I am one of the women who have dry combination skin: ie, a shiny oily T-zone, the rest tends to be dry. Of course, then you do not even give a cream under the makeup .... That would make the whole thing even more greasy! After I tested by the Clinique Pore Minimizer and the silicon contained therein actually felt like a "carpet on the face," I had actually lost faith in Porenverfeinernde mattifying products. By the time of the Pore Refiner Bioderma came out. The product has once again to me so dearly loved "clean smell" and actually brushed the whole day. However, I use it in fact only for the T-zone, because the rest of my skin is rather dry. The product reduces moreover the formation of blackheads. The ingredients are also acceptable: salicylic acid to regulate keratinization, Laminaria (a type of algae) has anti-inflammatory, Polyporus officinalis (larch sponge) has an astringent and reduces the sebaceous gland secretion. Am only now bought a new pack with the product now after 4 months use still very satisfied and did. It keeps really long!
