Manuel Gutierrez (born April 4, 1991), known professionally as Manny MUA, is a make-up artist, YouTuber, and beauty blogger. He is the first male brand ambassador for the make-up brand Maybelline. He is the founder and owner of the cosmetics brand Lunar Beauty, and has a social media presence that includes 4 million subscribers on YouTube and over 4 million followers on Instagram

Gutierrez grew up in a Mormon family and has two younger brothers.

Before deciding on a career in beauty, Gutierrez planned to attend medical school with aspirations of becoming a plastic surgeon. He has a Bachelor's degree from San Diego State University

Gutierrez first became interested in make-up after watching his mother do her make-up during his childhood. He later worked at Sephora and MAC. He began his YouTube channel in 2014. He regularly posts make-up tutorials, make-up first impressions, and beauty tips. He has collaborated with Makeup Geek on an eye-shadow palette, Ofra Cosmetics on lip products, and Jeffree Star Cosmetics on two highlighters and 2 lipsticks.

In 2017, Gutierrez and fellow YouTuber Shayla Mitchell were announced as brand ambassadors for Maybelline, specifically Colossal Big Shot Mascara. He is the first male brand ambassador for the brand. He is the second male to be chosen as a spokesperson for a beauty brand after James Charles who had been previously announced as a spokesperson for CoverGirl in October 2016. Later that year, Gutierrez and his ex-friend Jeffree Star announced a collaboration for Star's make-up brand to debut in April. After the announcement, Black Moon Cosmetics sued the duo for copyright and trademark infringement alleging that they had copied their logo without permission. The lawsuit was later resolved. In April 2017, Gutierrez was the only male to make People magazine's annual "Most Beautiful" list. In 2018, he was named to Forbes' annual list of "30 under 30" in the Arts and Style category. In 2018, Manny appeared in season three of Escape the Night as the Record Producer.
