Are silk pillowcases good for your skin?
Silk pillowcases aren’t necessarily better than cotton or linen — those fabrics aren’t unkind to skin at all. However, silk is often considered a little gentler, particularly for people with sensitive or easily irritated skin.
There is currently no UK-backed scientific evidence proving that silk pillowcases improve skin health or treat skin conditions. That said, the natural properties of pure mulberry silk are why many people are switching to silk pillowcases and silk eye masks.
How pure mulberry silk feels against skin
Pure 6A grade mulberry silk is known for being exceptionally smooth, soft, and lightweight. Its naturally smooth surface creates less friction against the skin compared to coarser fabrics, like cotton or linen.
Because of this, silk may feel more comfortable for those who experience redness or sensitivity from fabric rubbing against their face overnight. Silk allows your face to glide more easily across the surface of the pillowcase.
Silk and moisture: What makes silk different?
Silk is naturally less absorbent than fabrics like cotton or linen. This is often considered beneficial because silk absorbs less of your skin’s natural moisture, oils, and any skincare products you apply before bed. As a result, you may feel more hydrated in the morning, but also there will be less build-up of oils and residue on the surface of your pillowcase, keeping it feeling cleaner and fresher between washes.
Satin vs silk: Why they’re not the same
Although satin may feel smooth like silk, most satin pillowcases and eye masks are made from polyester, a synthetic fabric.
Polyester is not naturally breathable and tends to trap heat and moisture. This can leave some people feeling hot or sweaty during sleep, particularly in warmer weather. For those with sensitive skin, trapped heat and moisture may contribute to discomfort or irritation.
Pure mulberry silk, by contrast, is a natural fibre that allows for better airflow and temperature regulation, which many people find more comfortable throughout the night.
