A dry skin type does not produce enough of which substance?

Explanation:
Sebum keeps the skin moisturized and forms a protective barrier. In a dry skin type, there isn’t enough sebum being produced by the sebaceous glands, so the skin lacks natural lubrication and becomes rough, flaky, and easily irritated. Sweat is produced by sweat glands for cooling, not for long‑term moisture; keratin is a structural protein that gives skin strength, and pigment (melanin) determines color. Neither keratin nor pigment nor sweat level explains dry skin, making sebum the key factor here.
