Brightening Serum

Multi-Pathway Melanin Inhibition
for Age Spots, Sun Spots & Melasma.

Radiant Brightening Serum (formerly Bright White Serum) is Circadia's precision spot-brightening serum formulated for targeted correction of hyperpigmentation. ReguFade (Trans-Resveratrol) is a powerful skin brightener and antioxidant. BV-OSC (Tetrahexyldecyl Ascorbate) is an oil-soluble Vitamin C ester that is highly stable and reduces melanin synthesis. Phenylethyl Resorcinol (SymWhite) is a tyrosinase inhibitor, skin lightener, and antioxidant. Marrubium Stem Cell extract is rich in phenylpropanoids — forsythoside B and verbascoside — defensive molecules that protect the skin against oxidants and activate the skin's self-defense systems. Tyrostat-11 (Rumex Occidentalis extract) inhibits tyrosinase, limits tanning, has an anti-erythema effect, and supports age spot reduction. Vitamin E acetate is a powerful fat-soluble antioxidant that protects cellular membranes from free radicals.
