Your skin barrier — also known as the stratum corneum — acts as your body’s frontline defense. Think of it as a brick and mortar wall, where corneocytes (skin cells) are the bricks and lipids (ceramides, cholesterol, and fatty acids) form the mortar that seals everything together.
When intact, this barrier keeps moisture in and irritants out.
When damaged, microscopic gaps form — allowing water to escape and irritants to enter.
That’s why your skin feels tight after cleansing — it’s literally dehydrating itself through a process called Trans-Epidermal Water Loss (TEWL).
When your skin feels tight, it’s not clean — it’s stressed.
Most often, this happens because your lipid balance is disrupted.
Common causes include:
Over-cleansing or using foaming, high-pH cleansers
Overuse of exfoliating acids or retinoids
Harsh weather or indoor heating
UV exposure and pollution
Once the barrier weakens, the skin can’t hold water efficiently. That taut, dry feeling is your skin signaling water loss and reduced elasticity.
