The Story

This rejuvenating overnight formulation gently supports skin renewal for a visibly reanimated appearance by morning.

Skin plumpness and firmness are enhanced as collagen production is nurtured, while repair processes are supported with this targeted and nourishing GelCrème formula.

The Research

The signs of environmental damage include wrinkles, sagging and pigmentation, and are related to sun exposure and pollution combined with natural ageing.

To a certain extent, human skin has the capacity to self-repair. However, as we age, and as a consequence of environmental damage, these natural restorative processes are diminished.

Topical treatment can assist in restoring and rejuvenating skin, helping to reverse signs of environmental damage to illuminate and refine skin luminosity.

For skin that does not easily tolerate topical Retinoids (Vitamin A), a gentle botanical alternative known as Bakuchiol, when combined with DNA Repair Enzymes, can assist in restoring repair processes, helping to reverse signs of environmental damage, restoring skin firmness and luminosity.

The Ritual

The Research

Acidic skin pH plays a critical role in optimising cellular differentiation (cellular function), desquamation (cell turnover) and the synthesis of vital skin lipids.

Environmental skin damage caused by the sun, pollution and temperature extremes results in skin pH shifting from acidic to alkaline. This can cause the downregulation of enzymes vital to barrier lipid synthesis and connective tissue regeneration (collagen and elastin).

The outcome of this is the typical pathology of premature ageing, including dryness, sensitivity, pigmentation and skin laxness.

Topical application of hydroxy acids can recalibrate skin pH back to a desirable acidic levels, refining texture, smoothness, hydration, tone and clarity.

RATIONALE #4 The Crème

admin_m — Mon, 18 Oct 2021 08:54:37 +0000

The Story

Complexion calmness, suppleness and strength.

#4 The Crème masterfully re-establishes skin’s barrier integrity while inviting a feeling of unparalleled comfort. As moisture levels are replenished, barrier function is fortified and skin luminosity is amplified.

The Promise

Natural barrier integrity is strengthened
Skin’s outermost layer is fortified, helping to main and augment moisture levels
Firmness is enhanced as hydration levels are intensified
Soothes and calms skin to reduce skin sensitivity
Skin appears naturally dewy and radiant

The Ritual

Smooth gently over face, neck, décolletage and backs of hands.

The Research

A perfectly balanced array of specialised bioactive lipids, including ceramides, cholesterol and triglycerides, form a vital component of the skin’s barrier function as part of the Stratum Corneum, the skin’s outermost layer.

As a dynamic, interactive interface between the skin and the outside world, these ‘living lipids’ are also crucial in modulating immune responses and empowering cell-to-cell communication.

Topical treatment with a precise combination and ratio of lipids, vitamins and proteins can alleviate skin sensitivity and dryness by replenishing and stabilising the barrier function of the Stratum Corneum, which diminishes throughout life due to natural ageing and environmental damage.

RATIONALE #4 The PreCleanse Balm

admin_m — Mon, 18 Oct 2021 08:52:00 +0000

The Story

#4 The PreCleanse Balm is a restorative prelude to your evening cleansing ritual, nourishing as it elevates moisture levels and gently removes all traces of makeup, sunscreen and impurities. Skin feels refined and hydrated as it is perfectly prepared for your second cleanse.

The Promise

Replenishes intercellular lipids to restore skin integrity.
Helps to balance, nurture and rehydrate skin.
Balm-to-oil emulsion removes all sunscreen, makeup and impurities.
Skin feels comforted, softer and more supple.

The Ritual

Massage gently over dry skin.

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 Research

Targeted cells and tissues form the skin’s own specialised immune system, playing a vital daily role in the prevention of environmental damage, allergy and disease.

Skin immunity, clarity and firmness are directed by a delicately balanced interfusion of biologically active barrier lipids including ceramides, triglycerides and cholesterol. This protective function is fortified by the flexible yet stalwart proteins of the Stratum Corneum’s outermost cells, the corneocytes.

Synthesis and maintenance of these vital barrier constituents is highly dependent on Stratum Corneum moisture levels, supported by B-group vitamins, signalling peptides and Essential Fatty Acids.

The Ritual

Warm the crème between your fingertips and smooth gently over face, neck, décolletage and backs of hands.

Use in synergy with your RATIONALE Essential Six formulations for remarkable skin luminosity.

The Research

Long have we studied the profound interaction between human skin and sunlight, and the extent to which our skin can protect itself from solar and environmental stressors.

Epigenetic influences, including sun exposure and pollution, diminish the skin’s native protective reserves of Melanin, Vitamin D and Heat Shock Proteins, which form a first-line defence against UV, Visible Light and Infrared Radiation. The result is dull, dehydrated skin prone to inflammation and premature ageing.

For more than 30 years, RATIONALE Research has focused on identifying, optimising and deploying these Skin Identical vitamins, minerals, antioxidants and proteins in our Environmental Protection Formulations.

Melanin, a Skin Identical antioxidant, naturally protects epidermal keratinocytes by forming a protective cap over DNA that defends against UV light. When applied topically, Melanin acts as a natural sunscreen booster that enhances protection against the entire Solar Constant. In addition, Vitamin D precursors––which are found in the plasma membranes of skin cells—are stimulated with exposure to sunlight and synthesise active Vitamin D, which has photo-protective effects, decreasing DNA damage and oxidative stress while reducing inflammation. Similarly, Heat Shock Proteins are able to shield skin cells from thermal damage by expanding and unfolding in the presence of heat to protect cells from becoming dry and dehydrated.
