什么是口周纹？

Perioral lines, or decree lines, refer to longitudinal wrinkles extending from both sides of the nose to the corner of the mouth. They are closely related to factors such as repeated contraction of facial muscles, collagen loss, and skin relaxation. Decree lines are a type of facial expression lines., especially when smiling, talking or making expressions, are more obvious.

Causes of perioral lines

1. Excessive use of facial muscles
   Frequent facial movements for a long time, such as laughing, talking, and exaggerated facial expressions, will accelerate the formation of law lines. Especially the excessive use of the levator labrum muscle will pull on the skin and cause the law lines to deepen.

2. collagen loss
   With age, the collagen and elastic fibers in the skin gradually decrease, the skin support decreases, and the lines appear naturally.

3. Dry skin and aging
   皮肤缺水、缺乏保养，加上紫外线伤害、不良生活习惯（如吸烟、熬夜），都会加速皮肤老化，加重法令纹。

4. genetic factors
   Some people are born with deep Dharma Lines, which is related to inheritance, but can be improved through nursing and medical aesthetics.

Expression and influence of perioral lines

1. cosmetic effect
   Deep Dharma lines can make the face look tired and serious, and even give people the impression of "impatience" and affect social image.

2. 心理影响
   很多人因为法令纹加深而产生焦虑，甚至影响自信心，尤其是女性在职场或社交场合中。

3. Facial contours change
   Severe law lines can lower the middle and lower parts of the face, causing problems such as "double chin" and "sagging law lines", further accelerating facial aging.

Daily care methods

1. Moisturizing and hydrating
   保持皮肤水分充足是改善法令纹的基础，建议使用含有hyaluronic acid、甘油、神经酰胺等成分的保湿产品，每天坚持涂抹。

2. 防晒
   Ultraviolet light is one of the main culprits of skin aging. Be sure to protect yourself from sun protection when you go out. Choose a sunscreen with SPF30 or above to avoid direct sunlight.

3. mild cleaning
   Avoid using irritating cleansing products and choose mild amino acid cleansing to reduce damage to the skin barrier.

4. expression management
   减少过度做表情的习惯，比如不要频繁大笑、夸张地说话，可以有效减缓法令纹加深。

Medical beauty improvement plan

If the effect of daily care is limited, or the law lines are already obvious, the following medical beauty methods can be used to improve them:

1. botulinum toxin injection
   通过阻断肌肉收缩，减少法令纹的动态表现，效果通常在1-2个月后显现，维持时间约4-6个月。

2. filler injection
   Fillers such as hyaluronic acid and collagen can directly fill the law lines and restore facial fullness. The effect is immediate and lasts for about 6-12 months.

3. Line carving improvement
   通过可吸收蛋白线刺激collagen regeneration，提升面部松弛组织，改善法令纹和面部轮廓。

4. Picosecond laser/Thermagi
   Use radio frequency or laser technology to stimulate skin regeneration and promote collagen reorganization, which is suitable for improving static law lines and skin relaxation.

5. Facial lift surgery
   For people with severe law lines and facial droop, it can be directly improved through facial lifting surgery.
