UC Irvine dermatologist Dr. Christopher B. Zachary recommends using a good moisturizing lip balm with sunblock. Check out: Neutrogena Lip Moisturizer SPF 15 ($3.59 at Longs Drugs).
Lip exfoliants can help slough off the dead skin on chapped lips for quick skin rejuvenation, said makeup artist-esthetician Anastazia Grey Woodin. Use an exfoliant weekly for about five minutes, but don't use it if your lips are so chapped they hurt. Check out: Smashbox Emulsion Lip Exfoliant ($18, Sephora).
For those pesky cold sores, Woodin recommends applying Abreva ($18.99, Longs Drugs) at the first signs.
