While I adored my mascara, it didn't do much more than make my lashes somewhat darker. However, with very sensitive eyes, that's usually a problem. After going through 12 others that either clumped or irritated my eyes, I read the reviews on this one and decided to take the chance after spending over $100 on other brands. What a difference! length and volume without any redness or irritation! I get two months out of each one, which is plenty for me.
