Generally, lip gloss wouldn't be too nourishing or mosturizing for your lips.
(Don't do this if your lips are raw). You can make a great lip exfoliant by mixing a small amount of sugar and honey to create a gritty substance. You want to apply this to the lips, and gently scrub in a circular motion. A less messy way to rid the lips of dead skin is to also scrub with a damp cloth or rag.
After exfoliating your lips, you'll want to apply a bit of lip balm/chapstick to the area to protect your lips from the cold, the wind, etc. Re-apply as needed.
*One thing to make sure of is that you get enough water to make sure your lips, and body, are hydrated.
