Acne is often considered a temporary skin issue during adolescence, but in reality, it is closer to a chronic inflammatory skin disease that recurs even in adulthood. Many people visit the clinic asking, "Why does it keep coming back even after treatment?" The key is not just to extract or calm it temporarily, but to manage the entire process, from sebaceous glands and inflammation to pigment and scars.
During summer, when sebum secretion is active, acne tends to become more prominent. Even if it seems to disappear at first, it often reappears, and in severe cases, it can leave acne scars. Therefore, an approach that looks at both the cause and the progression, rather than just temporarily suppressing symptoms, is necessary.
Why does acne keep recurring?
Acne occurs when excessive sebum secretion, waste products and dead skin cells in pores, proliferation of acne bacteria, and the resulting inflammatory response all interact. If only one of these factors is addressed, the others remain, making recurrence likely.

In the clinic, we see that even with the same acne, the condition varies for individuals with high sebum production, those with prominent red pustular inflammation, and those with both marks and hyperpigmentation. Therefore, a customized approach that considers the cause, symptoms, and skin type together is meaningful.
Viewing acne not as a single cause but as a complex disease involving sebum, inflammation, and pigment is the starting point for determining the treatment direction.
What is Double Gold PTT Total Care?
Yonsei Star Dermatology Sinchon's Double Gold PTT is a total care system designed to prevent scars and recurrence, consisting of a 1:1 customized program that considers the cause, symptoms, and skin type.

It is characterized by addressing complex changes such as redness, pigment, and scar marks together, and also caring for temporary irritation that may occur during the treatment process. Results may vary by individual.
This may be considered for those who

If you are in the following situations, you may consider discussing complex management like Double Gold PTT:
- Experiencing significant stress due to chronic acne
- Having excessive sebum production across the entire face
- Experiencing recurring red pustular acne
- Having inflammation, marks, and hyperpigmentation simultaneously
- Not having seen sufficient changes with previous treatments
Those who feel burdened by taking sebum control medication can also explore other options. However, it is best to decide on the appropriate direction after a direct consultation.

4 Directions of Action

Double Gold PTT is designed to act in the following four directions:
| Step | Direction of Action |
|---|---|
| Cause | Acts on acne bacteria and sebaceous glands to manage the root cause |
| Pores | Cleanses waste products and old dead skin cells in pores, providing pore care |
| Marks | Improves red inflammation and marks, and prevents depressed scars |
| Pigment | Alleviates brown hyperpigmentation, along with whitening and peeling |
The results and recovery patterns of each action may vary depending on the individual's skin condition.
3-Step Treatment Process

Double Gold PTT is structured to undergo a step-by-step penetration process.
- Step 1: Nano-gold penetration for cause and symptom management
- Step 2: Vascular laser penetration for mark and inflammation care
- Step 3: Gold-Diamond penetration for hyperpigmentation and whitening management
This process proceeds sequentially from the cause to marks and pigment.

While the basic program focuses on intensive care for acne cause management and recurrence prevention, there are also additional management steps.
What's different about Double Gold PTT Plus?

Double Gold PTT Plus adds premium care such as high-density ultrasound and oxygen therapy to the basic process, helping to maintain a healthy skin condition where acne is less likely to occur.

This approach is suitable for those who want to manage the cause and prevent recurrence, rather than just calming immediate symptoms. If acne marks have led to depressed scars, reviewing information on the causes and progression of acne scars may also be helpful.
Post-Treatment Lifestyle Management Tips
Daily care is as important as the procedure itself for the outcome. Please refer to the following items:
- Do not pick or irritate with hands
- Consistently use sunscreen
- Wash face gently, and keep skin sufficiently moisturized
- Follow the prescribed schedule and home care guide
The above care methods are general guidelines, and specific methods should be discussed with medical staff based on your skin condition. For similar concerns, the causes and management of acne or, if there are deeply depressed marks, Premium Customized Acne Scar Care can also be helpful.
If you are deeply concerned about recurring acne and marks, it is better to have your current skin condition checked and determine the direction rather than making a judgment alone.
