The number of different skin care brands available is astronomical! What do you buy? There are so many great brands and even more not as great brands, how do you know what to choose?
My first suggestion is see your aesthetician, they have trained to know how to help you with your skin goals as well as countless hours of experience with different products, actives and other ingredients. They will also have higher amounts of the active ingredients you need than in the OTC choices in the mall or drugstore. Usually these professional products don't even cost any more in the long run. Many spas will be happy to recommend a good regimen with a free skin consultation to get you on the right path.
