my friend told me that coral calcium has helped her skin so i purchased it because i have some acne on my forehead. i have been using it for about a week and i havent really seen any results except my skin looks a little healthier. i also read online that a teenager with acne takes this and his acne cleared in about a week n 1/2. i would like to no if anyone has seen a difference in their skin from this and if so how long did it take to notice. Thanks so much
