My skin has recently become really dehydrated..and this has cured it..I think!! (I tried hydrating masks but I needed something I could use everyday)It's a blue serum and all you need is a couple of drops..you can even take it over the eye area...the fine lines I had dissapeared within the day.I'm not sure how this would work on long standing lines and wrinkles but for ones caused by lack of moisture this worked for me. I've only had it for a week so if things change I'll update you!It is quite expensive but I think I won't need to use it as often now that my skin looks and feels better.
