I am now on my fourth week using the Garnier product. The dark marks on my face have lightened and looking better but are still visible without foundation. The mark on my forehead is still not lightening at all. I am happy with the way my skin is looking at the moment. The pores are nice and refined, skin is looking bright, glowing and moisturized. Will continue using the product in the hope that prolonged use will eventually make the persistent marks dissappear!!
