Red marks that remain after acne subsides are a common skin concern that lingers on the face for a while even after the breakouts have cleared, causing distress. The first question that usually comes to mind is one: "Will they disappear on their own if left alone, or do I need treatment?" To answer directly, red marks are often a precursor to scarring, and it is reported that starting treatment early is more beneficial for recovery.
At Yonsei Star Dermatology Sinchon, we see many patients who visit during periods of relative free time, such as school breaks or year-end, to address acne marks they've put off. We've compiled ways to use this seemingly short period more efficiently.
Why Red Marks Don't Disappear Easily
Acne is a common skin problem that frequently occurs not only in adolescents with active hormone secretion but also in adults due to environmental factors. Because it's so common, many people tend to dismiss facial symptoms as minor.
The problem lies in what follows. If redness persists and inflammation continues in the area where acne was present, it can eventually develop into scars or hyperpigmentation, leading to rough skin texture and uneven facial tone. This can result in a messy or aged appearance, so rather than waiting for it to improve naturally, we recommend considering laser treatment before red marks harden into scars.
The Cause of Redness is Blood Vessels in the Skin
A primary reason for redness around a lesion is the excessive proliferation of blood vessels in the skin. When our body is damaged, it increases blood vessel activity to supply nutrients needed for recovery, and this process can make red marks more prominent.
If acne bacteria or other inflammation remains, the likelihood of recurrence also increases, making it difficult to expect satisfactory results even with treatment. Therefore, a comprehensive approach is needed that goes beyond merely addressing the visible red marks, to also care for the remaining inflammation within the skin to prevent them from hardening into red acne scars.
It is safer to understand the current red marks as an early sign of scarring. It is reported that early treatment is more advantageous in reducing the possibility of them hardening into scars.
What Role Do Vascular Lasers Play?
Vbeam Prima, known as a vascular laser, is a device widely used to improve skin redness. It is used to treat the blood vessels identified as the cause of redness, and it can also be expected to play a role in preventing severe, depressed scars from forming beyond just red marks. It is reported that prompt treatment can help in returning to an even skin tone.
Commonly considered factors when determining the treatment direction include:
- The degree, distribution, and duration of redness
- Whether inflammatory acne is currently active
- Whether depressed scars are already present
- Skin type and tendency for hyperpigmentation
- How much recovery time can be allocated for daily life
If you have any questions, please feel free to ask through Red Mark Treatment Consultation.
To Reduce Recurrence, Start with Inflammation
Another reason why management can feel difficult is the high possibility of frequent recurrence. To prevent red marks from reappearing, it is important to address both sebaceous glands and acne bacteria. In particular, extractions performed in an unsanitary environment can worsen inflammation and leave depressed scars, so caution is needed.
In such cases, applying intensive care like Gold PTT in addition to vascular laser treatment can be beneficial for reducing the likelihood of recurrence and maintaining results for a longer period. The key is to approach it in stages: first stabilizing the active acne itself, and then addressing the remaining marks.
| Stage | Main Goal | Approach |
|---|---|---|
| Active Inflammation | Stabilize acne bacteria and sebaceous glands | Calm breakouts with intensive care |
| Red Marks | Improve hyperproliferated blood vessels | Alleviate redness with vascular laser |
| Depressed Scars | Prevent and restore hardened scars | Gradual management with scar treatment |
What's the Difference Between Marks and Scars?
The red marks currently visible can be considered early symptoms of scarring. At the stage where only the skin surface color has changed, they are relatively easy to treat, but over time, if tissue becomes depressed or raised, the difficulty of management increases. If they have already hardened into depressed acne scars or acne scars, separate scar treatment may be necessary.
By also focusing on managing inflammation that has not fully subsided within the skin and choosing appropriate laser treatment, it can help prevent red marks from progressing further and return to clear skin. However, results may vary individually, so the process of creating a plan tailored to your skin condition comes first.
In Summary
Red marks are something that only worsen with neglect. Comprehensive management that addresses both inflammation and blood vessels before they harden into scars is the fastest way to return to an even skin tone.
If you are concerned about persistent marks, please feel free to inquire through Consultation for Current Condition-Specific Management.
