SkinCeuticals Phloretin CF is an advanced antioxidant serum for combination, discoloration-prone, and oily skin types — combining 10% L-Ascorbic Acid with 2% Phloretin and 0.5% Ferulic Acid for a broad-spectrum antioxidant formula uniquely suited to skin types that cannot tolerate the richer texture of C E Ferulic, while providing the additional brightening activity of Phloretin for discoloration-prone complexions.

Phloretin is a dihydrochalcone flavonoid derived from apple tree bark — a large-molecule antioxidant that provides intracellular antioxidant activity that small molecules like L-Ascorbic Acid cannot reach. It inhibits glucose transport into cells (reducing glycation), inhibits tyrosinase (reducing melanin production for brightening), and provides antioxidant activity at the cellular level. L-Ascorbic Acid (10%, slightly lower than C E Ferulic) provides collagen synthesis, antioxidant, and brightening activity. Ferulic Acid stabilizes and amplifies both actives' antioxidant effect. The lighter, alcohol-based vehicle is preferred by combination and oily skin types and for layering under oil-control products. 10× antioxidant protection vs. unformulated Vitamin C. Available at Beauty Riche — authorized SkinCeuticals retailer with same-day shipping.
