Whether you add anything after 'explicita' is a question of whether you think it is needed. In English explicit by itself is a vague term so maybe just leave explicita, but I would put inverted commas around it.

Parental Advisory is a message affixed by the Recording Industry Association of America (RIAA) to audio and recordings in the United States containing excessive
use of profane language and/or sexual references. Albums began to be labeled for "explicit lyrics" in 1985, after pressure from the Parents Music Resource Center (PMRC). In 2000, the PMRC worked with the RIAA to standardize the label, creating the now-familiar black and white design.
