Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Tocopherol (also known as Vitamin E) is a common antioxidant used to help protect the skin from free-radicals and strengthen the skin barrier. It's also fat soluble - this means our skin is great at absorbing it.
Vitamin E also helps keep your natural skin lipids healthy. Your lipid skin barrier naturally consists of lipids, ceramides, and fatty acids. Vitamin E offers extra protection for your skin’s lipid barrier, keeping your skin healthy and nourished.
Another benefit is a bit of UV protection. Vitamin E helps reduce the damage caused by UVB rays. (It should not replace your sunscreen). Combining it with Vitamin C can decrease sunburned cells and hyperpigmentation after UV exposure.
You might have noticed Vitamin E + C often paired together. This is because it is great at stabilizing Vitamin C. Using the two together helps increase the effectiveness of both ingredients.
There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

I applied a small amount to a dark spot. The next day I woke up with an inflamed cystic acne that just appeared out of nowhere. Looking at the ingredients now I am not surprised. Very disappointing, why do they make formulas like this???

Love it! Use it every evening and find it to be super hydrating.
If you are okay with oils, are on the dry side and don’t like the feeling of squalane - this will change your life. I use it on the occasions when I want an occlusive, a product that you use last in your routine to help retain moisture in your skin. Has definitely strengthened my skin barrier, doesn’t irritate.
