"Is it okay for a dermatology clinic to share this kind of information?"
Yes! It is okay! Here are 7 skin-damaging habits that you might easily miss.
I’ll tell you right away!
👇️Watch the video here👇️
Then let’s get started with what you’re curious about!

*The content in the video may vary depending on an individual’s condition and skin state.
The recommendations in this video are about managing personal lifestyle habits, so the suggested guidance may differ depending on the degree of skin concerns.
First. Avoid mouth breathing!

👄Let’s develop the habit of breathing through the nose, not the mouth 👃
There are several main reasons for this!
Facial shape changes:
If the habit of breathing through the mouth becomes fixed, the jaw may be pushed backward and the face may become longer.
Facial asymmetry:
Breathing only from one side or using the mouth muscles unevenly can disrupt the left-right balance of the face.
Reduced skin elasticity:
As the muscles around the mouth sag, the nasolabial folds deepen and the overall facial elasticity decreases, making aging appear faster.
Second. Please avoid tough foods! (feat. jaw muscles)

💪 The jaw muscles are muscles too! If they are used too much, various negative effects can occur.
Development of a square jaw (masseter hypertrophy):
When chewing hard and tough foods, the jaw muscles (masseter muscles) are used excessively, causing the muscles to enlarge,
and the face may gradually change into a more angular square jaw.
Worsened facial asymmetry:
This is often accompanied by the habit of chewing mostly on one side,
which can cause one muscle to develop abnormally and lead to asymmetry in the corners of the mouth or the jawline.
Tension in the lower face:
If the muscles around the jaw are always tense, blood flow around the area can be disrupted,
making the face look swollen often and giving the impression of a stiff, stubborn expression.
Third. Avoid looking down at your smartphone too much

📱 Why smartphone posture creates a "double chin"
Sagging caused by gravity:
A posture where the head is bowed down is directly affected by gravity, pulling the skin around the chin downward,
which can soon lead to a more noticeable double chin!
Deeper neck lines:
Strong pressure is applied to the neck skin, which repeatedly folds,
creating deep horizontal neck lines and giving a more aged appearance.
Forward head posture and rounded shoulders:
If you develop a forward head posture where the neck moves forward, the chin may appear to be pushed back relatively,
which could create the illusion that chin fat is more prominent..ㅠ
Fourth. Proper mewing exercises

Improving the jawline and double chin:
When the tongue is pressed broadly against the roof of the mouth, the muscles under the chin are pulled up firmly,
which can help reduce the double chin area!
Natural correction of mouth breathing:
When the tongue is placed in the correct position, the mouth naturally stays closed and the habit of breathing through the nose develops,
which can also help improve the tendency for the face to look longer!
However, with mewing exercises, it is difficult to judge based on photos alone!
Therefore, doing it as accurately as possible is important,
and depending on the structure of an individual’s mouth, the effect may be absent or minimal.
Fifth. Avoid the habit of resting your chin on your hand

🪑 How the habit of resting your chin on your hand affects appearance
Main cause of facial asymmetry:
If continuous pressure is applied to only one side of the jaw, the temporomandibular joint can shift to one side,
which may worsen lip asymmetry and the left-right imbalance of the face.
Wrinkles and sagging skin:
If you keep pushing up or pressing the skin of the cheeks and chin with your palm, the nasolabial folds deepen,
and reduced skin elasticity makes sagging more likely.
Cervical twisting and forward head posture:
Resting your chin on your hand bends the head and rounds the shoulders, causing deformation of the cervical spine (neck bones),
which eventually becomes a cause of disrupting the overall facial line.
Sixth. Avoid crossing your legs too often

🦵 The mechanism by which crossing your legs can create facial asymmetry
You may wonder how it could possibly have that effect!
Tension in the jaw joint and skull:
When the neck is twisted, uneven force is applied to the muscles around the jaw (such as the chewing muscles),
which can alter the position of the jaw joint and induce facial asymmetry.
Distortion of facial muscles through the fascia:
As the fascia connected from the toes to the head is pulled to one side,
it can eventually disrupt the balance of the entire face, such as the height of the eyes and the asymmetry of the corners of the mouth.
Seventh. Avoid using straws

🥤 Why using straws is a major cause of aging around the mouth
Wrinkles around the lips (lip lines):
The repetitive motion of puckering the lips to suck through a straw
can overly contract the muscles around the lips and may cause fine vertical lines!
Worsening of nasolabial folds:
As the orbicularis oris muscle, which is the muscle around the mouth, is used repeatedly, the surrounding skin folds,
which eventually becomes a cause of deeper nasolabial folds.
Reduced skin elasticity around the mouth:
If continuous stimulation and pressure are applied, the collagen layer of the skin around the mouth can be damaged,
causing the lip line to lose elasticity and sag!
