Follow with your recommended RATIONALE Cleanser and rinse clean, then apply your RATIONALE Essential Six formulations for night.

The Research
The skin’s outermost layer, the Stratum Corneum, is made up of an intricately balanced composition of lipids, including ceramides, cholesterol and triglycerides. This living barrier exists to protect skin from external hazards, keeping it hydrated and supple while helping to shield against sunlight and other environmental aggressors.

A thorough nightly cleansing regimen can assist in the replenishment of vital Stratum Corneum lipids and proteins, which are otherwise diminished a result of ageing and environmental damage.

Skin lipid esters assist in breaking down surface debris, including sunscreen actives and makeup which are removed with the addition of water, while simultaneously boosting concentrations of native surface lipids to fortify barrier function.

The Promise

• Skin appears more hydrated.
  

• Skin feels softer and more supple.

• Gently cleanses to optimally prepare skin for night-time actives.

The Ritual

Follow with your RATIONALE Essential Six formulations for night. 

The Research

The skin’s outermost layer, the Stratum Corneum, exists to perform its vital barrier function.

An exquisitely balanced composition of lipids, comprised of ceramides, cholesterol and triglycerides comprise a living barrier that keeps skin moist and supple, helping to prevent infection by providing a shield against sunlight and other environmental aggressors. 

These ‘living lipids’ are also crucial to cell-to-cell communication and biochemical signalling, forming a dynamic, interactive interface between the skin and the outside world.

Stratum Corneum lipids and proteins are synthesised in the skin’s upper layers, but the efficiency of this process diminishes with age and environmental damage, leading to skin dryness and sensitivity. Topical lipid supplementation through the processes of cleansing and moisturising can replenish and stabilise this biological defensive function.

Foaming cleansers tend to dry and strip the skin of precious nutrients and lipids, increasing dehydration and reactivity. The correctly balanced combination of intercellular lipids, vitamins and botanicals can gently remove daily debris, including sunscreens and pollution, while augmenting and reinforcing Stratum Corneum barrier structures.

Complexion health, vitality and beauty are highly dependent upon the acidic pH of the Stratum Corneum, the skin’s outermost layer.

Skin protects itself from the breakdown of its connective tissues) by upregulating enzymes that assist in collagen and elastin connective tissue synthesis. These enzymes require acidic surface conditions to function optimally.

Breakouts, premature ageing, pigmentation and other signs of environmental damage can occur when the skin is too alkaline (the opposite of acidic).

A nightly cleanse with a complex of hydroxy acids, phospholipids and amino acids can assist in gently recalibrating skin pH back to a healthy, acidic state, helping to restore clarity and firmness.
