Abstract
The conventional comedone extractors available are not able to evacuate contents properly, because of their vertical pressure. So, the comedone extractor which can exert pressure simultaneously in vertical and oblique direction for complete evacuation is the need of the hour.

PROBLEM
Comedones are elongated or oval keratinous plugs that reside in the elongated pilosebaceous canals in seborrheic areas of body which are more commonly open at an angle of 20–30 degrees to perpendicular axis (rather than vertically).[1] Disposable syringe was used earlier vertically for extraction of contents of comedones from cysts.[2] For proper extraction of keratinous material of comedones, there is a need for an elongated or oval comedone extractor that should be pressed and dragged in an angulated manner instead of only pressing vertically over the lesion.[2] Therefore, we advise the use of a modified needle hub of a disposable syringe for better extraction of contents of acne comedones.
SOLUTION
We took a disposable syringe (3 ml) and sliced its needle hub smoothly with a sterile surgical blade at an angle of 30–45 degrees (which can be less but not more than 45 to lessen the pressure trauma over the site) to make its punching end slightly inclined so that the surface of the punching end (i.e., rim) is oval to elongated in shape [Figure 1]. The comedones, papules, pustules (and small nodules) were opened/dilated under aseptic conditions with a hypodermic needle as standard procedure. Then the modified syringe is placed over the lesion, keeping its opening within the rim of the punching hub. With the syringe in place, the lesions are pressed with this syringe, and dragged [Figure 2 and Video 1]. There is no incidence of prick or puncture injury and post-inflammatory hyperpigmentation. During the procedure, bleeding is less and if it is there, it should be hemostasised as soon as possible to avoid post-procedure hyperpigmentation.
