Sebum and the Sebaceous Glands
the skin's oil-producing system, in which sebaceous glands attached to hair follicles secrete a waxy, lipid-rich substance called sebum. Sebum helps lubricate and waterproof the skin, contributes to the acid...

Desquamation
the natural, controlled shedding of dead cells from the outermost layer of the skin. This process is regulated by enzymes that break the bonds holding surface cells together, allowing them...

Cell Turnover
the process by which the skin produces new cells in its deeper layers and sheds mature cells from the surface. Efficient turnover supports smooth texture, an even tone, and a...

The Skin Renewal Cycle
the ongoing process by which skin generates new cells in its lower layers and sheds older cells from the surface. This continuous renewal keeps the barrier functional and typically takes...

Natural Moisturizing Factor (NMF)
a group of water-soluble compounds within the outer skin cells that attract and hold moisture, keeping the surface hydrated and supple. It includes amino acids, urea, lactic acid, and other...

Transepidermal Water Loss (TEWL)
the natural process by which water moves from the deeper layers of the skin to the surface and evaporates into the air. A certain amount is normal, but elevated levels...
