Best Brown Mascara Guerlain Noir G Volumizing & Curling Mascara (£32) "Not only did this Guerlain product make me a fan of brown mascara again but the formula is next-level. As I do, I forgot that I had it on multiple times when wearing it and touched, rubbed, and tugged at my lashes. It doesn't budge one inch. 10/10 from me." — AB Image Source: nordstrom.com
