4th Impact is a Filipino P-pop girl group consisting of four sisters, Almira, Irene, Mylene, and Celina Cercado, originally from Santiago City in the Philippines. Active since the early 2000s under several names, including Cercado Sisters, MICA, and 4th Power, the four performers gained international recognition in 2015 through their appearance on the British television competition The X Factor, where they finished in fifth place. Blending contemporary pop, R&B, soul, and dance-pop influences, the group stands out for its powerful vocal performances, sophisticated harmonies, and interpretations of popular songs. Following “Unleash the Diva,” 4th Impact developed its own repertoire with tracks such as “K(No)w More,” “Here We Go,” “Tapat Sa'yo,” “Distorted,” and “All At Once.” Its self-titled debut EP, released in 2024, marked a new artistic chapter, followed by the single “I Bet You Never” in 2025. In April 2026, the four sisters adopted the name 4Sisters to reconnect with their family roots and pursue a more personal musical expression. Through their international journey, vocal abilities, and perseverance, they have contributed to the recognition of Filipino pop music beyond its national borders.
