The Brilliance Collection

What is The Brilliance Collection?

The Brilliance Collection is the third of our daytime essential collections, offering skin nourishment and solar and environmental protection, inspired by Zinc Fusion Technology. Each formulation combines Zinc Oxide with Iron Oxides, Melanin, and antioxidant Multi-Vitamin Complexes to defend against UVA, UVB, blue light, and environmental aggressors. The Brilliance Collection is the final and non-negotiable step in every RATIONALE daytime ritual.

What is Zinc Fusion Technology?

Zinc Fusion Technology is RATIONALE's proprietary system for delivering elegant, broad-spectrum sun protection. It blends Zinc Oxide — a mineral filter that physically reflects UV radiation — with Iron Oxides for visible light defence, alongside antioxidants that neutralise free radicals. The result is a luminous, weightless finish that protects without the white cast traditionally associated with mineral SPF formulations.

What is the difference between SPF15 and SPF50+ formulations?

SPF15 offers daily protection suitable for low UV environments or indoor-led routines, while SPF50+ delivers maximum broad-spectrum defence recommended for outdoor exposure, the Australian climate, and skin actively addressing pigmentation. For most clients, we recommend #3 The Brilliance Tinted Serum SPF50+ as the standard daily formulation, with #3 The Brilliance Enriched Crème SPF15 as a hydrating complement.

Why are Iron Oxides included in Brilliance formulations?

Iron Oxides offer visible light protection, particularly against blue light from screens and high-energy visible light, which has been shown to contribute to pigmentation and oxidative stress. Their inclusion also delivers a luminous tinted finish that adapts to a range of skin tones, providing both complexion-perfecting and protective benefits in one formulation.

Is Zinc Oxide better than chemical sunscreens?

Zinc Oxide is a mineral filter that sits on the skin's surface and physically reflects UV radiation, rather than absorbing it. It is generally considered well tolerated by sensitive skin and offers immediate broad-spectrum protection on application. RATIONALE has chosen Zinc Fusion Technology as the foundation of our Brilliance Collection for its efficacy, calming properties, and elegant sensorial finish.

Can I wear Brilliance formulations under makeup?

Yes. The Brilliance Collection is formulated to layer beautifully beneath cosmetics, with #3 The Brilliance Tinted Serum SPF50+ also serving as a luminous tinted base. For seamless integration with makeup, allow the formulation to settle for one to two minutes before applying additional products. The Beautiful Collection offers complementary SPF colour formulations created to layer over Brilliance.
