Acne・Acne Scars
Whiteheads
Whiteheads
Whiteheads are the earliest stage of acne, occurring when pores become clogged with sebum and dead skin cells, and the surface of the pore remains closed. They often appear as small, white bumps and can be easy to overlook.
Medically known as closed comedones, this stage marks the beginning of acne development, as acne-causing bacteria (Cutibacterium acnes) start to multiply within the clogged pore.
Blackheads
Blackheads
Blackheads develop when a whitehead progresses and the clogged pore opens up, exposing the trapped sebum to air. As the oil oxidizes, it darkens and forms a black or dark brown spot on the skin. Despite their appearance, blackheads are non-inflammatory and typically do not cause pain or swelling. They are often mistaken for small moles or pigmentation spots due to their color.
Inflamed Acne
Inflamed Acne
Red pimples occur when Cutibacterium acnes (acne-causing bacteria) multiply within the clogged pore and trigger inflammation in the surrounding skin tissue. This inflammation damages nearby cells, causing the pimple to appear red, swollen, and more noticeable. Medically referred to as inflammatory papules, this stage significantly increases the risk of post-acne scarring if not treated properly.
Yellow Acne
Yellow Acne
Yellow pimples, or pustules, develop when the inflammation from a red pimple intensifies and pus accumulates inside the lesion. Medically known as pustular acne, this stage occurs when inflammatory substances break through the follicle wall and spread to the surrounding tissue, worsening the overall skin damage. As one of the final stages of acne, yellow pimples can easily lead to lasting aftereffects such as pigmentation, raised keloid scars, or depressed acne scars (craters). Proper treatment and care are essential to prevent permanent scarring.

To effectively treat and prevent acne, it’s important to first understand the root causes and how acne develops.

Pore Blockage Caused by Excess Sebum
Deep inside each pore lies a sebaceous gland that produces sebum, an oily substance that normally travels through the pore to the skin’s surface, forming a protective layer that keeps the skin hydrated.
However, when sebum is overproduced or the pore becomes clogged, it can no longer exit the skin properly and begins to accumulate inside the pore.
This trapped sebum becomes a food source for acne-causing bacteria (Cutibacterium acnes) and other microbes, leading to the formation of whiteheads—the initial stage of acne.
 Pore Blockage Caused by Excess Sebum
Sebum Accumulates in the Pore
As more sebum builds up inside a whitehead, the pressure causes the previously closed pore to widen and open at the surface. When the trapped oil and debris are exposed to air, they oxidize and turn dark, forming what’s known as a blackhead.
At this stage, there is typically no pain or swelling, as inflammation has not yet occurred.
Sebum Accumulates in the Pore
Bacterial Growth in Clogged Pores Causes Inflammation
When non-inflamed whiteheads or blackheads are left untreated, more sebum continues to accumulate inside the pores. This buildup creates an ideal environment for Cutibacterium acnes (C. acnes) and other bacteria to grow. As these bacteria multiply, inflammation occurs, causing the area to become red, swollen, and painful.
Bacterial Growth in Clogged Pores Causes Inflammation
Worsening Inflammation and Pus Accumulation
As inflammation progresses, an enzyme called lipase produced by Cutibacterium acnes (formerly Propionibacterium acnes) breaks down the walls of the hair follicles. This allows the inflammation to spread to surrounding tissues, worsening the condition and leading to the formation of pus. The structure of the follicle becomes compromised, creating extra spaces where excess sebum can accumulate—thus repeating the acne cycle. As the follicle’s structure continues to deteriorate, it becomes increasingly difficult for acne to heal.
Worsening Inflammation and Pus Accumulation
Acne Heals but Leaves Scars Behind
Even after the inflammation subsides, acne can leave behind various types of scars. These may include persistent redness, pigmentation that appears brown or purple due to discoloration, or pitted scars (known as “craters”) caused by repeated breakouts that destroy the follicle’s structure. Regardless of type, acne scars tend to be difficult to treat. Redness and pigmentation can often be concealed with concealer, but crater-like scars are much harder to hide.

Personalized Acne Treatment Based on Individual Symptoms
At Bibi Clinic (Bianca Clinic), we carefully assess the condition of each patient’s acne and recommend the most suitable treatment based on a doctor’s diagnosis.

Sylfirm X: Uses radiofrequency to coagulate overactive sebaceous glands and surrounding inflamed blood vessels, effectively suppressing active acne.
Lalapeel: With anti-inflammatory properties, this treatment is gentle enough for acne-prone skin and helps reduce excessive sebum production, making skin less prone to breakouts.
Diode Laser: Utilizes thermal energy to suppress sebum production, sterilize acne-causing bacteria, and calm inflammation.

The right treatment depends on the severity and type of acne. If self-care has not led to improvement and you’re unsure how to treat your acne effectively, professional medical care from a dermatologist or aesthetic clinic is recommended. At Bibi Clinic, we offer customized treatment plans tailored to your skin’s condition. If you’re struggling with persistent acne, we encourage you to reach out for a consultation.
Personalized Acne Treatment Based on Individual Symptoms
Tailored Acne Scar Treatments from a Wide Range of Options
Acne scars can vary greatly in type and severity, and the most effective treatment depends on your individual skin condition. At Bibi Clinic, we offer a variety of treatment options—such as lasers, chemical peels, topical agents, injections, and microneedling—customized to your specific needs. The following treatments are commonly used to address acne scars:

Pico Laser:
Pico Spot and Pico Toning target melanin to reduce redness and pigmentation. Pico Fractional stimulates the skin’s natural healing process, improving depressed scars (craters).
Sylfirm X:
Activates fibroblasts to promote the production of collagen and elastin, reducing the appearance of indented scars.
Lalapeel:
Gently exfoliates dead skin cells to improve the texture of uneven skin caused by acne scars.
Rejuran:
Revitalizes skin cells, helping to repair depressed scars while also balancing sebum production and tightening pores.
Exosomes:
Accelerates skin regeneration through enhanced cell turnover, improving crater-like scars.
PRP Therapy (Platelet-Rich Plasma):
Promotes healing and skin regeneration to treat deep, pitted acne scars.
Juvelook:
Stimulates collagen production in the dermal layer, helping to improve the depth and appearance of acne scars.

Redness and pigmentation from acne may fade naturally as your skin’s turnover (regeneration cycle) normalizes. However, in many cases where turnover is disrupted or inflammation is prolonged, these marks can persist. Pitted acne scars are especially difficult to treat and typically cannot be improved with over-the-counter products or regular skincare.

If you’re seeking effective solutions for acne scars, we recommend considering professional treatment at a cosmetic dermatology clinic like Bibi Clinic, where personalized care and advanced technologies can make a real difference.
