Can a cotton pillowcase make pregnancy melasma worse?

Yes, indirectly. Melasma is worsened by heat and friction, and cotton traps warmth against the skin while its rough texture rubs the already reactive pigmented zones all night. A perfectly smooth 100% mulberry silk pillowcase (no embroidery), like Silkhouse's, has natural thermoregulating properties and doesn't drag on sensitive skin, helping keep hormonal pigmentation calmer.

Pregnancy Mask: Why Cotton Worsens Melasma

The Cotton Trap and Hormonal Pigmentation

Melasma, often called the "pregnancy mask," is triggered by hormonal shifts that make pigment-producing cells hyperactive, especially on the forehead, cheeks, and upper lip. Heat and friction both aggravate this hyperpigmentation. Cotton, a fiber that traps heat and rubs against the skin all night, keeps these already reactive zones warm and irritated for eight hours straight.

The Cooling Solution: 22 Momme Silk

Mulberry silk has natural thermoregulating properties and an exceptionally smooth surface that doesn't trap heat against the skin. It glides instead of dragging across already fragile, hyperpigmented zones. The result: less nightly aggravation of your melasma, and skin that feels calmer by morning.

        "Beware of false good ideas: a pillowcase for pregnancy-sensitized skin must be perfectly smooth. Avoid embroidery and sewn-on logos — those synthetic threads create friction exactly on the pigmented zones. The minimalist design of Silkhouse silk isn't an aesthetic choice, it's a skin-calming requirement."
