It is an absolute must to go to sleep with a clean face. At night your skin repairs itself and if you leave your make-up on it just sinks deeper into your pores causing breakouts and dull looking skin. When night time hits though, it can get really hard to drag yourself to the sink or your vanity for a little TLC on that gorgeous face of yours. My suggestion would be to not wait until the end of the day to do your night time skincare routine.
Wash your face with clean hands when you get home from work/school or right after dinner. It is also best to apply any night time creams at least an hour before you go to bed so it has some time to seep into your skin as opposed to applying your creams and having them wipe away on your pillow.
Hope this little tip helps with your beauty sleep!
