Antioxidant
Effect
An ester of retinol (bound to a fatty acid).
Concentration
The EU limits it to 0.3% RE in face and other products (about 0.55% as retinyl palmitate) and 0.05% RE in body lotion (2024/996). Japanese quasi-drug cream precedent: 30,000–250,000 IU/100 g (about 0.017–0.14%).
Effect
An ester of retinol (bound to a fatty acid).
Mechanism
Three-step conversion to active form, weaker but less irritating
Typical concentration
The EU limits it to 0.3% RE in face and other products (about 0.55% as retinyl palmitate) and 0.05% RE in body lotion (2024/996). Japanese quasi-drug cream precedent: 30,000–250,000 IU/100 g (about 0.017–0.14%).
