Learn more about GlycerinTocopherol (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.

There are often claims that Vitamin E can reduce/prevent scarring, but these claims haven't been confirmed by scientific research.

It’s my first Korean sunscreen and I am an amazed. It feels so much better on my skin compared to European sunscreens. I have acne-prone skin and this sunscreen without niacinamide is so light and fluid. It smoothes my skin and gives the effect of second skin. It is not sticky nor gives a oily effect.
ok, i knew i’d love this, but still… how did they make such a lightweight sunscreen without either alcohol or dimethicone? it’s even more lightweight than the SKIN1004 blue pump sunscreen. zero white cast at all (granted, i have fair skin), and absorbs just as quickly as any alcohol sunscreen. LOVE IT!
however, the only bad thing is that it’ll pill when i also use SKIN1004 Poremizing Ampoule. so Show more
