During the night, the body naturally releases sweat, even if you don’t realize it. On average, one person loses between 500 and 700 ml of sweating per night. This moisture is impregnated in the tissues and leaves yellow marks over time.

• Body oils

The skin continuously produces natural oils which are deposited on the bedding. Unlike sweating, these oils are more greasy and more difficult to remove. Over time, they enter the pillow and contribute to its yellowing.

• Saliva

If you tend to drool while sleeping, it may also speed up the discoloration of your pillow. Saliva contains enzymes that, by accumulating, change the colour of the tissue.

• Care products and make-up

Moisturizing creams, serums and other care products applied before bedtime may also stain your pillow. Even after washing the face, residues may remain on the skin and transfer onto the tissue at night.
