When I first saw this issue
I wondered
But I was driven by the sense of mission of the Friends of Women
This issue has to be studied carefully
Let's take a look at the research results
This line under the chest
Conditional female classmates
Can check it out now
There is no under the chest
Don't be "discouraged" if you find that you don't
It doesn't mean you won't have it in the future
I'll tell you about it
What exactly is this line?
Why not elsewhere?
But here's it
Affected by the position of the chest
The chest is probably located
Between the 2nd-6th ribs
People have 12 ribs
That is, the top and bottom of the chest
Both have rib distribution
Many girls should be very understanding
When you hold your head up and your chest up
The ribs above do not affect anything
At most, it's a little skinny
But the ribs at the lower end of the chest
There is no coverage of chest fat
will be raised
And then with a fat belly underneath
interaction
And our daily hunched sitting posture
will increase this interaction force
day after day
This crease may be
Permanently under the chest
Affected by the shape of the chest
Affected by gravity
Normal chest morphology
There is a sagging of 1-2cm
There are also girls who are born with a low chest line
The sagging of the breasts is more pronounced
When the chest is sagging
The skin is pulled by pressure
可能也会形成褶皱
furthermore
Girls also go through some special periods
For example, pregnancy and lactation
When pregnant
Hormone levels rise
The mammary glands and fatty tissue will stretch the breasts
The hormone drops after the end of lactation
These tissues shrink rapidly
However, the suspensory ligament cannot be reduced
Chest sagging can be more severe
This fold is getting deeper and deeper
Article 1 of possible formation
Permanent pleats
Girls are in the period of development, pregnancy, and lactation
Hormones in the body are all changed
This hormone
May mobilize melanocytes to work
Synthesize more melanin
Strip-shaped pigmentation classes
It might look like a black line
But don't worry too much about that
Hormone levels in the body return to normal
It's nothing
But
If it is a sudden growth of this sediment spot
It may be caused by endocrine disorders
This disease is called in Chinese
Superficial thrombophlebitis of the chest wall
This type of line has several characteristics
In most cases, it is only 2-3cm long
Pull the skin tight and touch it
Cord-like induration will be found
It will hurt a little more when you press it again
The age of onset is 20 to 40 years
Females are about 2-4 times more numerous than males
See here
Vaguely is not a feeling
It's a pretty serious disease
In fact, this disease is very weak chickens
The cause is unknown
It will disappear on its own in 2-3 months
Finally, there is another case
This line is the "indentation"
It's the one who was strangled by underwear
And the research proves
The pressure caused by these few underwear parts
It's relatively large in itself
It is more likely to cause strangulation marks
If the underwear size is not suitable
will deepen this indentation
That's it
Aim for this line that may appear under the chest
Some of the studies that have been carried out
All in all
There is a line under the girl's chest
It has nothing to do with being fat or thin
It's just innate
