Caking on makeup for Fright Night and Monster-Mashing past midnight is sure to leave your derm' in distress come Nov. 1. Bacteria gets stuck in pores with all that facepaint, junk food and alcohol, and there's a good chance you didn't drink enough water to flush out toxins. So baby your biggest organ and consider these routines your post-Halloween hair of the dog.

1. CLEANSE

Your skin's biggest foe is bacteria trapped under makeup and sweat. Water won't penetrate oily makeup, so swipe it off for good with jojoba oil, which is full of vitamin E and prevents damage from free radicals. Then, scrub your pores clean with a good exfoliant.

2. REJUVENATE

Drink lots of water and antioxidant-rich beverages like green tea and fruit juice. This will not only flush out toxins but also transports vital nutrients to cells, crucial for healthy skin. Then, take your vitamins through a topical treatment.

Bet you've never enjoyed getting over a hangover until now.
