YASSSSS!! this is the lip conditioner you're looking for. Colorado is tough on skin in general and lips especially, mine have been rough and unhappy for too long and this MAC lip conditioner seriously turned them around. With just the right consistency to penetrate and protect without being greasy, sticky or smelly - it's legit the best I've ever used and worth every penny.
My lips are very dry especially during the Summer months (weird, I know), but this is the best lip conditioner that I have tried and I've tried a lot from high-end to low-end brands. It's very moisturizing without being sticky. Right now I have 5 of these, 1 for my purse, 1 for the bathroom, 1 in my night stand and 2 for back ups. I love this and I hope MAC doesn't decide to pull the plug on it.
