Skin care has become more complicated then it was even 10 years ago so it can get confusing trying to figure out how to use them. I have been asked several times on when you should apply your serums, after you wash and dry your face you should apply your serums. Serums can be layered and it doesn't have to be in a specific order but don't forget your neck and d?colletage. Then you can apply your moisturizer for best results let them soak in before each application.
