You can save your $30 and spend the money on something more usefull like say a new top?
Here's how: just add a dash of sugar to olive oil and massage lips, concentrating on rough patches.
I'm sure you've heard lips need sunblock too. My favorite beauty product for my lips isn't lipgloss or long lasting lipstick. It's Blistex Silk & Shine. It a glossy, ultra moisturizing lip balm that gives a very natural look. This + some eye make up, and I'm out the door.
Super-Silky Lips: Silk & Shine feels satiny soft going on and leaves
your lips feeling that way. Silk Extracts, special moisturizers and vitamins A,
B5 and E help create a silky texture that makes lip surfaces smooth and supple.
It feels great!
A Touch of Shine: Silk & Shine imparts a touch of sheer
gloss to the lips for a healthy, finished appearance. Your lips will look as
good as they feel. (source)
