Quality & Certification

At SOIELA, every item is designed to accompany daily self-care rituals: sleep, hair, and skin. We select long-fiber mulberry silk, grade 6A, known for its softness, fineness, and naturally luminous touch.

Our products are designed for direct contact with the skin, face, and hair. This is why we pay particular attention to textile quality, silk density, and the certification of finished products.

Long-fiber mulberry silk, grade 6A

Mulberry silk is one of the most prized silks for sleep and self-care accessories. At SOIELA, we favor long-fiber silk of grade 6A, selected for its regularity, softness, and naturally smooth appearance.

Thanks to its delicate surface, mulberry silk helps limit friction during the night. It is particularly suitable for hair and skin care routines, especially for dry, curly, textured, colored, or fragile hair.

22 momme and 19 momme: two densities adapted for every use

Momme is a unit used to measure silk density. The higher the momme count, the denser, more enveloping, and more durable the material is over time.

At SOIELA, our silk pillowcases and sleep caps are made from 22 momme silk. This density offers a thicker and more durable material, ideal for regular nightly use in contact with skin and hair.

Our lighter accessories, such as sleep masks and silk scrunchies, are crafted from 19 momme silk. This density results in a soft, flexible, and comfortable material for everyday wear.

Why choose SOIELA silk?


SOIELA prioritizes long-fiber mulberry silk, grade 6A, to offer accessories that are both soft, elegant, and suitable for daily use. Unlike synthetic satin, which refers to a type of weave often made from polyester, silk is a natural fiber.

Compared to cotton, silk offers a smoother surface, which further limits friction on hair and skin during sleep. It is particularly appreciated in nighttime beauty routines because it accompanies the natural movement of the face and hair without a rough sensation.

We also choose different densities depending on the use: 22 momme for the most frequently used night products, such as pillowcases and bonnets, and 19 momme for delicate accessories, such as sleep masks and scrunchies.

Designed for skin, hair, and sleep

Because our products are in direct contact with the face, skin, and hair, we pay particular attention to touch, safety of use, and daily comfort.

A silk pillowcase, a sleep cap, a sleep mask, or a scrunchie are not just accessories. At SOIELA, they are designed as gentle gestures integrated into a care routine: protecting hair, limiting friction, supporting rest, and providing a feeling of comfort night after night.
