GOOD FOR

Dull or uneven in tone — sun damage, general flatness / Wanting antioxidant protection alongside SPF in the morning / Using the RATIONALE routine and building from #1
HOW TO USE

Apply after #1 in the morning. Follow with #3 The Brilliance Tinted Serum SPF50+ as the final step. Part of the RATIONALE AM routine: #1 → #2 → #3.

The antioxidant step in the RATIONALE morning routine. Where most Vitamin C serums rely on a single form of ascorbic acid, #2 The Brightening Serum layers multiple stabilised Vitamin C forms — ascorbyl tetraisopalmitate and sodium ascorbyl phosphate — alongside glutathione, ubiquinone, tocotrienols and lycopene from tomato seed oil. The result is broader antioxidant defence against oxidative stress, not just the brightening work of Vitamin C alone. Also contains retinol at a low concentration — making this an AM serum that does more than it advertises.
About the brand

RATIONALE is a cosmetic chemistry-led skincare range built around six pillars of skin health — not six hero ingredients, six complete formulations. Each product is designed to do multiple things at once, addressing a skin goal from every angle rather than making you layer five products to get the same result. Created by a cosmetic chemist, the range is structured as a full routine: #1 through #3 for the morning, #4 through #6 for the evening. Simple in concept, serious in results.
