/SEE-bum/
Definition
The natural oil produced by sebaceous glands in the skin that keeps it moisturized. Overproduction clogs pores and contributes to acne and shine.
Sebum is the skin's built-in moisturizer — a waxy, oily substance produced by sebaceous glands attached to every hair follicle. In the right amount, it keeps the skin's barrier flexible and water-resistant. In excess, it mixes with dead skin cells inside pores to create the perfect environment for blackheads, whiteheads, and acne.
Exfoliation
The process of removing dead skin cells from the skin's surface, either physically (scrubs, devices) or chemically (acids, enzymes) to reveal fresher skin.
Salicylic Acid
A beta-hydroxy acid (BHA) that penetrates into pores to dissolve oil and dead skin buildup — especially effective for acne, blackheads, and congested skin.
BHA (Beta-Hydroxy Acid)
A family of oil-soluble acids — most notably salicylic acid — that penetrate into pores to break down excess sebum and dead skin. Ideal for oily, acne-prone skin.
