I have purchased this colorescience flex several times now from Joy Viva. It’s my favourite tinted sunscreen. It’s creamy and smooth. In winter I use the fair and in summer I mix the medium with the fair. I have also purchased the glow. Sometimes I’ll mix the glow with the flex to get a luminous look. You can apply this very thinly or you can apply it thick. It looks good both ways. You can just re apply over the old layer as well. It looks good. I get no irritation at all with this product. You can build it up as well too if you want more coverage over certain areas. I also use retinol and I find this product does not dehydrate my skin.
