Cane marks on a man's bottom.
Tawse marks on a man's bottom

Marks on the skin are visible traces of physical impact. Spanking with implements can cause a variety of different marks on the buttocks. Among these marks are welts, bruises and blisters.

The body marks considerably more from the same impacts when under the influence of blood-thinning substances such as aspirin or alcohol. Unlike redness, which usually fades away within minutes or hours, marks can last for many days, sometimes weeks. In the course of healing, they can just fade away, discolor (bruises), pop open (blisters), and they can also itch.

In extreme cases, spanking with implements can also break the skin, resulting in an open wound that bleeds. Any injury of such extent can result in permanent marks.

Anticoagulants, when taken before corporal punishment (for example Aspirin or alcohol), lead to stronger marks. So in consensual spanking, if marks are a problem, such substances should be avoided. On the other hand, if severe-looking marks are welcome, anticoagulants can be useful.

Common types of marksEdit


The most common type of "mark" is just the reddening of the skin with no actual damage done to any cells or vessels. The skin merely responds to the impact with a widening of the cappilaries, creating a reddening similar to blushing. For that reason, such marks are usually not considered injuries. An example of this is the handprint that comes from a spank with the open hand and which usually fades completely in less than an hour.


A petechia is a small (1–2 mm) red or purple spot caused by a minor bleeding into the skin from broken capillary blood vessels. Implements can leave red outlines on the skin because at the margin of where they impact with high velocity, the impact stretches capillaries sufficiently to tear them. These marks form only when the implement hits with high speed. Petechiae are typical for cane marks which look like two parallel "railroad tracks" on either side of where the cane hit.


A welt on a wrist.

A welt is a type of lesion: a skin region that is raised in a ridge or bump, and reddened. The reddening comes from a widening of cappillaries, and the ridge comes from a build-up of extracellular fluid (lymph).

In spanking, welts are well-known as a mark caused by thin, lightweight implements such as canes, switches, birches, or whips. Cane welts have a very characteristic appearance: each stroke creates not one line, but in fact two parallel lines. These come from the skin being abruptly stretched in the moment when the cane impacts at high speed, and are sometimes referred to as "tram lines".

Welts are painful to the touch, but can also itch. They can fade after hours or take weeks to heal - this depends a lot on the individual, and of course also on how severe the welt is. Hot water, such as from a bath or shower, may cause a seemingly healed welt to reappear.


A nine day old bruise.

A bruise (also known as a contusion or ecchymosis) is caused by blunt impact in which the capillaries are damaged, allowing blood to seep into the surrounding tissue. Bruises are characterized by black, blue or purple color hematoma in the days following, turning to yellow before fading away; a discoloration which does not blanch when pressed upon.

In spanking, bruises are typically caused by heavyweight implements such as paddles, straps or heavy canes. They take many days or weeks to fade, during which time they will often change in color.


A blister is a raised skin area that contains fluid - either blood or serum (the clear liquid portion of the blood). In spanking, blisters are rare, but can appear, especially from paddles with holes that are drilled sharp-edged, rather than well-rounded off.
