Silk is a delicate fabric and the more you look after it, the more it will look after you(your skin and hair too).

o maximize quality and durability of your mask, we recommend:

• pH neutral liquid detergent 
• machine wash delicate below 30°C (86°F) (delicates wash bag), or cold.
• hand wash below 30°C (86°F), or cold.
• dry clean
• no trichloroethylene
• iron low heat
• steam or dry
• do not bleach
• do not tumble dry

Most people recommend or every few days—whatever works best for your skin's needs. Most of the time, that either means hand-washing it with a skin-friendly, hypoallergenic detergent that's free of any fragrance or washing it in the washing machine in a mesh wash bag, just like you'd wash other delicate items . To save you time (and water!), that might mean buying a few different silk eye masks and washing them at the end of the week.
