Two Types of Acne, Two Treatment Paths: A Dermatologist's Guide

5/5/2025

Welcome to Skin Insights by YSBB.

Have you ever looked in the mirror and noticed tiny white bumps or painful red pimples on your face? These are two very different types of acne—commonly known as whiteheads and inflammatory acne. They may look similar at a glance, but their causes, treatments, and risk of scarring are quite distinct.

Today, let’s take a closer look at both types of acne and how to treat them effectively from a dermatologist’s perspective.


1. What Is Whitehead Acne (Comedonal Acne)?

Whitehead acne is a non-inflammatory form of acne caused by sebum becoming trapped in pores. It appears as small, firm bumps that are white or slightly yellow, typically without redness or swelling. This is considered an early-stage form of acne.

  • Excess sebum production
  • Poor exfoliation causing clogged pores
  • Hormonal changes (puberty, menstrual cycle, etc.)
  • Improper cosmetic use or inadequate cleansing

Treatment Options:

  • Exfoliating agents (AHA, BHA, tretinoin)
  • Professional acne extraction and skincare treatments
  • Sebum-reducing treatments like laser or oral isotretinoin if needed
  • Proper moisturizing and sun protection

With early care, whitehead acne can often be resolved without scarring.


2. What Causes Inflammatory Acne?

Inflammatory acne occurs when whiteheads become infected with Cutibacterium acnes bacteria and trigger an immune response. This leads to redness, swelling, pain, and sometimes pus. If left untreated, it can damage the deeper layers of skin and leave scars.

  • Untreated whiteheads becoming inflamed
  • Excess oil production combined with bacterial overgrowth
  • Poor habits such as picking or squeezing pimples
  • Overactive immune response

Treatment Options:

  • Topical or oral antibiotics
  • Anti-inflammatory injections (e.g., triamcinolone)
  • Anti-redness lasers such as Clarity II

Prompt treatment is essential to prevent dark spots and pitted scars.


3. How Do Scarring Risks Differ?

  • Whitehead Acne: Minimal skin damage, low risk of scarring if treated properly
  • Inflammatory Acne: Can damage the dermis, leading to high risk of pigmentation and scarring
  • Recovery Speed: Whiteheads heal quickly, while inflammatory acne often needs more time and treatment

Whitehead acne rarely causes permanent damage if addressed early. But inflammatory acne can affect deeper skin layers, often requiring additional treatment for scars.


Final Thoughts

Not all acne is the same. Whiteheads and inflammatory acne differ not just in appearance, but in how they should be managed. Ignoring early-stage acne or neglecting inflamed breakouts can lead to pigmentation and permanent scarring.

At YSBB Skin Clinic, we:

  • Accurately diagnose your acne type and stage
  • Offer personalized treatments including extraction, medication, laser, and injections

Early treatment can prevent scars and help you achieve healthy, clear skin. If you're dealing with stubborn breakouts, don’t wait—come see us for a professional evaluation.

Your Acne Scar Treatment Roadmap: From CROSS to Fractional Lasers

4/28/2025

 
Picture

Welcome to Skin Insights by YSBB.

While acne itself often fades with time, acne scars can persist and significantly affect skin texture and overall appearance. Especially in cases of depressed scars or enlarged pores, skin can appear uneven and tired.

Today, let’s explore essential points to know before starting laser treatments for acne scars, guided by a dermatologist’s expertise.


1. Do Different Acne Scar Types Require Different Treatments?

  • Ice Pick Scars: Narrow and deep scars
  • Rolling Scars: Broad, shallow, and uneven depressions
  • Boxcar Scars: Wide, sharply defined depressions
  • Enlarged Pore-Like Scars: Scars that resemble large pores

Each scar type demands a customized treatment approach. At YSBB Skin Clinic, we design tailored solutions based on your specific scar patterns.


2. Are Special Treatments Needed for Ice Pick Scars?

Ice pick scars are often too deep and narrow for standard laser treatments to yield satisfactory results. In such cases, we employ the CROSS technique.

  • Uses high-concentration TCA (trichloroacetic acid) to stimulate collagen production
  • Targets the scar base to encourage natural skin remodeling
  • Particularly effective for deep, narrow scars

3. How Are Deep, Wide Scars Treated?

For deep and wide scars with strong adhesions, subcision is recommended. Subcision involves using a specialized needle to release tethered scar tissue, allowing the skin to lift naturally.

  • Ideal for deep, broad, and tethered scars
  • Careful control of incision depth and range tailored to each patient's skin

4. Which Lasers Are Used for Acne Scar Treatments?

At YSBB Skin Clinic, we combine multiple technologies to address different scar types for optimal results.

  • Fractional Laser (CICU): Microthermal zones stimulate collagen for deep scars like boxcar scars
  • PicoMLA: Micro Lens Array technology improves rolling scars by smoothing the surface
  • Pinhole Method (CO2 Laser): Targets wide or raised scars by creating tiny perforations for remodeling
  • Fractional Radiofrequency (3DEEP FSR): Improves skin texture and firmness for stretch marks and broad atrophic scars
  • Secret RF: Delivers radiofrequency via microneedles to tighten enlarged pores and enhance skin elasticity

5. How Many Sessions Are Needed?

Acne scar treatments typically require multiple sessions to achieve the best results.

  • Generally, 3 to 5 sessions are recommended
  • Treatments are spaced 4 to 6 weeks apart to allow for skin regeneration
  • Gradual collagen remodeling leads to smoother, healthier skin

6. What Should You Be Careful About After Treatment?

After acne scar laser treatments, some temporary skin reactions are expected.

  • Redness, swelling, and scab formation may occur
  • Strict sun protection is essential
  • Avoid excessive skin irritation

Final Thoughts

Successful acne scar treatment isn’t about one aggressive laser session. It requires careful scar analysis, personalized treatment strategies, and consistent follow-up care.

