In the series 5 Reasons: Why clean his face?
Reason #2: Eliminate makeup residue and excess sebum
The human body is so smart that it produces sebum to protect us. Sometimes, however, as during adolescence, during periods of stress (psychological or physical) or for not sure what reason, it produces surplus ... And the said sebum remains on the skin, mouths the pores, stimulates the appearance of pimples and disturbs us. Cleaning your face regularly (but not excessively) helps eliminate excess!
If you take the time to do makeup in the morning, try to take the time to remove makeup at night. A lot of facial cleansers are now formulated to get rid of your lipstick or foundation ... so no more excuses! Just like excess sebum, makeup can clog pores and cause several tanning problems. It should also be noted that many make-up products contain irritating ingredients, which should be removed every night!
