Early days but pleased
I have only used the combo for a short time but I do like the products. I prefer products that are holistic without a lot of chemicals. As an older lady I have the lines of life’s experiences and I do sense a softening of upper lip lines so I look forward to further improvement.

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.
