Hi all. It's going onto 4 weeks now and my experience with the E. Ardin samples are really fantastic. I've had no irratation, redness. My make-up stays on all day and with a little touch up into the evenings too. I would definatley use these products. Since I've been using a proper skin care daily my skin is much better. I'm not even using half as much cover stick and foundation to cover up my pigmenation. Thanks to good skin products.
