If your lips are dry or chapped, then an overnight lip therapy is what you need for your lips to be moisturized as well as hydrated.
Specially if you tend to wear lip products all day then the lips have to be treated with care at night for it to be soft and smooth.
Exfoliate your lips gently with a tooth brush to remove any dry or dead skin, follow with extra virgin coconut oil or sweet almond oil before going to bed to wake up to soft baby lips.
To treat your lips on the go, fill a roll on travel size container with coconut oil to keep your lips soft and smooth all day long. Also, to keep your lips in the best shape through out the year, opt for a lip balm with SPF before stepping out.
