Acne is not merely a superficial skin problem but rather a chronic condition involving recurrent inflammation of hair follicles and sebaceous glands. For those starting treatment, the most common question is, “What method is right for my current skin condition?” The before-and-after photos presented below are unretouched actual records of a patient who received Double Gold PTT acne treatment at Yonsei Star Dermatology Sinchon, and treatment results may vary depending on individual skin conditions.
What is the principle behind Double Gold PTT treatment?
Gold PTT is a treatment designed to selectively act on overactive sebaceous glands by delivering gold particles into pores and sebaceous glands, then absorbing laser energy. Double Gold PTT intensifies this process. Its characteristic feature is that it addresses not only superficial acne but also the fundamental structures that cause inflammation.
Since acne results from a combination of factors such as sebum, pore keratin, and inflammation, it can be helpful to consider a sebaceous gland-level approach rather than just calming the surface.
In the clinic, under the same name "acne," oily skin with excessive sebum, skin with scattered small bumps, and red, inflamed, pustular acne all manifest differently. Therefore, understanding the condition before treatment is crucial for the outcome.
What skin concerns can be considered?
Double Gold PTT aligns with concerns frequently mentioned by patients during consultations, such as:
- When sebum secretion is high and pores feel enlarged
- When small bumps repeatedly appear
- When red, inflamed acne frequently occurs
- When changes feel slow with general topical medications alone
However, not all individuals falling into the above categories are suitable for the same treatment, and actual applicability will be determined through consultation. If you have similar concerns, we recommend reviewing information on Acne Symptoms and Causes.
How should I view before-and-after photos?
Before-and-after photos are reference materials to gauge the direction of treatment. The images below are actual unretouched records, but even with the same treatment, the degree and speed of change can vary depending on individual skin condition, lifestyle habits, and recovery ability.
When viewing photos, it is helpful to look not just at "whether acne has reduced," but also at the redness, inflammation patterns, and changes in skin texture. If you would like more detailed information, you can use Chat Consultation for Acne Treatment.
Important Aftercare to Combine with Treatment
Treatment alone does not conclude everything; daily care plays a crucial role in maintaining the results.
- Gently cleanse twice a day with a mild cleanser
- Avoid picking or touching acne with your hands
- Consistently moisturize and apply sun protection
- Maintain a consistent lifestyle rhythm, including sleep and eating habits
If you are concerned about marks left after acne has subsided, a separate approach may be necessary. In such cases, we would review information on Acne Scar Treatment or phased management directions such as the Triple Acne Package.
Important Points to Remember Before Treatment
Acne treatment often proceeds in stages tailored to the skin condition, rather than being completed in a single session. Since there can be individual differences in effectiveness and recovery patterns, the process of finding the right method for you through consultation with a dermatologist is paramount.
When you are unsure whether a specific procedure is suitable for you, or if another method might be better, it is safest to determine the direction through a specialist's consultation.
