A healthy lipid barrier is crucial for a healthy stratum corneum and the entire epidermis. When the barrier is severely damaged, the skin's natural biological processes are activated as a result.Continuous damage to the stratum corneum, caused by a surfactant with excessive fatty acid extraction might eventually lead to barrier damage, dryness and irritation.

Continuous damage to the stratum corneum, caused by a surfactant with excessive fatty acid extraction might eventually lead to barrier damage, dryness and irritation.

The structural integrity of the stratum corneum is provided by the corneocyte bricks, while other features such as water transport, barrier properties, and the ability to absorb and relieve stress are regulated by intercellular lipids.
