Circadia Radiant Brightening Serum
Target your dark spots directly — and watch them fade. The Radiant Brightening Serum is a potent, concentrated evening treatment serum that goes straight to work on stubborn hyperpigmentation, age spots, sun spots, and melasma — delivering a sophisticated trifecta of brightening actives that inhibit melanin production, protect against new discoloration, and visibly illuminate the complexion from within. Applied directly to affected areas in the evening when the skin is most receptive and in active repair mode, this serum delivers targeted correction where you need it most.
Key Actives & What They Do:
-
ReguFade (Trans-Resveratrol) — a potent antioxidant and powerful skin brightener that visibly reduces pigmentation while simultaneously protecting against the oxidative stress that triggers new melanin production — correction and prevention in one ingredient
-
BV-OSC (Tetrahexyldecyl Ascorbate — Oil-Soluble Vitamin C) — a highly stable, oil-soluble form of Vitamin C that penetrates deeper than water-soluble alternatives, reducing melanin synthesis, brightening existing discoloration, and delivering lasting antioxidant protection
-
SymWhite (Phenylethyl Resorcinol) — a clinically proven tyrosinase inhibitor, skin lightener, and antioxidant that effectively reduces discoloration and improves overall skin clarity — clinically shown to be more effective than kojic acid
-
Marrubium Stem Cell Extract — rich in phenylpropanoids including forsythoside B and verbascoside, this stem cell extract protects the skin against oxidants and activates the skin's natural self-defense systems against further pigmentation
-
Tyrostat-11 (Rumex Occidentalis Extract) — inhibits tyrosinase, limits tanning response, reduces erythema, and provides targeted age spot reduction for comprehensive pigmentation correction
-
Vitamin E (Alpha-Tocopheryl Acetate) — a powerful fat-soluble antioxidant that protects cellular membranes from free radical damage that triggers melanin overproduction
Key Benefits:
- Inhibits tyrosinase and slows melanin production at the source
- Visibly brightens the appearance of age spots, sun spots, and melasma

0.5 oz
How To Use: In the evening after cleansing, apply a drop onto fingertip and apply directly to affected areas only. Avoid contact with eyes.
Best For: Age spots, sun spots, uneven pigmentation, and post-pregnancy melasma — and anyone with stubborn targeted discoloration that needs concentrated, direct treatment rather than an all-over approach
Recommended For:
- Age spots
- Sun spots
- Uneven pigmentation
- Post-pregnancy melasma
✨ Pro tip: Because this serum is designed for spot application rather than all-over use, it's highly concentrated and extremely targeted — use the very tip of your ring finger to apply a tiny amount directly to each dark spot or area of discoloration for precise delivery. Consistency every evening is what delivers the most dramatic results — brightening is a cumulative process and skipping applications significantly slows progress.
