For the face, favour the cleaning technique wherever possible.

Blackhead acne is perhaps the easiest type of acne to squeeze, as its waxy nature means it often comes out as one piece and leaves a fine seal inside the skin which significantly restricts any bleeding - so much so that a small hole into the skin can sometimes be seen after the blackhead comes out.

Using at least one finger/thumb nail is preferrable.

Get enough of the skin around the blackhead so that the squeezing pressure is applied under the visible top.

Remember, pain IS part of this process, especially when the zit (rapidly) exits the skin - so when you're ready, squeeze firmly with increasing pressure as needed.

Blackheads usually exit with a rapid wriggle motion.

When the blackhead comes out, squeeze it between two finger/thumb nails to understand the feel of the gunk that it is - as similar but smaller amounts of this type of gunk can often form further below whiteheads.

Apply a dressing if required, but just keeping the surface clean will often allow the resulting small hole to heal rapidly enough.
