Dermatiraelian plastiscine

From Memory Alpha, the free Star Trek reference

Dermatiraelian plasticine was a dermal regenerative agent used to maintain skin resilience after large-scale cosmetic surgery.

The fact that Aamin Marritza had taken large doses of the compound was part of the evidence that he had been surgically altered to resemble Gul Darhe'el in order to come to Bajor and expiate Darhe'el's crimes. (DS9: "Duet")