At YSBB Skin Clinic, we combine CROSS technique, subcision, CICU fractional laser, PicoMLA, CO2 pinhole method, 3DEEP FSR, and Secret RF to design comprehensive, individualized scar treatment plans.

Let’s achieve clear, confident skin together!

Think Twice Before You Squeeze That Blackhead

4/25/2025

Welcome to Skin Insights by YSBB.

Do you often squeeze blackheads or use pore strips hoping for cleaner skin?
If so, you’re not alone — but be careful.
Improper oil control and forceful extractions can actually damage your skin.

Let’s talk about why squeezing sebaceous filaments and blackheads can lead to bigger problems — and how to manage sebum the right way.


What Is Sebum — and Why Should You Be Cautious?

• Sebum (oil) is a natural protective layer made by your skin.

• It helps prevent moisture loss and shields against external irritants.

• Excess sebum, however, can clog pores and lead to blackheads or acne.

• Many people try to over-remove oil, which can make things worse.


Common Problems from Over-Extraction or Harsh Sebum Control

1. Enlarged Pores:
Repeated squeezing weakens skin elasticity and stretches pores.

2. Dark Spots or Scarring:
Aggressive pressure can cause inflammation, leading to PIH (post-inflammatory hyperpigmentation) or pitted scars.

3. Oil-Water Imbalance:
Harsh cleansers or peel-off products strip essential oils, causing more dryness — and a rebound in oil production.

4. Worsening Acne:
Using fingers or unsterilized tools introduces bacteria into the skin, increasing the risk of inflammatory acne.


How to Manage Sebum Safely

• Wash your face gently twice a day with a low-irritation cleanser.

• Use different products for T-zone (oilier) and U-zone (drier) areas.

• Oily but dehydrated skin needs more moisturizing, not less.

• Use sebum-absorbing masks only once a week and always follow with calming care.

• Never extract at home — visit a dermatologist for sterile, professional care.


What We Offer at YSBB Skin Clinic

• Manual extraction of blackheads and whiteheads followed by soothing care.

• Clarity II laser for pore and oil control in acne-prone skin.

• Prescription treatments tailored to oily and combination skin.


Final Thoughts

Sebum is not your enemy.
The goal isn’t to remove all of it, but to maintain a natural balance that suits your skin type.

If you’ve been squeezing too often or using overly aggressive products, it’s time to reassess your routine.
For safe and effective oil control, consult a skincare expert when in doubt.

CROSS Treatment for Acne Scars: Dermatologist-Approved Method for Deep Scar Repair

4/25/2025

 
Picture

Welcome to Skin Insights by YSBB.

Acne is a common skin condition, but in severe cases, it can leave behind deep, lasting scars. CROSS (Chemical Reconstruction of Skin Scars) is a focused and effective treatment designed to improve these acne scars, especially the deep, narrow ones that are often difficult to treat.

At YSBB Skin Clinic in Seoul, we use CROSS as one of our preferred procedures for scar revision. In this article, we’ll walk you through how CROSS works, its clinical benefits, and what to expect from the treatment.


What Is the CROSS Technique?

CROSS stands for Chemical Reconstruction of Skin Scars, a method that has brought remarkable progress in acne scar treatment over the past few decades. This procedure uses high-concentration trichloroacetic acid (TCA) applied precisely into each acne scar to trigger localized wound healing and collagen regeneration.

Though once considered aggressive, it has proven to be safe and highly effective when performed by a trained professional.


Why Choose CROSS? Key Benefits

  • Especially effective for deep, narrow (icepick or boxcar-type) scars
  • Targets only the scar tissue — leaving surrounding skin unharmed
  • Minimal downtime compared to ablative lasers
  • Quick procedure, easy to fit into busy schedules
  • Can be combined with other treatments for enhanced results

How CROSS Treatment Is Performed

Step-by-step:

  • Skin is thoroughly cleansed
  • A fine applicator (such as a toothpick or micro needle) is used to place high-concentration TCA into each scar
  • The acid causes a controlled wound reaction, promoting regeneration of new tissue
  • The surrounding skin is not affected, ensuring faster healing and precision

Is CROSS Safe?

Yes — when done by an experienced dermatologist. Since TCA is applied only to scars, the risk of side effects is minimal. Temporary redness, swelling, or crusting may occur, but usually resolve within 1–2 weeks.

As always, proper patient evaluation and post-treatment care are essential to ensure safety and satisfaction.


How Effective Is CROSS?

CROSS is especially useful for:

  • Deep, narrow acne scars (icepick scars)
  • Stubborn scars that have not responded well to other treatments

With repeated sessions, the skin slowly fills in from the inside as new collagen forms. Visible improvement is usually seen over a few weeks to months.


Precautions & Aftercare

  • Temporary redness, swelling, and scabbing are common and part of healing
  • Use sunscreen daily to prevent post-inflammatory pigmentation
  • Avoid harsh skincare and sun exposure during the healing phase
  • Always follow your dermatologist’s instructions closely

What’s Next for CROSS Treatment?

CROSS technology continues to evolve. Improved application tools and combination therapy with other treatments (like microneedling or RF) are expanding its potential and safety profile.

At YSBB, we often combine CROSS with other scar therapies depending on scar type and skin condition — allowing a more personalized and effective outcome.


Final Thoughts

CROSS is one of the most promising treatments for deep acne scars — especially for patients who have tried multiple options without success. It’s safe, affordable, and shows impressive results when performed by an experienced dermatologist.

If you are considering acne scar treatment, speak to our experts at YSBB Skin Clinic. We’ll evaluate your skin type and scar severity and recommend the most effective path forward.
