Unless your conversion rates are sky-high, it's very tough to use PPC to sell products under $20. You could try to up-sell or cross-sell, this might bring you into the black. Or obviously, bid really low at the expense of course of less traffic.

You say make up products? A site targeted content network campaign might work for you. I suggest you increase your budget however. And obviously, improve your quality score so that your cost per click gets lower.
