Do I like this product? Yes. Will I buy again? Yes. Would I consider it a "power serum"? Meh. I use this product every night after I get out of the shower and before bed. It is very lightweight and absorbs quickly, unlike most heavy/greasy night creams. Sometimes when I shower in the morning, I put it on before my makeup as well. I am 28 years old so while I do have a few forehead wrinkles, I do not have any deep wrinkles. This product hasn't done anything to "fill" or "reduce" them. Likewise, being only 28 I do not have anything to "firm, lift, and strengthen". What it HAS done for my face and neck is even my skin tone, moisturize, and smooth. I would definitely recommend this product. It is versatile, relatively inexpensive, and it is a staple in my skin care regimen.
