Second Skin (Spanish: Segunda piel) is a 1999 Spanish romantic drama film directed by Gerardo Vera, starring Javier Bardem, Jordi Mollà, Ariadna Gil and Cecilia Roth.

Elena and Alberto, a couple from Madrid, have a happy marriage, professional success and a loving son.

However, Elena later finds a hotel receipt in Alberto's pocket and discovers that he has been unfaithful to her.
