Sebum
Definition
The natural oily substance produced by sebaceous glands in the skin. Sebum helps maintain skin moisture and creates a protective barrier against environmental damage. Lips do not have sebaceous glands, which is why they dry out faster than other skin areas and need external moisture. Jojoba oil's molecular structure closely mimics sebum, making it an ideal lip moisturizer.

Jojoba Oil
A liquid wax ester extracted from the seeds of the jojoba plant (Simmondsia chinensis). Its molecular structure closely resembles human sebum, allowing it to integrate with the skin's natural moisture system. Jojoba is rich in vitamins A, D, and E, and is non-comedogenic, making it ideal for sensitive skin. It provides sustained moisture by working in harmony with the body's own oils.
Emollient
A substance that softens and moisturizes the skin by filling gaps between skin cells with lipids (fats), creating a smooth, hydrated surface. Natural emollients like coconut oil and jojoba oil penetrate the skin to deliver moisture from within, unlike synthetic emollients that may only sit on the surface. Numbrrrz uses organic emollients that work with your skin's natural processes.
