I’m serious when I say if you don’t use any k skincare.. you HAVE to try this one. It’s an all in one product and targets many concerns and issues in one go. At least for me. I have rosacea and very dry, sensitive skin and this soothes my skin like no other!! It reduces redness.. helped to get rid of my acne. hydrates my skin and makes my skin tone even in better texture.
