Here is an easy way to freshen up your face by Monday.
Every time you jump in the shower this weekend... apply a hydrating mud masque. Put it on a few minutes before you hop in the shower...and wash it off last. The steam from the shower will open up your pores for better hydration. Then, each night give yourself a good exfoliation before you go to bed.
By Monday... you should notice a more hydrated and vibrant you in the mirror.
