Let customers speak for us
Light as air…
Love this sunscreen…I forget that I have it on. No sticky feeling and no stinging as I also cover my eyes with it. Also no smell. Those were three major issues I have had with so many of the other North American or European sunscreens I have used in the past. This is my first time trying Korean products - I am impressed!

I use this on my face only and I love that it’s not oily and easy to apply
I use this on my face only and I love that it’s not oily and easy to apply. I’m not certain if it is a broad spectrum product as the bottle indicates SPF 50+ PA++++.What exactly does than mean for protection and UVA’s?

Perfect for oily skin or humid weather
I was really struggling to find a sunscreen that would protect without leaving a heavy feeling or just turning into a oily mess.
I truly recommend it, is light, doesn’t clog your pores and also leaves a nice soft texture without drying it either. I’ve been using for over 8 days and I can feel the difference.

New night product
I just recently started using Joseon products. This Dynasty cream is rich not too oily but you feel like your skin is getting all the good ingredients to get through the night. In the morning my skin feels soft and hydrated.
