📌 Acne Treatment at a Dermatology Clinic
Acne requires proper diagnosis to determine the underlying cause before beginning treatment.
Squeezing pimples without care or relying solely on over-the-counter medications are examples of improper approaches that can make acne worse.
To help prevent lingering redness, post-inflammatory pigmentation, or in more severe cases acne scarring such as crater-like marks, we recommend consulting a specialist clinic rather than attempting self-treatment.
💬 Advice from Our Specialist Physicians
“Acne is a skin condition. Early treatment is of the utmost importance. The longer it is left untreated, the longer and more costly the treatment process can become.”

🔬 Common Types of Acne
Skin concerns related to acne can broadly be categorized into the following three types based on how far the condition has progressed.
🟢 Non-inflammatory acne (early stage)
🔴 Inflammatory acne (progressed stage)
⚫ Acne Scars (severe stage)
Non-inflammatory acne represents the early stage, where care focuses on removing keratin buildup in the pores to prevent the growth of acne-causing bacteria (C. acnes).
As the condition progresses, inflammation develops, and if it becomes severe, acne scars can remain even after healing, making treatment more challenging. We recommend seeking a dermatological assessment and starting treatment before reaching that stage.
✨ At this stage, treatment can progress more quickly! ✨

Non-inflammatory acne is classified into whiteheads and blackheads. Taking appropriate care at this stage can help prevent progression to inflammation.

⚠️ Red and swollen. Please seek treatment promptly!

Inflammatory acne includes red papules and nodular acne, which can often be painful and, if left untreated, are prone to leaving acne scars.

When acne becomes severe, redness, post-inflammatory pigmentation, and crater-like scarring can remain even after healing. Treating acne scars requires a specialist approach.
📖 For Those Concerned About Acne Scars
We provide detailed explanations of treatment options tailored to each type of acne scar (redness, post-inflammatory pigmentation, craters, nodules, and keloids).

⚙️ How Acne Develops

💡 Key Points
① Pores become clogged
② Sebum accumulates
③ C. acnes bacteria multiply
④ Inflammation develops
⑤ If left untreated, acne scars may form…
💡 Causes of Acne

Common contributing factors to acne development include the following.
😰 Stress
😴 Lack of sleep
💧 Dry or oily skin
⚖️ Hormonal imbalance
😷 Prolonged mask wearing
These factors are associated with excess sebum production.
However, they are each only one of many contributing factors and do not represent the root cause on their own.
The underlying drivers of acne worsening are generally considered to be the inflammation and abnormal keratinization triggered by C. acnes bacteria.
🔬 Important Point
For acne that recurs even after improving lifestyle habits, treatment that directly targets the sebaceous glands themselves may be needed!

⚡ IC Clinic’s Acne Treatment | RF Needle “Agnes”
Our clinic offers a targeted acne treatment approach using the radiofrequency (RF) needle device “Agnes.”
The hallmark of Agnes treatment is that it delivers radiofrequency energy precisely to the sebaceous glands to disable them, addressing a key source of acne at its origin.
Because it acts directly on the dermal layer, this treatment is used for cases where surface-level skincare alone has not been sufficient.
The needles used with Agnes are extremely fine, so downtime tends to be minimal and the impact on daily activities is generally limited.
Scarring is also less likely to occur, which is another notable characteristic of this treatment.
In addition to its use for recurring acne, improvement in the appearance of fine lines and sagging may also be expected.
Treatment typically requires approximately 3 to 5 visits to complete.

✨ Three Key Advantages of Agnes
1️⃣ Targets the source to help reduce recurrence
2️⃣ Minimal downtime
3️⃣ Less likely to leave scarring

✨ [Case Study] Female patient in her 50s — Dermapen Microneedling treatment for acne scars on the right cheek (Updated August 3, 2025)
This patient is a woman in her 50s.
Due to repeated inflammatory acne in her younger years, crater-like acne scars (atrophic scarring) had formed on her right cheek, and she had been concerned about skin texture irregularities and difficulty with makeup application.
She visited IC Clinic Ueno, where after a thorough examination, treatment using “Dermapen 4” to support the skin’s natural healing process was proposed.
Over the course of several treatment sessions, the surface texture of her skin became smoother and her overall skin tone also appeared brighter.
She has since experienced a change toward skin she feels confident in even without foundation, and the patient has expressed satisfaction with her results.
