Hughes started his acting career in a public service announcement when he was 22 months old, and followed that up by appearing in his first feature film five months later. From his years as a child actor, Hughes was consistently one of the busiest young actors in Hollywood. He played Aaron Bailey on Full House from 1990 to 1995.
One of his first films was Jack the Bear, opposite Danny DeVito; in addition, he has starred on film in Pet Sematary (1989), Kindergarten Cop (1990), Apollo 13 (1995), Spawn (1997), Zeus and Roxanne (1997), and Mercury Rising (1998) alongside Bruce Willis. Hughes has also appeared in numerous television movies. He has been a series regular, recurring character or guest star on many television series including Baywatch (1989), Sister Kate (1989–1990), Beverly Hills, 90210 (1991) Full House (1992), Melrose Place (1992), Touched by an Angel (1994) and The Nanny (1994).
Hughes received an Emmy Award certificate for his participation as the voice of Tommy in the number-one-rated Fox animated television series Life with Louie (1995). His other voiceover credits include the voice of Clement, son of evil wizard Nostros (Tim Curry), in the 1996 animated Christmas special The Story of Santa Claus—also co-starring his fellow Full House recurring actor Kathryn Zaremba (Lisa Leeper) as know-it-all elf Aurora—as well as in the 1999 feature film Baby Geniuses, playing both twin babies, Sly and Witt.
Hughes appeared in a commercial for the video game Jaks. After a break in his career he re-emerged as a teen in the science-fiction hit Roswell. Hughes played a lovable villain who was part of a renegade group of aliens.
As a musician, he released two albums in 1995, when he was just 9. One is self-titled and the other is called "Halloween Haunts". Miko wrote songs for both albums and sings as well. They were recorded and released by his own company called Little Chief, Inc. In 2013, he directed the segment "See", in the horror anthology film Chilling Visions: 5 Senses of Fear.
Hughes was born in Apple Valley, California, the son of Mary (née Phelps) and John Hughes, a special effects technician (not to be confused with the famous 1980s–'90s director John Hughes). He has three siblings: Mike, Mitch, and Molly.
