Dermatologists in Australia and globally have recommended silk for patients with eczema, atopic dermatitis and sensitive skin conditions for decades. The recommendation is not aesthetic — it is clinical. Mulberry silk has specific physical and biochemical properties that make it measurably better for compromised skin than any alternative fabric, including cotton, bamboo and synthetic fibres.
Here is what the clinical evidence actually shows, and what it means for the fabric you choose to sleep in.
A 2017 pilot study published in dermatology literature on DermaSilk — a clinical-grade silk textile used in therapeutic settings — found significant improvement in acne vulgaris on the back and trunk after consistent skin contact with silk over six weeks. A dedicated clinical trial (NCT00767104) found measurable reductions in acne lesions attributed to lower bacterial transfer when patients slept on silk-like surfaces.
The Journal of the European Academy of Dermatology published research finding that cotton bedding and clothing was associated with increased transepidermal water loss (TEWL) in patients with atopic dermatitis compared to silk. TEWL — the rate at which moisture evaporates through the skin barrier — is the primary measure of skin barrier function. Higher TEWL means a more compromised barrier. Silk reduced TEWL. Cotton increased it.
Dermatologists note that silk causes considerably less friction than cotton and absorbs far less moisture and skin oils — keeping overnight skincare exactly where it was applied rather than wicking it into the fabric.
Mulberry silk is a protein fibre. Its molecular structure — composed primarily of fibroin with a coating of sericin — is closer to the protein structure of human skin than any other textile. This is why it is described as biocompatible: the skin's immune system does not recognise it as an irritant the way it may recognise synthetic fibres or the chemical finishes applied to cotton.
Sericin, the natural gum protein that coats silk fibres, has demonstrated antimicrobial properties in laboratory conditions. It resists the growth of dust mites, mould and common skin bacteria. This is why silk is described as naturally hypoallergenic — not because it has been treated to be, but because of its inherent protein chemistry.
The triangular cross-section of silk fibres also matters. Unlike the round cross-section of cotton fibres, silk's triangular shape means the surface that contacts skin is extremely smooth, creating minimal friction. In practical terms: where cotton creates microscopic abrasion against the skin surface with every movement during sleep, silk glides. For skin that is already inflamed, reactive or compromised, this reduction in mechanical friction makes a significant difference to overnight comfort and healing.
The clinical recommendations for silk sleepwear are strongest for the following skin conditions, all of which are common among Australian women in the 35–60 age group:
Eczema and atopic dermatitis — silk reduces the friction and bacterial exposure that trigger flare-ups overnight, and does not absorb the emollients and barrier creams applied before bed. Dermatitis clinics in Australia and the UK use DermaSilk garments as part of therapeutic protocols for severe atopic dermatitis.
Sensitive and reactive skin — silk's hypoallergenic properties and absence of chemical finishes make it the lowest-irritation fabric available for skin that reacts to standard textiles or laundry products.
Acne-prone skin — silk reduces the bacterial transfer and mechanical irritation that aggravate existing blemishes overnight, and allows acne treatments applied before bed to remain on the skin rather than being absorbed into the fabric.
Perimenopause skin — hormonal changes during perimenopause often cause skin to become more reactive, thinner and more prone to moisture loss. Silk's thermoregulatory properties and low moisture absorption make it particularly appropriate for this skin state.
The clinical evidence supports one practical recommendation: if you have any of the skin conditions above, or if your skin is simply drier, more reactive or more sensitive than you would like, the fabric you sleep in should be mulberry silk, not cotton.
A full night of skin contact with cotton — eight hours of friction, moisture absorption and bacterial exposure — actively works against the skin barrier. A full night in mulberry silk provides the opposite: minimal friction, moisture retention and a hypoallergenic surface that allows the skin to repair itself without mechanical interference.
