"Cambia la Piel" (English: "Skin Changes") is the fourth and final single from Ricky Martin's second English-language album, Sound Loaded (2000). It was released as a promotional single in Spain and Latin America on October 15, 2001.

"Cambia la Piel" is a Spanish-language song written by Pau Donés Cirera, leader of the Spanish rock group Jarabe de Palo. It was produced by Martin's collaborator, K. C. Porter. Thanks to "Cambia la Piel" (among few other tracks), Porter won the Latin Grammy Award for Producer of the Year at the Latin Grammy Awards of 2001. "Cambia la Piel" was released as the fourth (promotional only) single from Sound Loaded in Spain and Latin America on October 15, 2001.

Sal Cinquemani from Slant Magazine wrote that adding a Spanish-language original song "Cambia la Piel" to Sound Loaded was a good idea. He noted that Martin is better off singing in his native tongue, where his vocals seem more natural and less contrived. Jose F. Promis from AllMusic called it a sizzling track.
