Yes, no and maybe, say physiologists. There is little data to go on but some experts say that a smack should not leave a bruise, which is caused by blood leaking from ruptured vessels.
It may take 5 to 7 days for the swelling to go down, and 10 to 14 days for the bruising to fade. It may be hard to eat at first.
A punch or a slap does not have to be exceptionally powerful to kill somebody. A hit that is delivered quickly and at a particular angle can cause torsional forces to the neck and head, injuring the arteries that supply blood to the brain.
The red reaction: It is due to filling of the smallest vessels of the skin, called the capillaries. It is as a result of release of histamine from the damaged skin which dilates these capillaries. The red reaction outlines the stroke and is sometimes called as red line.

PATTERNED BRUISES
Slap marks are a fairly characteristic and recognizable form of bruising. Occasionally a full imprint of the hand may be seen. More typically a series of diverging rays, making a fan shape, will be seen.
Conclusions: Scar redness fades on average at 7 months. This is influenced by the wound type and position. The authors advocate the use of the term "rubor perseverans" to describe the physiologic redness of a normal scar as it matures beyond the first month, a process that does not involve inflammation.
SLAPS AND FINGER WHIPS: The effectiveness of these strikes is a result of the psychological reaction. They are not knockout strikes, but they can set up an opponent for defeat a lot faster and more effectively than punches.
Punching does more damage, but slapping usually hurts more than punching. For example, a pro boxer would likely punch harder than slap. A pro slap competitor would have a higher slapping force.
Unusual sites for bruising (suspicious) include the buttocks, trunk (stomach), genitals, ears, and back of hands. Bruising that is bilateral, symmetric or geometric raises concerns.
A hickey, hickie or love bite in British English, is a bruise or bruise-like mark caused by kissing or sucking skin, usually on the neck, arm, or earlobe. While biting may be part of giving a hickey, sucking is sufficient to burst small superficial blood vessels under the skin.
Aside from the common bruise, bleeding into the skin or mucous membranes is a very significant sign and should always be checked out by a health care provider. Redness of the skin (erythema) should not be mistaken for bleeding.
Blood leaks into tissues under the skin and causes a black-and-blue spot that often turns colours, including purplish black, reddish blue, or yellowish green, as the bruise heals. Bruises hurt, but most are not serious and will go away on their own within 2 to 4 weeks.
Slaps Constitute Battery
If someone intentionally slaps you, regardless of the amount of force, and causes you some sort of legally recognizable damage, you can sue him or her for battery.
Slapping someone involves the physical contact of hitting your hand across another person's face or other part of their body. The physical contact itself makes the act assault, but it would most certainly be considered assault if there was force in the slap.
Touch is a word that encompasses several kinds of feeling : temperature, vibration,sight, ,deep and light touch and pain. When you are slapped you stimulate your touch and pain receptors and the message travels to brain where you then become aware of the pain.
A liver shot or liver punch is a punch, kick, or knee strike to the right side of the ribcage that damages the liver. Blunt force to the liver can be excruciatingly painful, and an especially effective shot will incapacitate a person instantly.
In time, some collagen breaks down at the site of the wound and the blood supply reduces. The scar gradually becomes smoother and softer. Although scars are permanent, they can fade over a period of up to 2 years. It's unlikely they'll fade any more after this time.
What are the signs of a scar? When a scar first develops on lighter skin, it's usually pink or red. Over time, the pinkish color fades, and the scar becomes slightly darker or lighter than the color of the skin.
A hand contusion usually results from a direct blow to the hand. Any blunt trauma with sufficient force to propel its energy into the muscle can cause a contusion.
