Take care of your lips by keeping them moisturized, and using an SPF 15 or higher lip treatment when you'll be in the sun. You can exfoliate lips once per week with a soft toothbrush and use a product like Blistex DCT overnight to improve the overall health of your lips. Finally, smoking is a habit that can wreak havoc on your lips, causing premature wrinkles and discolorations. Having healthier, more beautiful lips is just one more reason to quit!
