What it is and what it does
The Story
The perfect pairing of skin vitality with targeted environmental protection.
This potent serum fortifies skin against the appearance of oxidative stress while cultivating a healthy brilliance and even tone.
Skin appears more supple, firmer and uplifted.
The Promise
• Delivers sophisticated antioxidant protection
• Tone and texture are refined as natural radiance is reanimated
• Firmness and elasticity are enhanced as collagen is supported
• Supreme skin suppleness is realised
The Ritual
Smooth gently over face, neck, décolletage and backs of hands each morning.
Follow with your RATIONALE Essential Six formulations for day.
The Research
Human skin possesses a perfectly balanced network of antioxidant vitamins, minerals, enzymes and proteins that work in unison to prevent the formation of harmful, ageing free radicals and glycation products resulting from daily environmental exposure.
These same organic molecules are also the building blocks of healthy, glowing skin, boosting the synthesis of skin-firming collagen and elastin, while helping to control pigmentation and refine surface texture.
As we age, and as a result of sun and environmental damage, our natural levels of skin antioxidants are diminished, making topical supplementation essential.
