3-O-ETHYL ASCORBIC ACID
Also known as: Et-VC
CAS Number: 86404-04-8
Key Benefits
Stable multifunctional Vitamin C — superb whitening, boosts HA production & collagen synthesis, protects from UV + blue light + pollution
How It Works
Inhibits tyrosinase & TRP-2 to block melanogenesis. Stimulates collagen & hyaluronic acid synthesis. Scavenges reactive oxygen species after UV exposure.
Why BP Derma Uses It
We chose 3-O-Ethyl Ascorbic Acid as our primary Vitamin C form because it is dramatically more stable than pure ascorbic acid — no yellowing, no oxidation. It delivers the full antioxidant and brightening benefits of Vitamin C while remaining effective throughout the product's shelf life.
