Many people are concerned about the red marks that remain even after acne has subsided. When thinking of acne scars, it's easy to first imagine indented marks, but it's equally common for redness to persist for a long time, making the skin tone dull. Let's summarize why only redness remains for a long time after inflammation has passed, and how vascular lasers like Vbeam Prima are used to remove red acne marks.
The prominence of redness around an acne lesion is a phenomenon that occurs as capillaries in the dermis expand during the inflammatory response. Many people neglect it, thinking it will naturally fade over time, but in reality, the marks can remain for several months or even over a year, so careful management is necessary.
Acne progresses as inflammation occurs around the sebaceous glands. In this process, local blood flow increases and capillaries expand to repair damaged tissue. The more severe or repetitive the inflammation, the greater the degree of vascular expansion, which in turn causes red marks to persist for a long time. If you have a habit of squeezing or repeatedly irritating the skin, the inflammation may deepen and vascular damage may also worsen, which could slow down the fading of the marks, so caution is needed.
When looking for ways to remove red acne marks that don't disappear for a long time, the first thing to consider is restoring the condition of the blood vessels rather than pigmentation. Once expanded, capillaries are often difficult to noticeably improve with self-care focused on whitening ingredients. Therefore, improving expanded blood vessels with vascular lasers such as Vbeam Prima is considered, with the expectation of achieving a substantial reduction in redness.
The Vbeam series is a representative laser device series used for treating red acne marks. Among them, Vbeam Prima selectively reacts to hemoglobin in blood vessels using two pulse wavelengths: 585nm and 595nm. Treatment is performed by generating heat as hemoglobin in the expanded blood vessels absorbs laser energy, and this heat gradually coagulates the vessel walls, inducing them to be naturally absorbed over time. A characteristic feature is that it can selectively treat only expanded blood vessels while minimizing impact on surrounding normal tissue. Vbeam Prima also incorporates a cooling system (DCD, Dynamic Cooling Device) to reduce thermal damage to the skin surface during the procedure. It can help alleviate not only red marks but also the inflammatory response of early acne, so it is often combined with acne treatment depending on the condition.
As such, red acne marks are often caused by expanded blood vessels rather than pigmentation, so it is important to identify the exact cause before determining the treatment direction. Since it is a procedure that requires precise adjustment of wavelength and energy intensity according to the skin condition, it is safer to receive vascular laser treatments like Vbeam Prima from medical professionals with extensive clinical experience.
The necessary treatment interval and number of sessions may vary from person to person depending on the degree and extent of redness. Immediately after the procedure, redness or heat may temporarily appear more prominent. Combining UV protection and soothing care during this period can help with the recovery process, so it is advisable to receive guidance on pre- and post-procedure care methods.
In Summary
If you are looking for ways to remove red acne marks, it is advisable to undergo a precise diagnosis at a clinic first to identify the cause of the marks, rather than relying on self-care. If a customized treatment plan is established after comprehensively examining the skin condition and the degree of vascular expansion, redness may fade and skin tone may return to a more stable state. If you have any questions, you can find answers through consultation inquiry.
