Dermelastic contains a special synergistic blend of extracts that will tighten the skin, get rid of stretch marks, discoloration and scars. Your serum contains 2.5 of Dermelastic extract making it extremely effective and strong. This is the maximum that we seen can be used without losing the efficacy of the serum. Meaning to much more will not make anymore difference. Your body can only adjust so much in a short period of time. It is recommended you use this once a day for two weeks to see dramatic changes, but after the first dosage you will notice a significant difference.
