Lip gloss and Chapstick (a popular brand of lip balm) serve different purposes. Lip gloss is primarily used to add shine and sometimes color to the lips so they look shiny and full. The chapstick or other lip balms are prepared to moisturize, protect, and heal dry or chapped lips. If you want hydration and protection, a lip balm like Chapstick is better. To give more enhancement to your lips with shine, lip gloss is the way to go.
