The Story

Profound clarity and radiance.

A gently nourishing milk concentrate that resets skin’s pH to a healthy balance while promoting skin calmness. This formulation promotes skin refinement to fortify barrier function, amplifying moisture levels and enhancing skin resilience to radiant effect.

The Promise

Calms, clarifies and rejuvenates skin.

Gently recalibrates skin pH to enhance ongoing clarity.

Supports skin resilience.

Skin feels hydrated, softer and more supple.

A more radiant tone and texture is revealed.

The Research

A vibrant, radiant complexion is intimately connected to the pH of the skin’s outermost layer, the Stratum Corneum.

Sensitivity, barrier breakdown, Pigmentation and premature Ageing are all consequences of environmental damage. These occur as a result of excessive solar exposure, causing the skin’s pH to shift from a healthy acidic state to alkaline, triggering the upregulation of enzymes that break down connective tissue and erode protective barrier structures.

Signalling peptides in human skin direct all metabolic processes, including desquamation (cell turnover), cellular differentiation (cellular function), and hydration. Short-chain protein sequences and ceramides are critical in these intercellular communication processes.

Directions of Use:
