Does every body have birthmarks

Answer 1

NO

In fact, most people have a mark somewhere on their body at birth: may be a light reddish/ pink patch on the back of the head/ neck, & if under the hair not noticeable. Many other marks (especially "strawberry marks") often fade quickly, frequently disappearing altogether in the first few years of life; later, people don't realise they had them - unless photos or parents inform them of the fact!

Some birthmarks are little more than dimples or very small reddish or blue patches on the skin - usually so faint they are not generally recognised for what they are. Also, newborns often emerge quite "battered & bruised" from passage down the birth canal, and such lesions, although rarely permanent, may be considered birthmarks - marks present on the body at birth.

Often people have more "noticeable" birthmarks in places that are not easy to see: unless informed of this by parents or others they may not know about their marks. This is surprisingly common: a former girlfriend of mine had a fairly large (couple of inches across) dark purple birthmark on the back of her head, above the hairline - many people must have seen this during her life (eg hairdressers), but she didn't know she had it until I told her! She was so amazed by this she didn't really believe me until I photographed it for her.

Almost all people have at least a few moles on their skin - a totally "flawless" skin would be very rare indeed! Many moles emerge during childhood, so strictly speaking are not birthmarks, but their formation is generally genetically determined, so in a sense they are.

Birthmarks come in many forms: the "classic" brown/ purple/ black marks present from birth that most think of as birthmarks occur in roughly 10% of most populations, but there are numerous other types of mark that may be present at birth but which fade/ disappear totally quite quickly. Because such marks are not extant or obvious in later life, people often overlook them. In truth, however, it's very rare for a baby to be born who has no skin mark of some sort as a momento of the event.

Answer 2

Most people are born with some sort of mark on their skin, but the majority of these fade or disappear in the early years of life. A very common birthmark is a reddish or pink patch on the back of the neck or head, and most of these will later be concealed completely when the hair grows and thickens. Another common birthmark (especially in those of Asian descent) is the bluish/ grey "Mongolian mark" usually located on the buttocks or lower back, and the majority of such marks disappear in childhood.

Many birthmarks are little more than bruises or compression spots caused by the trauma of the baby's passage down the birth canal, and most of these will disappear quite rapidly after birth. The type of pigmented, larger marks (usually brown, or black or purple) that most think of as "birthmarks" are relatively rarer (2-5% of newborns in most populations) and are usually permanent. Larger vascular birthmarks (eg "port wine stains") sometimes get larger after birth, and such marks are generally the ones which may require medical treatment, either for cosmetic reasons, or because - in a few cases - they're causes of, or symptomatic of, more serious underlying conditions. A few males (0.2 - 2%, depending on population group) develop a brown, often hairy, mark on the shoulders or upper torso during puberty or early adulthood: this "Becker's Nevus" is genetically determined, and it's emergence seems to be triggered by the testosterone surge of puberty. Because it's genetically determined it is regarded as a "birthmark", even though it develops later in life.

Most people have smaller pigmented marks ("moles") on their bodies, but most emerge later in life (typically at around 7 years, or older), and, therefore, are not really "birthmarks".

So, yes, most people are born with a "birthmark" of some sort, but the majority of these marks will disappear in early life. The majority of the most common birthmarks that don't fade/ disappear completely will be concealed by head hair, and consequently many don't even know they have these marks. More obvious birthmarks of the "classic" kind are relatively rarer, and bearers of such marks tend to be regarded by others as "having birthmarks". In fact, however, nearly all humans do have a mark on their skin at birth.

Answer 3

No, not all babies are born with a birth mark.

Also, many birth marks begin to fade between toddler age (2 years) and middle school age (8-9 years).

Answer 4

Of course not.

Answer 5

No not everyone has birthmarks.

Answer 6

All of them.

Answer 7

No.
