I'm a big fan of Peace Keeper's 73% organic lip balm, which has a tingly mint flavor. I really like their natural nail polish too, especially when they periodically offer BOGO deals. Plus, they give all their after-tax distributable profits to women's health advocacy and human-rights issues, and their products are slave-labor-free, fair-waged, no-animal-testing, and they offer vegan products. You don't even have to try to rationalize a beauty spree here - it justifies itself!
Just in time for Mother's Day, you can try their new "Perfect As Is" lip balm, which is 75% organic and is made with natural rose flavor, stevia, and a bunch of natural oils. The lip balm is .25 oz, which is almost twice as big as your standard lip-balm tube, and with promo code MomPK09 it's a BOGO offer. Plus, when you order three, you get free shipping, so throw one of their Eco-Sensual lip balms in your cart and you're good to go (I think that's cheaper than shipping would be, anyway).
If you're stumped for a pretty, karmically sound Mother's Day gift, look no further!
