I decided to try silicon modelind gel, because I had heard about its natural components from my friend and I loved the word ‘silicon’. Also they told that It had been checked by successful medical practice for many years.. So i took it! My skin welcomed this gel with absence of allergic reaction, face was glad and became much better after using the gel. This gel has a nice smell, a lot of vitamins. So I am using it for some years and I haven’t seen any bad sides. I advice this gel to everybody, because it's a real help for aging skin. I feel myself better and several decades younger.
