A follicle is blocked and remains closed at the surface, trapping sebum beneath the skinExplanation: A closed comedone (whitehead) forms when a follicle is clogged with dead skin cells and sebum but remains closed at the surface — no oxidation occurs. An open comedone (blackhead) forms when the follicle is open, allowing oxidation of melanin in the sebum, turning it dark (the black color is not dirt). Inflamed comedones with bacteria become papules and pustules.

Humectant that draws moisture from the environment into the skinExplanation: Hyaluronic acid (HA) is a humectant — it attracts and binds water molecules, holding up to 1,000× its weight in moisture. HA draws moisture from the environment (and dermis) into the epidermis. It is found naturally in the skin and joints. In skincare, it improves hydration and plumps the appearance of fine lines. Emollients (lipids) and occlusives (petrolatum, beeswax) work differently.
