Brightening AHA & Vitamin C Serum

Brightening AHA & Vitamin C Serum
A dedicated brightening treatment — Alpha Arbutin, Kojic Acid and Mandelic Acid work alongside Vitamin C to target the look of pigmentation and uneven tone, in one focused serum step.
Key Ingredients
Formulated with Alpha Arbutin, Kojic Acid, Mandelic Acid and STAY-C (Sodium Ascorbyl Phosphate) — a considered blend of AHA exfoliation and Vitamin C brightening technology. Full ingredient detail is available in the Ingredients tab below.
Why These Ingredients?
| Ingredient | Why it's here |
|---|---|
| Alpha Arbutin | A gentle brightening ingredient widely used in skincare formulations to help support a more even-looking skin tone. |
| Kojic Acid | A brightening ingredient often used alongside other tone-evening actives, commonly found in pigmentation-focused formulas. |
| Mandelic Acid (5%) | A larger-molecule AHA, generally considered gentler and slower to penetrate than smaller AHAs like glycolic acid — often chosen for a more gradual approach to exfoliation. |
| STAY-C (Sodium Ascorbyl Phosphate, 5%) | A stable, water-soluble form of Vitamin C, well suited to serum formulations. |
How to Use
Apply to cleansed skin, in the morning or evening. As with any AHA exfoliant, we recommend daily SPF during the day.
Where It Fits in Your Routine
Day Bright is a targeted brightening step — apply after cleansing and before your moisturiser. If you're also using Barrier B or Retinol Peptide Complex, introduce actives gradually and patch-test first.
Day Bright and Royal Oil C both bring Vitamin C into your routine, but they're built for different moments. Day Bright is an AHA exfoliating serum, formulated to visibly even tone and reduce the look of pigmentation. Royal Oil C is a nourishing Vitamin C treatment oil, with no exfoliation. Many customers choose the one that fits their skin, or use both — Day Bright as an active step, Royal Oil C as a nourishing finish.
