Manuel Gutierrez (born April 4, 1991)  , known professionally as Manny MUA , is a make-up artist, YouTuber, beauty blogger, and beauty influencer.  He is the first male brand ambassador for make-up brand Maybelline.   He has a social media presence that includes 4 million followers on YouTube and over 4 million on Instagram. 
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 and Ofra Cosmetics on lip products. 
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 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. 
Gutierrez grew up in a Mormon family and has two younger brothers.   He identifies as gay  and has described being sent to therapy as a teenager to "reverse the effects of being gay", though he was allowed to stop after six months as he became depressed during the ineffective treatment.  
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.
