Antioxidants and Vitamin C have powerful brightening and firming properties, which work to even skin tone and protect the skin from the downstream effects of solar damage and pollution.

Following sun exposure, it’s essential to fortify the skin’s barrier and nourish the complexion. Skin Identical Ceramides strengthen barrier function, while soothing Vitamin E visibly elevates hydration levels. Additionally, B-Group Vitamins support resilience and restore a calm appearance as redness and irritation are reduced.

Each day, we are exposed to the harmful impact of the sun's energy, which we refer to as the Solar Constant at RATIONALE. This energy comprises UV rays, visible light, and infrared radiation, all of which contribute to sun damage and many skin conditions. Safeguarding against the Solar Constant is crucial for maintaining skin health, preserving the skin's barrier function, and enhancing the effectiveness of the Formulations in our Rituals.

For continuous SPF protection, it is advisable to reapply every couple of hours throughout the day.

A lightweight hydrator is beneficial in the warmer climates for those experiencing an increased oil flow because of the humidity.

In the warmer months, The Cryogenic Resilience Facial soothes and calms the complexion of those experiencing signs of redness from increased temperatures. Alternatively, The Vitality Rejuvenating Facial restores a radiant complexion and visibly brightens an uneven skin tone.
