I think its really hard to find reputable information on wrinkle products and their ingredients in the internet... why? because, every company is trying to push their own "revolutionary" ingredient/product. So what they do is start posting negative "Research" about their competitors in order to get people to buy into theirs instead. In my opinion, its best to stay away from all these chemicals and antiwrinkle creams. Most of them have not been tested for long term safety and you really dont know what will happen to your skin in the long run. The best thing is to just make sure you use proper sun protection and keep your body hydrated and nourished with proper foods and plenty of water. This will make the biggest difference in your skin, trust me! I've gone through so many creams, potions, treatments and now all I do is leave my skin alone and just maintain a good diet. My skin now looks great (for my age)!
