I used to change my body cream on monthlyBasis, I hardly finish a cup of cream because I have a hard skin that hardly respond to creams so if dont get my desired results after two to 3 weeks I dump them and go for another type but since I started using zinnyt product for the past 11 months I have not changed to another cream.Zinnyt product is the best I have ever used and its good for my skin, I now look younger and beautiful, I also stop wearing makeup because my skin is glowing and I feel ok without makeup.
