Have you ever stopped to consider the number of advertisements that are directed to you everyday about how you look? Some day when you get up start keeping track of the number of commercials and printed ads you see that involve a health or beauty product. The television, radio, newspapers and billboards are filled with advertisings ways that you can look and feel better and younger.
So, it really comes to rephrasing the question to - 'What is the best skin care product for me'. Yes, this is exactly the question that you should be asking, and unfortunately there is no easy answer for this. Arriving at the best skin care product for self will need some effort on your part.
I have found that as long as I am consistent in using any product they all work about the same. If I do a good job of washing my face and putting on a moisturizer before bed and then put on another application of moisturizer under my make up in the morning, my skin looks and feels good. Occasionally I will use a peel off masque to remove dead skin. I have found that the more lotions and potions I expose my skin to the drier it gets.
I believe that if they would have taken any product and used it faithfully they would have the same results. As long as you avoid harsh chemicals, which hardly any skin care products contain, you are going to get similar results from the various products. I find that if I find a lotion that I like the smell of I am more apt to put it on after my shower to help keep my skin soft. Our skin is the largest organ we have. It pays to be good to it and to keep it healthy. The best skin care product that we can use on a daily basis is protection from the sun. Sun damage not only weakens the skin but it ages it and may cause cancer. Protecting your skin from the sun and cleaning it on a daily basis will help to keep you looking good.
Note that the best skin care product cannot be determined overnight. It's only through experiment (and awareness) that you can find the 'Best skin care product' (for you).
