights and dry winter indoor heating environments.

• How do you wash and care for a silk sleep mask?

  Hand wash your Lumana silk sleep mask in cool water using a dedicated silk-safe detergent or gentle baby shampoo for best results. If hand washing is not practical, machine wash on the delicate cycle inside a mesh laundry bag using cool water only. Never use regular laundry detergent as it strips the natural sericin protein coating that gives mulberry silk its smooth, skin-beneficial properties. Gently squeeze water through the fabric without wringing or twisting. Rinse thoroughly and lay flat on a clean dry towel to air dry away from direct sunlight and heat sources. UV exposure and heat degrade silk fiber and cause color fading over time. Never tumble dry or iron directly on the silk surface. With proper care, wash every 7 to 10 days during nightly use to maintain hygiene and preserve the silk fiber quality and softness long term.

• How is the Lumana silk sleep mask different from cheaper silk masks?

  The key difference is material grade. Many sleep masks marketed as silk use blended fabrics, silk-feel polyester, or low momme weight silk that looks similar but lacks the durability and skin benefits of pure mulberry silk. The Lumana Pure Mulberry Silk Sleep Mask uses 100% pure mulberry silk with no synthetic blending, delivering the full hypoallergenic, friction-reducing, and moisture-retaining properties that make mulberry silk genuinely beneficial for skin and sleep. The mask is available in six colors including black, champagne, dark blue, light pink, grey, and purple, with an adjustable elastic strap that fits most adult head sizes without slipping or tightening during the night.

• Is the silk sleep mask suitable for side sleepers?

  The Lumana Pure Mulberry Silk Sleep Mask is comfortable for side sleepers who prioritize fabric feel and skin benefits over structural eye pressure protection. The flat silk design is lightweight and soft against pillow contact. However, if you are a side sleeper who requires total blackout performance and zero eye pressure under pillow compression, the Lumana 3D Contoured Sleep Eye Mask is the better choice as the raised eye cup structure maintains its shape and blackout seal under lateral pressure. For back sleepers and combination sleepers who move less during the night, the silk mask delivers exceptional comfort and beauty benefits.

• Does the silk sleep mask come with anything included in the packaging?

  Yes. The Lumana Pure Mulberry Silk Sleep Mask is individually packaged for hygiene and arrives ready for gifting or personal use. The adjustable elastic strap is pre-fitted and ready to wear from the moment you open the box. The six available colors make it a popular gift choice for wellness-focused occasions. Every order ships with free tracked delivery across Canada and the USA with duties and taxes prepaid, and is covered by Lumana's 30-day return policy.
