Everyone is familiar with the experience of their face turning red when exposed to cold winter winds. However, if your cheeks and nose remain red even after the cold has passed, or on days that aren't particularly cold, it's difficult to see it as a simple weather reaction. Why does this redness persist without subsiding?
In the clinic, we often see people who say, "I thought it was because of the cold, but it's still the same even in spring." If facial redness goes beyond a temporary reaction and lingers, it's necessary to identify the cause and establish an appropriate management plan.
Facial redness is ultimately due to blood vessels
The reason the face easily flushes is that blood vessels are densely distributed in that area. When stimulated, the blood vessels expand, causing redness to show through the skin's surface.
Especially for those with fair skin, the epidermis tends to be thin, making blood vessels more visible, and redness can appear more pronounced even with the same stimulus.
What causes redness?
The factors that cause redness are not singular. The frequently cited causes are as follows:
| Cause Type | When does it appear? |
|---|---|
| Temperature changes | When there is a large temperature difference, such as moving from a cold place to a warm indoor environment, blood vessels repeatedly constrict and expand |
| Food/Alcohol | Blood vessels temporarily expand due to spicy and irritating foods or alcohol |
| Hormonal changes | Cases related to hormonal changes, such as menopause |
| Medication | Long-term use of steroids or certain high blood pressure medications |
In particular, some high blood pressure medications contain ingredients that expand blood vessels, so it's advisable to examine the connection between the medication being taken and the symptoms.
Face sensitive to temperature changes
The first cause that comes to mind is, of course, temperature changes. In environments with large temperature differences, such as moving from a cold place to a warm indoor environment, blood vessels react quickly, and redness becomes prominent.
If such a reaction appears briefly and then subsides, it's not considered a major problem. However, if the same stimulus is repeated, the red state may persist for longer.
Food and hormones also have an impact
It's common for blood vessels to temporarily expand when eating spicy and irritating foods. The phenomenon itself doesn't last long, but if it continues repeatedly, the facial redness may persist for a longer period.
It is also related to hormonal changes. In menopausal women, related symptoms can persist for a long time, and in men, situations requiring management may arise with long-term use of steroids or high blood pressure medications.
As symptoms appear due to a combination of various factors, if the redness does not return to normal after temporarily turning red, or if it recurs or persists for a long time, it is advisable to find the exact cause through facial redness consultation.
If you are concerned about redness but don't know where to start, you can easily ask your questions via chat consultation if you are curious about the cause of redness.
The reason not to neglect it: Rosacea
Leaving redness untreated can lead to more advanced skin problems. A prime example is rosacea, a chronic inflammatory disease that primarily affects the central part of the face, such as the nose and cheeks.
The initial sign of rosacea is facial flushing. If both cheeks become increasingly red and inflammation becomes frequent, it may be a change beyond simple redness.
In this case, managing redness also means monitoring the progression of rosacea, and it is significant for maintaining overall skin health.
Management begins with identifying the cause
The first thing to do is to identify the cause of the symptoms. Here are some items to check:
- Is there a pattern of the face quickly turning red after drinking alcohol or eating irritating foods?
- Is the redness temporary or does it persist for a long time?
- Is inflammation or a sensation of heat accompanied?
- Are any medications being taken related to blood vessel dilation?
If you tend to flush easily from alcohol or irritating foods, adjusting your lifestyle is paramount. If the redness does not subside for a long time rather than being a temporary reaction, a more fundamental cause will be identified, and full-scale management will be carried out together.
How does vascular laser approach it?
Checking the condition of blood vessels is very important in managing redness. Since enlarged blood vessels intensify redness, vascular lasers such as V-beam Facial Redness Treatment are used to target and reduce them.
The Vbeam Prima has dual wavelengths of 595nm and 1064nm. The advantage of dual wavelengths is that it can access not only superficial red blood vessels but also deeper blue blood vessels. It is also used to treat large areas by adjusting the output and pulse duration, and good results are reported in V-beam Vascular Lesion Treatment.
During laser irradiation, a cryogen is sprayed onto the skin surface to protect it and reduce skin damage during the procedure. However, results and reactions may vary individually, so it is necessary to confirm through consultation whether the method is suitable for your blood vessel condition.
In conclusion
When the skin shows redness, it is also a sign that heat is not escaping and remains in that area. If heat lingers for a long time, it can eventually lead to secondary troubles.
If facial redness does not subside for a long time, we recommend getting an accurate diagnosis now and establishing an appropriate management plan. If you are wondering which management is right for you, please feel free to inquire via chat consultation for redness laser management.
