Sonic lipstick

The sonic lipstick was a device similar to the sonic screwdriver owned by the Doctor, and regularly employed by Sarah Jane Smith. It resembled a genuine 21st century lipstick closely enough not to seem suspicious.

History
Almost certainly created for Sarah Jane by the Tenth Doctor, one account indicates that he had left the sonic lipstick for Sarah inside a sliding panel on the side of K-9 Mark IV. (WEB: bbc.co.uk)

Following the destruction of one of the devices by Sontaran Commander Kaagh, Sarah Jane later produced another. (SJA: Enemy of the Bane) The Doctor may have created two for her, or she may have built a duplicate of the one she had with help from Mr. Smith and/or K9. Although primarily used by Sarah Jane, it was also seen to have been used by the Doctor, Luke, and Rani. (SJA: The Empty Planet)

Features
The sonic lipstick looked like a normal lipstick on the outside. The lid came off and it twisted to reveal the emitter. When in use, the sonic lipstick generated a pinkish-red light, and produced several sounds. Like the Doctor's sonic screwdriver, it also remained ineffective against deadlock seals. The Slitheen described it as a sonic disruptor, (SJA: Revenge of the Slitheen) and Sarah Jane once threatened to destroy a talisman with sonic disruption. (SJA: Eye of the Gorgon) It ran on some sort of energy which could run out. (SJA: Death of the Doctor)

Mark I
Although there were known to be two distinct sonic lipsticks carried by Sarah Jane, the two units coexisted for an unknown length of time. As a result of this coexistence, it is unknown which particular unit was used in any given occurence prior to the destruction of the one. (SJA: Enemy of the Bane)

Mark II
The Mark I was destroyed by commander Kaagh standing on it. (SJA: Enemy of the Bane) Shortly thereafter, Sarah Jane Smith revealed another sonic lipstick in her bag, using it to destroy the Tunguska Scroll and indicating that a girl can have more than one lipstick. It's unknown if the Doctor built more than one or if Sarah (perhaps with the help of K-9 or Mr Smith) made a duplicate.

Behind the scenes

 * Character Options released a sonic lipstick replica featuring lights and sounds. The toy was slightly different from the original, in that the ridges in the actual prop are less deep and the coat was shiny metal rather than bland brown plastic (SJA: Revenge of the Slitheen, The Last Sontaran)
 * The origin of the sonic lipstick, while given on the SJA website, is not mentioned on screen. The closest reference occurs in Invasion of the Bane when Sarah Jane invokes the Doctor's name when using the device.
 * The sonic lipstick made its one and only appearance in Doctor Who in DW: Journey's End.
