Combination of retinol (pure vitamin A) and the fatty acid palmitic acid. Research has shown it to be an effective antioxidant when applied to skin. You may be surprised to learn that retinyl palmitate is found naturally in our skin, where it works as an antioxidant, particularly in regard to helping protect skin from UV light exposure—though it does not replace the need for sunscreen.
Reports that retinyl palmitate is not a safe ingredient are false. They’re based on a study from nearly 20 years ago that has never been reproduced or tested under real-life conditions such as how people use sunscreens that contain this ingredient. In addition, to date, there is no scientific evidence that retinyl palmitate is a carcinogen in humans. The safety of retinyl palmitate is supported by several accredited organisations and their opinions are widely available online. If you still have concerns, we encourage you to research the topic further.
