I simply cannot say enough about this product. It has literally taken years off my face, both in terms of reducing the appearance of lines and of evening out my skin tone. After just one day I could feel the plumpness and elasticity of my skin improve. It's almost miraculous and inexpensive to boot! I now use both the serum and the moisturizer and have recommended it to all my friends in my age group (early 40s). Many have tried it, all were equally amazed. Read up on this one- it's not another gimmick, the science behind the formula is sound. Easily my best skincare find ever.
