The first five thousand (5,000) entrants will receive a free Neutrogena Healthy Volume Mascara.

This giveaway begins on September 13, 2011 and ends when all 5,000 mascaras have been distributed, or on October 17, 2011 at 11:59 p.m. ET, whichever occurs first. Once all the mascaras have been distributed, there will be no substitute prizes. Since these giveaways usually reach the maximum number of eligible entrants in the first few hours after they go live, it's advisable to enter as soon as possible.
