There are plenty of good products out there. One should change their skin care routine every six months or so. If you use the same cream for a very long time it will stop working. The same is with shampoo. Many people use two or three different shampoos and just rotate them. It works well. The same should be done with skin care products. For example, you can use a different brand of face wash than your cream or serum. Many products are made to be used with different products.
