Ingredient Breakdown

Aqua (Water)

Category: Solvent

Function in Formula: Primary medium for ingredient dispersion.

Purpose in This Cleanser:
Water forms the base of the formulation, allowing surfactants, emollients, humectants, and barrier-support lipids to distribute evenly across the skin during cleansing.

Glycerin

Category: Humectant

Function in Formula: Moisture-retention agent.

Purpose in This Cleanser:
Glycerin attracts and retains water in the stratum corneum, helping maintain hydration during cleansing and minimizing post-wash tightness, particularly for dry or sensitive skin types.

Sodium Cocoyl Isethionate

Category: Mild Anionic Surfactant

Function in Formula: Primary cleansing agent.

Purpose in This Cleanser:
Effectively removes dirt, excess oil, and sunscreen while maintaining improved skin barrier compatibility compared with traditional sulfate-based surfactants.
