5. Use petroleum jelly throughout the day.
Petroleum jelly is an affordable, readily available balm for chapped lips. Scientists recommend daily application for optimal results. It seals in moisture longer than oils and waxes. Apply a layer during the day and a thicker coat before bedtime. This allows the petroleum jelly to work its magic overnight, locking in hydration. You’ll wake up to soft, smooth lips with restored luster and shine. Let petroleum jelly deeply replenish your lips while you sleep.
